    20-Meter pipsqueak transmitter! 1-watt output

    So I got bored yesterday at work (I work at home) so took off 2 hours to
    go out in the shop and put 1-watt on the air at 14.318 MHz (yeah, CW in
    the middle of the USB portion of the band - but hey - I have hundreds
    of the crystals laying around).

    Has a little chirp, but I moved the output link on the tank coil around a
    bit and got it pretty tamed now. As long as I don't run the transistor
    too hard (16v right now) it holds pretty steady.

    I actually made ONE contact - OK - truth is we had a schedule arranged
    and he's only a few miles from here, but what the heck! Not like I'm going
    to get a lot of answers to a QRP CQ in the Phone Band!

    :)

    Very cool!
    All the world’s a stage, but obviously the play is unrehearsed and everybody is ad-libbing his lines. Maybe that’s why it’s hard to tell if we’re living in a tragedy or a farce.

    Yeah, but watch out for the RF burns.

    Believe it or not, I found that great key as "New Old Stock" brand new in the original
    box at an antique store somewhere in rural Ohio for $25, a number of years ago. My
    first thought was "wow! that will fetch a nice price on eBay!!" - then I brought it
    home and tried it out... OMG! It's my favorite hand key of all time. It's terminated
    on a short RCA-terminated cable that mates up with my "Key interchangeability" cable
    system so I can use it with any radio in the shack. SO glad I didn't sell it. The base
    I bought on eBay for $13.95 including shipping from an OM who makes those in his
    his garage. VERY nice quality base.

    I'm impressed! Notice you won't get any nay sayers here like you did the "other" place. That coil form looks very familiar to me for some reason! :)

    You have a very good eye my friend! Yep - that's one of those. Saving the 3 NOS Hammarlund forms
    for another project maybe in Spring or Summer - a band changing open chassis transmitter for 40, 30
    and 20 meters CW with a 2E26 final.

    Let me root around Ye Olde Junque-Box and see if I have any lower 14MHz HC-18 rocks. If you wish to duplicate that on 30 meters, I know I have a few in the 10.140 region.

    Really? I'd happily trade ya for a fundamental rock on 30 meters... not for THIS transmitter,
    but for a much better one. 30 is a fun CW band and I'd build up a very decent RF puffer.

    Let me know via PM or email
