John and group

Thanks for the reports - I'm following the WSPR spot database.

Transmitter power is actually 400 watts but that is not a choice in the pull down box. Wasn't aware 
it supposed to be ERP. When the program originally came out a couple of us on 137 and 500 were using 
transmitter power so I've just continued that. ERP here would be about 40 watts.

If you're interested, info on the linear amplifier in use can be found at 
http://www.w1vd.com/9505MF.html . For non linear modes I use a combined pair of Class D amplifiers 
at 1 kW. Info on that amp can be found at http://www.w1vd.com/137-500KWTX.html .

Yes...500 kHz is quite a roller coaster as far as QSB is concerned - both on the long and short 
haul. Transmitted WSPR about a month ago and got a few reports from EU but seems interest has grown 
since then.

Thanks again to all for taking time to look for the signal.

Jay
