Go Back In Time – Vintage Film

29 June 2024 at 21:24
Turning back time to virtually witness a critical historic method of shortwave communication using the fundamental mode of continuous wave modulation. This is a film from 1944, teaching the basics of Morse code, for military comms. What is the proper (and most efficient) technique for creating Morse code by hand, using a manual Morse code […]

My old valve radio station

Going through some old photos today I found a few great memories from the past of my old valve radio stations that I’d restored over the years.

These old radios gave me some wonderful moments over the years and a fair few hours of restoration to get them into operational condition. They sounded great on air and I often got comments from other amateur stations about how warm the audio sounded. Some did also mention the drift of the transmitter with temperature changes but, you just have to accept that when using vintage radio equipment.

Above is my old FT101 line up. It consisted of the great FT101E transceiver, a complete standalone solution that was extremely popular in its day. Below it is the FT101 line up made up of the FT101 transmitter, FR101B receiver and matching speaker.

Top right is the lovely Trio TS520S with the matching digital frequency display which is incredibly rare and very sought after today.

These radios gave me a lot of pleasure for many years and I wish I still had them today.

My second Yaesu valve line up took a lot more restoration than the 101 series and was quite challenging at times but, with a lot patience and time spent sourcing parts I got them back to as close to new operational condition as was possible.

The Yaesu 400 series line up consisted of the FLDX400 transmitter, FRDX400 receiver and was finished off with the FL2000B amplifier. These 3 pieces of radio equipment looked beautiful in the flesh and were wonderful to operate. Taking a good 15mins to warm up and become stable you couldn’t rush getting on air. This line up was my favourite by far even though they weren’t as good as the 101 line up.

Above the 400 series is the later FTDX501 transceiver with matching speaker. This was a great radio in its own right but, not as much fun to operate as the 400 line up. To the right of the FTDX501 is the matching Yaesu Microphone for the 400/500 series. This mic is incredibly rare and I had to visit many radio swap rallies to find it, worth the effort though.

Top right you can see my old SWL receiver, the great Drake SW4A. I never had a Drake line up as they are quite rare in the UK but, it certainly would had made a great addition to the station.

Finally this is a photo of two friends of mine, Steve Thomas M1ACB (Current General Manager of the RSGB) on the right and Andy, G6ALB with whom I spent many hours sending and receiving morse with to get our Class A licences. We had a fun day together operating the old radios and taking it in turns to handle the pile ups!

More soon …

Not so spooky October

Β Well October flew by. I didn't get around to half of what I wanted to.


I worked some FT8 here and there. I qualified for a few awards from the FT8 Digital Mode Club. I got the Worked Prefix Award for working 100 prefixes on 40 meters. I got the Worked All South America Bronze award for working stations in all 10 South American Countries. The Worked All Members 100 Award was issued for working 100 members of the FT8DMC. I got the Worked United States Station 200 Award for working 200 US Stations. And lastly I got the Costa Rican Station Award for working 3 Costa Rican Station.

I was also able to attend a yard sale and acquire some equipment. I picked up a few sections of tower (with two toppers) along with a Alliance HD-73 Rotor (need to find a control box). Included with the towers was a 2m vertical and what I believe to be either a 2m or dual-band(2m/70cm) beam.Β 

Equipment wise I was able to get the following:Β 

    • Heathkit SB-401

    • Heathkit DX-40 Transmitter
    • Hammarlund SB-600
    • Knight Ocean Hopper
    • Signal Corp BC-342-N (Farnsworth Television & Radio)
    • Bendix Radio Type TA-12C Aircraft Transmitter
    • (2) Midland 75-764B
    • Uniden Pro 510XL
    • BIG BOX OF TUBES
Equipment, Antenna, Tower

I need to go through all of the equipment and see if it works or what parts it needs. A couple are in a little rough shape. Looks like most will need new tubes. One needs new knobs. I think the 401 needs crystals but that's as far as I've gotten 😁. I haven't even looked through the box of tubes yet, that's going to be a chore.


Looking ahead I've found a few things to update my room a little and picked out paint colors so hopefully I can get that started soon. Ham wise I'm thinking about trying to work the ARRL SSB Sweepstakes this month. We'll see what happens.Β 


Well that's all for now! Kinda short, but there's pictures this time!!
