  1. Hi Guys

    Just listening to the podcast and Pete's QSO on the National SSB. My first RX was a Heathkit HR10B in 1976 and bought a used DX10(?). In 1982 I left the hobby. Ten years ago I re-entered the hobby and joined the local ham club. One day I came across a HR10B on Ebay, The price was reasonable and I bought. In 1982 I had sold the HR10B but I couldn't find the manuals at that time. I came came across those manuals and wouldn't you know it, the recorded serial # I scribbled on the manuals matched the ebay purchase serial #. Wow I was blown away and what are the chances?

  2. Ken: We would proclaim: "TRGHS" The Radio Gods Have Spoken. You were meant to have that rig and get it on the air. Thanks and 73 Bill

  3. Another great podcast. Thanks gents.

    For berets, I was in the Army when they stole the black beret from the Rangers and forced us POG's to wear them. Worst headgear for working in a motorpool in the depths of a Texas summer. Dress uniform maybe, day to day no joy for the working solider.

    Suppose I should dig mine out for that giveaway.

    Very cool find Ken! I agree with the grand poobah, TRGHS.

    Stay radio active.

  4. Hi, Bill and Pete -

    I just wanted to thank you for playing the Vintage Sideband Net preamble/manifesto on Soldersmoke 210. It made me wish, for the first time in 50 years, that I still had my Eico 753 transceiver. Believe me, that feeling passed *very* quickly, but I retain my admiration for the men and women of the net, whose passion for flaky old SSB gear is infectious.

    73,
    Bob, W6BP

    I wasn't a radio ham when my mum took me to the doctors, just an electronics obsessed pre-teenager who couldn't get to sleep on a night. My mum believed that all childhood ailments were self inflicted and grid bias voltages were keeping me awake. You would thought that since my mum had given birth to three lads, she would have realised that most young males are pre-programmed to sleep in the morning, not at night.

  8. Bill & Pete,
    Great episode! Even down under we were inspired to seek out the right safety wear for home brewing. It turns out that the protective head gear is widely available here. http://blog.marxy.org/2019/03/the-right-hat-for-soldering.html (Note the HRO dial by the way).

  10. Bill & Pete,
    As usual, I enjoyed your latest podcast. My first station, back in 1958, was s home-built CW-AM transmitter and a Heathkit AR-2 receiver, which was pretty useless. I soon upgraded to a US Navy TCS receiver (made by Collins!). It only received up to 12 Mc/s so I had to build a converter for 20-15-10. It was pretty wide, even for AM and I added a BC-453 Q-5er. Later I got my hands on a Collins 6 Kc/s mechanical filter and installed it in the TCS. This rig was used until I started on SSB with a Heathkit SB-101. I still have all these rigs, except for the Q-5er.

    Hum... Magneto-striction? ... that reminds me of my 18th as an aprentice on a naval electronics firm, (in here in northern Portugal Leixoes) .. it was used in the echo-sounders transducers aboard wooden hulls (allways at theport (left?) side & a few probs that where caused by cavitation bugging the "ultrasound" freqs used... I am 59 now... an air-head or petrol-head , or propeller-berret kid -
