Another experimental station, call Sign "4HW" and operated by Mr. Harold D. Walsh, has been added to the list of stations operating in Queensland. Mr. Walsh informs us that he is working almost nightly on 240 metres, and is getting excellent reports as to volume and modulation. Mr. Walsh, however, states that as not many listen on 240 metres, very few have heard his station up to the present, not knowing that it is operating. He is working C.W. and telephony, and will be pleased to work with any other licensed experimenter, and to receive reports from any district stations who hear this station. "4HW" is still in the experimental stages, and for this reason the operator is anxious to receive reports. The station is situated on the top of the premises of Messrs. G. O. Wills and Sons, Ltd., 110 Elizabeth Street, Brisbane.http://nla.gov.au/nla.news-article20984950 ITEMS OF INTEREST.

LOCAL BROADCASTING. On Monday and Wednesday nights listeners-in on low wave lengths heard 4HW, Brisbane, broadcasting gramophone selections and recitations. This proved to be a private set, owned and operated by Mr. H. D. Walsh, from the premises of H. O. Wills, Elizabeth-street, where the necessary apparatus was installed by him. Mr. Walsh stated that he had received notifications from Sydney, Southport, Toowoomba, Redcliffe, and other places that he had been picked up; but only those working a low wave length (he was working 240) got the calls or those knowing he was broadcasted who specially tuned in. Further broadcasting will take place on Saturday and Sunday. It may be mentioned that one operator, on a crystal set, with no extra aids, got Mr. Walsh's programme on Monday night between items by 4QG, and tuned in again on Wednesday night.http://nla.gov.au/nla.news-article220621833 PRIVATE STATION The Daily Mail 7464 Queensland, Australia 30 January 1926 6 July 2025 17 National Library of Australia 1926 02 Brisbane Daily Mail journalist visits Walsh's 4HW and reports on the facilities A LOCAL STATION. EXPERIMENTER AT WORK. An invitation to inspect the experimental transmitting station operated by Mr. H. D. Walsh was cordially accepted by the writer, and resulted in a very pleasant half hour being spent in this enthusiast's company. Mr. Walsh is anxious to have reports from any listener who happens to hear him working, and would be pleased to carry out tests with other amateurs who have transmitting stations. Report have been received from 2GR, Sydney, Toowoomba, and other far-reaching places, where experimenters have received telephony and telegraph signals from him with exceptionally good results. The station's call letters are 4HW, and it operates on a wave length of 240 metres. Transmission usually takes place from 8 p.m. to 10.30 p.m. on Saturdays and Sundays; occasionally on week nights at the same time, and frequently at midday from 1.30 p.m. to 2 p.m. An Armstrong tuned plate circuit, employing Heising modulation on choke control is used. The speech from the microphone is first amplified by means of a speech amplifier (U.V.199) before being applied to the grid of the modulator valve. Both modulator and oscillator valves are U.V.202 type. The filament current is supplied from a 10 volt accumulator, and the plate voltage from a 600 volt D.C., generator belt driven from a 1 h.p. motor. Meters are provided to indicate radiation, plate voltage, plate current, filament voltage, and filament current. Great credit is due to Mr. Walsh, and it must be admitted that the broadcast listener of today owes his thanks to pioneers such as he. Similar efforts in other parts of the world are directly responsible for the present day success in broadcasting, and undoubtedly perseverance will still further tend to improve its quality.http://nla.gov.au/nla.news-article220625706 A 'LOCAL STATION The Daily Mail 7470 Queensland, Australia 6 February 1926 6 July 2025 17 National Library of Australia As previous, further detail, clearly penned by Walsh himself PRIVATE STATION. LOCAL TRANSMITTING. MR. H. D. WALSH'S PLANT The apparatus installed at experimental station 4HW, described in last Saturday's issue, comprises a 10 Watt transmitter and a low wave receiver. The station is owned and operated by Mr. H. D. Walsh, and is situated above the premises of Messrs. G. O. Wills and Sons Ltd., 110 Elizabeth-street, Brisbane. The transmitter employs one oscillator tube and one modulator, both being 5 Watt Radiotron tubes. The oscillating circuit consists of the Armstrong tuned plate system, with no coupling between grid and plate coils, regeneration being obtained and controlled by a small five plate condenser between grid and plate of the oscillator. A switch is provided by which the modulator may be paralleled with the oscillator to give greater power for CW work. Modulation is effected by choke control (Heising method). The aerial and plate circuit coil consists of 18 turns, 16g bare copper wire wound on an ebonite strip frame, and is tuned by two movable clips. The grid coil is 22 turns 18g enamel wound on a varnished cardboard former, and is tuned by a variable condenser. A blocking condenser inserted between plate and coil keeps the high plate voltage off the aerial coil. This condenser has mica dielectric, its capacity being .002 mfd. It is specially made for transmission and will withstand 4000 volts. The aerial series condenser is variable, .0015 maximum capacity, and is of the ordinary type, except that the plates are immersed in oil to increase capacity and break down voltage. The grid condenser is a good standard made of ordinary receiving condenser, mica dielectric, capacity .002 mfd. THE POWER SYSTEM. A Stromberg-Carlson low resistance microphone is used, the face having been cut away and a mica diaphram substituted for the standard metal one. A spark coil is used as a modulation transformer, and by means of a plug and two jacks the modulation may be impressed direct on to the modulator tube, or on to a speech amplifier, consisting of a UV199 tube, which outputs through a standard audio transformer on to the grid of the modulator tube. A grid bins of 42 volts is used on the modulator. Bias on the oscillator grid is supplied by a 5000 ohm leak. Filament current for the power tubes is supplied by a 10-volt accumulator, which is kept fully charged by means of a mechanical rectifier. Plate current is supplied by a generator delivering a maximum power of 100 watts at 600 volts, its power being controlled by a field regulator. The generator is driven at a speed of 3100 r.p.m. by belt from a 1 h.p. 3-phase A.C. motor, and a small electric fan forces a breeze through to keep the armature cool. The natural commutation ripple of the generator is smoothed out by a filter system consisting of an iron core choke in each lead with a 1 m.f.d. condenser across the output ends of the chokes. A further choke is used in the positive lead of the plate supply to act as a modulation choke, and consists of the secondary of an old telephone translator coil. A hot wire meter indicates radiation, which, with the aerial in present use, is approximately 750 milliamps. A moving coil meter in the plate circuit indicates plate input current, and a voltmeter is inserted between plate and filament to indicate plate voltage. Needless, to say, these meters must be of the highest possible quality and workmanship. There are a voltmeter and ammeter in the filament circuit, the voltmeter being controlled by a two-way switch so that the voltage across the filament of either of the power tubes may be easily read. The receiver employs a two-valve circuit designed for maximum efficiency and ease of control, especially on amateur wavelengths (i.e., 150-250 metres). The circuit is a modification of the Reinartz, add employs what is known as the Chambers system of feed back, this being necessary to permit oscillation on the lower wavelengths. Greater amplification cannot be used, owing to interference from power induction and other causes. (Start Graphic Caption) A diagram of the plant installed by Mr. H. D. Walsh.

CRYSTAL RECEPTION OVER LONG DISTANCES. EXPERIENCE OF BRISBANE AMATEURS. Mr. N. J. Dutton's experience in getting 3LO Melbourne on a crystal set, as related in the wireless circle of March 7, has created a vast amount of interest, and many letters on the subject have been received, from which we select the following:— Mr. Harold D. Walsh (A.48W [sic, A4HW]) writes: "During the past few months several reports have been published stating that 3LO has been received on crystal sets, and there has been much discussion as to whether the reception was direct or due to reradiation. This led the writer to carry out some experimental work with crystals, which proved that it is possible to receive 3LO on a crystal without the use of any valve amplification. The method used was as follows:— First, a two valve set with standard PI circuit was used to test the volume of the distant station, which was found excellent, its strength on a small loud speaker comparing very favourably with the local station. A simple crystal set was then made up, using a 50 turn coil with condenser in parallel, and a stage of audio frequency was added, using a transformer and 201A valve. By means of a wave meter the aerial circuit was accurately tuned to 371 metres, and the wavemeter buzzer was used to find the most sensitive spot on the galena crystal. When the buzzer was turned off the music was audible in the phones, very loud, being a dance tune. This ceased, and 4QG was announced, but in the interval a woman's voice singing could be distinctly heard. The attempt was then abandoned until 10 o'clock, and immediately the amplifier was turned on, music was audible at quite good strength. After about five minutes, 3LO Melbourne was announced, and was very clear and quite loud, static being at a minimum. The amplifier was then disconnected and phones connected in place of the transformer primary winding. The crystal appeared to have been upset, and for some time nothing could be heard. However, the buzzer was again brought into action, and the crystal adjusted, when a song was heard, followed by 3LO's announcement. A piece of synthetic crystal was then tried, but was soon discarded in favour of galena. Reception on the crystal alone was very faint but quite audible. The writer did not have at hand a made up crystal set, which was the chief reason why all the above preparations had to be made, but there is no reason why, with reasonable care, 3LO should not be received on any well made crystal set, given a good aerial and careful operation. RERADIATION THEORY. The writer has never put much credence in the reradiation theory. There has been much talk of reradiation from "powerful" sets. This requires some thought. It is obvious that no set can radiate energy unless it is in a state of oscillation. We now come to the 'powerful' valve receiver. In the case of a three valve set, using two stages of audio frequency amplification, a little thought will show us that, even if the detector valve is oscillating, there can be no more reradiation than with a single valve set. With a set employing one or more stages of radio frequency amplification, the position is slightly altered, since, in most sets, the plate circuit of the detector is seldom coupled to the aerial, and radiation will not take place. Even if the detector is so coupled, it is only the power of the oscillating detector that will be radiated; from this it can be seen that the amount of radiation is not affected by the 'power' of the receiver. Another point to consider is that the radiation from an oscillating receiver consists of a pure continuous wave at the frequency to which the receiver is tuned at the time, and it is not possible for this wave to be modulated by the very feeble incoming wave from the distant station. If this could be done, relay broadcasting would be a very simple matter. Some vendors may object to this statement and quote the principal of heterodyning, as used in the super heterodyne, but should be remembered that in this case the frequency of the signal is considerably altered and also some strength is lost in the process. The writer does not see that a weak signal can have its strength increased by reradiation from a neighbouring receiver, and has recently proved the above theories by various experiments, consisting mainly of the use of two and even three receiving sets with the aerials very close to each other, and no sign of an increase of signal strength due to reradiation could be detected. It will be apparent therefore, that any listeners-in who hear southern stations on their crystal sets may rest assured that it is direct reception, and they will have every right to be elated at their success, as it is only a few months since the writer read in an English magazine an account of crystal reception over 400 miles, which was considered a record." FURTHER CONFIRMATION. Mr. G. C. Finch, manager of the radio experimental staff of Mick Simmons, Ltd., writes:— "In reply to Mr. N. J. Dutton's letter, Sunday, March 7, I would state that what Mr. Dutton hears on his crystal set, is direct reception from 3LO Melbourne. I have been experimenting for some time past on the reception of Melbourne and Sydney on a crystal set, and find that providing one has a good aerial and earth, 3LO comes in quite good on any ordinary crystal set, after 4QG closes down. The best crystal to use is certainly the Neutron. It is thought by many experimenters that reception from Melbourne on a crystal set is obtained only through heterodyning of a powerful valve set operating close, and although it is possible, the reception in this manner is entirely different. To those who will try Melbourne on a crystal set is really easy, and I have often wondered that it is not more generally known, as 3LO is one of the best stations in the world. 2BL Sydney also comes in on a crystal at times, but 3LO can be held throughout, and with comfortable hearing strength." SYDNEY AND MELBOURNE. Mr. A. Davis, of Boondall, Sandgate line, writes:— "In reply to Mr. N. J. Dutton, who wants an explanation of receiving Melbourne on crystal. I wish to state that I have been able to get 2BL Sydney and 3LO Melbourne before 4QG started and when there was no possibility of it being reradiated from a valve set in this district." SIMILAR EXPERIENCE. Mr. H. E. Hannington, of Parkham-avenue, Nundah, writes:— "I have had a somewhat similar experience to that of Mr. Dutton. On Wednesday, 3rd instant, after 4QG had closed down, I was tinkering with my set (No. 2 Gecophone) and, much to my surprise, I heard what I thought was a variety show, but ascertained next day that 3LO had broadcasted an act from the pantomime, 'Aladdin.' I might mention that this was the first time I had ever attempted anything after the local station had closed down. On Thursday night I was at it again after 4QG had closed down, and had great success, as I heard practically all the balance of the programme. I also heard the items listed on Friday, Saturday, and Sunday nights. The items were as follow:— Thursday, March 4.— 10.15 p.m., man singing, jazz music, and weather information. Miss Donaldson sang "Something I Can't Realise," Francis Lee sang "A Little Lullaby," two fox trots (1) ?, (2) "Just Wanting You," Jack O'Hagen sang "Dear Old Pal," two fox trots (1) "Tanglefoot," (2) "I'm Sitting on Top of the World," close down two minutes to 11 o'clock.http://nla.gov.au/nla.news-article220640973 OUR WIRELESS CIRCLE.

STATION 4HW. The apparatus installed at Station 4HW, owned and operated by Mr. Walsh, Toorak Hill, Hamilton, consists of a 35-metre transmitter, two 20-80 metre receivers, a 150-250 metre 'phone transmitter, a 120-250 metre receiver, a one, a two, and a three valve broadcast receiver, and a longwave receiver. The two short-wave and the long-wave receivers each employ two valves. There are two wavemeters, covering a band of 15-3000 metres, and the necessary power transformers, recti-fiers (thermionic and electrolytic), accumulators, B. batteries, and chargers (syncronous, thermionic, and electrolytic types being employed), The 35-metre transmitter consists of a 5-watt tube in shunt-fed coupled Hartley circuit. With a power input of 45 watts at 500 volts, a radiation of 200 milliamps is obtained. One low-wave receiver employs Reinartz circuit, the other the three coil Meissner. The longwave receiver and broadcast receivers employ the old reliable PI circuit. The 'phone transmitter consists of a 5-watt tube in Armstrong's reversed feedback circuit with shunt feed, and with power input of 35 watts at 450 volts radiates 750 milliamps. Another 5-watt tube is used in a Heising modulation system, and two Marconi R tubes supply speech amplification when necessary. Power supply is obtained from a transformer using the AC mains and delivering 10 volts for filaments and 700 volts each side of centre tap for plate supply. This is rectified by two 201A tubes, with grid and plate connected together, and the resulting DC is smoothed out by passing through the secondaries of two Ford spark coils, connected in parallel, and shunted by a 2 mfd. condenser on each side The maximum output available from this arrangement is 120 milliamps at 560 volts. A 90-volt accumulator B battery supplies plate voltage for receivers and amplifiers and two 6-volt accumulators supply filament current. Leclanche cells are used for grid bias where necessary. There is considerable auxiliary apparatus, in all, 20 variable condensers, 26 valves, 12 electrical meters, and 10 batteries being employed. Four separate aerials and two counterpoises are used. A 600-volt DC generator also is available for experimental purposes. The 35-metre apparatus is not in full use at present, owing to lack of time, but it is hoped that good work will be done with it in the near future. The 'phone transmitter is in regular use, and may be always heard on Sunday nights, commencing at 9.30. Gramophone records, piano pieces, and recitations are transmitted, and all reports received during the week are acknowledged over the air. Reports have been received from Melbourne, Sydney, and various places in between. One has come from Charters Towers, and a large number are received from country parts of Queensland. All reports are greatly appreciated and should be addressed to H. D. Walsh, Toorak Hill, Brisbane. Distant reports are acknowledged in letter as well as over the air.http://nla.gov.au/nla.news-article21027207 ITEMS OF INTEREST.

By "LISTENER." Another Two-Valver writes: Dear Mr. Listener,— I am a regular reader of your "Radio Topics," and enjoy them very much. I notice that "Two-Valver" in Radio Topics of November 3 throws out a challenge to radio fans. I accept that challenge, and I hope that "Two-Valver" will receive it in the spirit in which it is offered. "Listener" will you kindly adjudicate, please?" "Two-Valver" says that with an outdoor aerial 50 feet long and not higher than 10 feet, and using a two-valve variocoupled regenerative set (one detector and one stage LFA, dull emitter valves), he received, in succession one Sunday night 4QG, 2FC, 2BL, 3LO, and 5CL. Here is a summary of reception accomplished on my various sets. With a crystal set (no condenser or variocoupler), an outdoor aerial about 80 feet length, 20 feet lead-in, 30 feet high, soldered water-pipe earth, I received 4QG (old), 4QG (new), 4HW (amateur), VIB (commercial). Using the same aerial and earth system, and operating a single-valve set (Ediswan AR06 dull emitter), I logged the following stations: 4QG (old), 4QG (new), VIB (commercial), 4HW (amateur), 2BL, 3LD [sic, 3LO], 5CL (phones and speaker). With a two-valve set, identical with that as described by 'Two-Valver,' with the outdoor aerial already described, the following stations have been received: 4QG (old), 4QG (new), VIB (commercial), 4HW, 2FC, 2BL, 2VE, 2VW, 3LO, 3AR, 3FA, 3FW, 5CL. With the same set, but using, indoor aerial only, consisting of a double line of small gauge enamelled wire running through the house, about 8 feet high from the floor, and about 48 to 50 feet long, the following stations have been brought in (phones or speaker): 4QG (old), 4QG (new), 2BL, 2FC, 3LO, 3AR, 5CL. "Using neither aerial nor earth, 4QG has been received — not loudly, but quite distinctly. This set can also bring in 2FC on the Amplion (junior de luxe) speaker, whilst 4QG is on the air, and at times, whilst speech or voice is being transmitted from 4QG, the latter station is almost completely wiped out, no wave trap being used. I know there are many other radio fans who can beat the above, and I would be very glad to hear of their results, with similar sets, through the medium of your valuable columns." http://nla.gov.au/nla.news-article179576407 RADIO TOPICS The Telegraph 16,830 Queensland, Australia 10 November 1926 6 July 2025 13 (SECOND EDITION) National Library of Australia 1926 12 1927 1927 01 1927 02 1927 03 1927 04 1927 05 1927 06 1927 07 Walsh placed equal third in the QRTL reliability relay test "QTC" Transmitters' League. The Queensland Radio Transmitters' League, which was formed in April of this year, has entered upon the second stage of its activities — that of organised publicity and promulgation of reports of its doings and plans for the future. It has brought out the first issue of its magazine, "Q.T.C.," which is to be published monthly in the interests of experimental radio. From its columns we learn that the league aims, by co-operation and co-ordination of effort to obtain better conditions for its members, and, incidentally, for the amateurs and experimenters of the Commonwealth. It is pointed out with a great degree of truth that the regulations governing wireless telegraphy in Australia, especially as far as experimental activities are concerned, are very much out of date, having been formulated at a time before radio had made the rapid strides which it has been achieving in the last decade. It is therefore essential that the laws governing wireless be brought up to date so as to meet the needs of the experimenter. The league aims to secure an amendment of the regulations to permit of the handling of traffic by experimental stations upon similar lines to those at present in operation in the United States. The league purposes providing telephone lectures and classes of instruction in code on the 200-250 metre band. The first reliability relay test conducted by the league resulted as follows: 4HG (H. Bell), 6 points 1; 4AW (A. Walz), 4 points 2; 4GO (G. Oxlade), 4 points 2; 4NW (T. Starkie), 2 points 3; 4HW (H. Walsh), 2 points 3; 4JG (C. Grant), 1 point 4. The following stations, being originators, were not eligible for points, but the number gained are shown for general information: 4RB (R. Browne), 6 points; 4CG (C. Gold), 4 points; 4LJ (Leo. Feenaghty) 2 points. The Q.R.T.L. is holding a convention on Thursday of Exhibition week. "QTC" contains much useful information for amateur transmitters, and has been well edited by Mr. Leo. Feenaghty, care of the Main Roads Commission.http://nla.gov.au/nla.news-article182126276 "QTC" The Telegraph 17,050 Queensland, Australia 27 July 1927 6 July 2025 15 National Library of Australia 1927
