I made the video above to show postential builders how useful our Direct Conversion receiver really is. Late in the video (starting at 11:17), I heard a station calling CQ. It was N4QR. A check of QRZ.com shows it was Bob Null. Here is picture from Bob’s QRZ page:
Check out the old general coverage receiver and — wait for it — the homebrew thermatron transmitter. TRGHS.
Google led me to this amazing video by Stever N4LQ that describes a book that N4QR put together on how to build thermatron transmitters from Junkbox/Hamfest parts:
Steve N4LQ is in contact with Bob N4QR and asked him which transmitter he was using when I heard him. Bob said he thinks it was his 30 watt 807 final transmitter.
Thanks Bob. and thanks Steve!
Very nice sounding Rx, Bill ! And so you can give N4QR a proper HB to HB call on CW, may I suggest a Tx that would nicely with that? Try a 40 Meter MOuSeFET, and they will never call you an appliance op (or a “drifty op”) again. ~20 watts CW is so effective.
FB RX Bill! Btw, the correct pronunciation of diplexer is die-plexer, not dip-lexer. Like dipole, diode etc. 🙏
