    Great news about 630 and 2200m. I hope to hear some signals from across the Pond this winter then.
    I've been constructing a 630m station consisting of a QRP Labs Ultimate 3S tcvr kit for 630m for digital modes (WSPR and JT65) and a 300W amp by G0MRF. Total cost was probably under £200 ($260). I have a 40ft vertical wire up in a tree with a 50ft top. Ground system is elevated about 8ft up with a few radials and above all two tin sheds! Intention is to put the loading coil near the top of the vertical section. I have a similar arrangement for 160m and it works well into the States with 100W in Winter, so there's just a chance I can do it on 630m. Just building a variometer at the moment. I think the challenge is trying to tune the antenna. I haven't found an antenna analyser that works below 1MHz yet. Might take some time to get it all working efficiently.

    Sounds great Randall:)

    These bands need additional RX/TXs than the HF/MF transceivers, but now you can be the band master on all of 'em:)

    73 and best DX,

    Icom 7300 specs - 0.030–74.800 mHz. I haven't heard much down there. I will be listening but i have no plans to transmit. Maybe DX Summit can add the band for spotting! If I hear anything I will send out reception reports like the SWL gang.

    it is already on dx summit: look just below VUSHF for a title called LF and you will see the choices 137khz and 472khz. Hope to see ya on the band :)

    if you just want to play around ,in addition to K3/K3s Some of the old communications type receivers like the yaesu FRGS go as low as 150khz and have SSB and CW ,For a transmitter you could use something like AA-908 amqrp "antenna analyst" . At that frequency you probably would want to build a PA for it. The real issue is the antenna , at frequencies that low your probably looking a loaded short vertical/L for best efficiency ,the ground losses for most of us will be horrendous .

    Randall,
    You could do all that google stuff - or- if you just click the detail tab on your QRZ page you will find both your lat long and your grid square. And it won't take more than 30 seconds.
