One of many morphs of my station. Mostly WWII equipment with some from the 1950’s and 1960’s. Definitely “EMP Proof”. Patch panels allow me to select any of about 15 antennas and connect them to any of about 12 radios. With the patch panel design, they don’t go through a single “choke point”; they can all be run simultaneously. The VHF panel is visible, the HF panel is out of the photo.
The station is normally powered by commercial power but I also have a solar panel which charges a 12 volt deep-cycle battery system. That battery can naturally run all the 12 volt equipment but it also powers a 120 VAC Inverter when needed. I can also quickly patch in a gas powered AC generator if necessary. Very flexible. If the commercial power fails, a relay drops out which then connects the solar charged battery into the system. Automatic.
Above: One of my favorite combinations, even now, is the Hallicrafters HT-40 and BC-348-R receiver for CW on 80 and 40 meters. A typical novice station from the 1960’s and it still works quite well today. The HT-40 has a very clean CW note with good shaping – and none of the phase-noise garbage of some modern rice-box transmitters. The classic BC-348 is very stable and the crystal filter is quite effective, although not always needed.
The S-120 is a recent addition – I had sold my original S-120 which was my first “real” shortwave radio as a kid. The “informative” slide rule dial even told you where to tune to receive “Paris”, “China” and other DX locales. By today’s standards its pretty marginal but I didn’t know any better back then – logged lots of DX with it and it still sounds pretty good on SWBC. I have even worked some CW with it, but that is another adventure.
One fond memory as a thirteen year-old during the S-120 days was listening to lots of interesting non-voice signals that crowded the bands back then – and wondering what they were. I lived about a mile from Mitchel Air Force Base on Long Island in the 1950’s – 1960’s. As a kid I could recognize dozens of different USAF aircraft by sound alone as they flew nearly over our house on approach to Runway Three-Zero.
There was a peculiar, distinctive signal at many points on the S-120 dial. Sort of like a continuous, droning, guttural “Grrrrrrrr” sound. It sounded like a B-17 four engined bomber in flight. (Que the sound track from “12 O’Clock High”) I just KNEW that’s what I was listening to on the radio. It wasn’t until later in life when I was trained as a Navy ELINT intercept operator that I discovered what that sound actually was – a 4-channel multiplexed radio teletype transmitter.
Hmmmmm, The B-17’s had four Wright Cyclone R-1820 radial engines running asynchronously. Four independent asynchronous Baudot RATT signals. Nine cylinders per engine. At at 5 bits each character plus a start and stop pulse (7 bits total). Acoustically / spectrally speaking, a pretty close match! No wonder I was fooled1! The East Coast of the US had lots of that kind of military traffic going on back then…
Below is my station back in New York in 1967. I had just upgraded from Novice to General and was running a Lafayette HA-350 receiver and a Hallicrafters HT-40 transmitter with dipoles and verticals. I had 2 Lafayette HE-90 CB rigs that I had converted to 10 meters. One was used for the local County RACES net on 28.720 AM and the other was used for DX’ing with my 4 element Cush Craft yagi. I worked a lot of Europeans and a few African stations with that 5 watt radio on 10 meters. Plate modulated with my “Green Hornet” mike, it sounded great and it had a hot Nuvistor front end – very sensitive for the times. As a Novice, I had worked 40 DX countries with the HT-40 and the J-38 straight key, mostly on 15 meters with my only crystal for 15 meters: 7038 tripling to 21.114 MC. If it managed 10 watts output on 15 meters it would be lucky. But 10 watts can go a long way!
The Lafayette HA-350 was looked down upon by people who apparently never tried one – it was a pretty good receiver for the price, especially for a novice CW operator. Built by Trio for Lafayette, Trio was later renamed “Kenwood”.
It was a bit unusual looking with its brushed aluminum panel with chromed accents but it has a heavy steel cabinet and chassis. Its IF bandwidth was a bit too narrow for AM but it was pretty good for SSB and also CW; selectable filters were not an option. The HA-350 is allegedly the first non-Collins “ham receiver” that used a mechanical filter. Mine has more than adequate sensitivity.
The ARRL Book on Vintage Radio mentions this receiver as being one of the many “75A4 Clones”. I have not compared schematics but I will take that statement at face value. (The Japanese were quite happy in copying others’ designs.)
The Novice CW bands were not particularly crowded back then. The mechanical filter in my set ultimately failed about 30 years after I bought it (not hermetically sealed) so I replaced it with a Collins F455-3.1 KC mechanical filter. Still works great.
The HT-40 is a very good CW rig, producing a nice clean, stable note. It used screen modulation on AM with the Green Hornet mike but I rarely used it on phone, preferring CW, a preference I still have. It tuned quickly and easily, had a clear CW note. I eventually sold it but then bought a “nostalgia replacement” which I still have – its a fine backup rig.
I eventually built a Heathkit HG-10 VFO and my Dad bought me a Hammarlund HK-1B Electronic Keyer. I didn’t have a paddle so I made one with a hack saw blade, screws and some scrap wood – it worked great. I eventually wore out the relays in the keyer and then upgraded it to a a Curtis CMOS keyer chip and switching transistor built inside the chassis – its still operational. Then it was a DX-100 and a Heathkit SB-102, Swan 350 and a few other fun rigs.
Above: A shot of my gear, circa 1968. The great Heathkit DX-100 and my Swan 350. I used them both mostly on 10 meters with my 4 element Yagi. Worked a lot of DX with them both. Also shown is the Hammarlund HK-1B electronic keyer. In the rack below is a 500 Watt transverter I designed as a school project. It runs a 4CX300A power tetrode and a solid state receiving converter. It was driven by the converted Lafayette HE-90 on 10 meters to produce a BIG signal on 2 meters AM. Just in time for 2 meters AM activity to die off in favor of FM!
Although not a “base” system, I also had a Motorola T-43 “narrowbanded” FM 2-meter mobile in my old Bronco. A 6146 on 2 meters – amazing! Circa 1973.
I had them crystalled on 146.940, then the national simplex frequency before 146.520 became popular. These rigs sounded great – nice “punchy” audio, perfect for police cars! I donated the T-43 to a local railroad museum (caboose radio) and I still have the portable. Fun, learned a lot in the early days of Ham FM.
Below is a shot of my set up in the barracks at the Great Lakes IL Naval Base. I was running a Hustler 4BTV up on the roof of the 5 story building. I mainly used it to keep in touch with buddies back home in NY. Still having fun with the HE-90 converted to 10 meters.
Below is the station shortly after I moved to California. All commercial stuff at this point, the Mil gear was in storage. Photo approximately 1979.
Below is the setup in the barracks at Navy OCS, Newport RI in 1972. I had to cache the Swan 350 in the “hide site” during the day (not specifically verbotten but that’s just because no one thought anyone would ever try to do this!). I had run a long wire antenna made of # 34 Ga copper from the roof of King Hall to an adjacent wing, 4 stories up. Installed at Zero-Dark-Thirty while on a “Fire and Security Watch” (no fires or security incidents occurred during this evolution). It could not be seen from the ground and the feedline was easily hidden from surprise inspectors looking for dust or other discrepancies. I used it to keep in touch with buddies back on Long Island on 80 meters at night. Looks like I had a spare set of G.E. 6HF5 finals “at the ready” on the shelf in case of battle damage.
