AA1TJ's Code Talker TX

LC Meter - a nice kit

Last night M0WKR (IO94 at 237kms) reported my 500kHz WSPR beacon bringing the total number of unique reporters up to twenty.

The 500kHz ATU

AA1TJ's "Code Talker TX" - all voice powered
Mike Rainey continues his work on purely voice powered transmitters, in which just the energy in his voice is used to power the RF circuits i.e. no batteries or PSUs at all. He's achieved well over 100kms on 80m this way using a form of CW derived by whistling into a loudspeaker to generate the energy needed. Here is an example of his signal received 109kms away. He can clearly be heard "keying" (actually whistling!) the words of "Mary had a little lamb" in CW.

A good evening on 500kHz QRPp

A 19th reporter on 500kHz
G4EFE managed to hear my WSPR beacon on 500kHz several times last evening (127kms) bringing the total number of unique stations receiving me to 19 now. I still have work to do to get over the 1000kms distance target.

500kHz - an 18th station hearing me

CQWW contest summary - 10m was great
With darkness falling now 10m is going quiet after an exciting 2 days. In the end, my 5W SSB and halo antenna worked 35 stations in 20 countries. DX from outside Europe was not workable this time but I was hearing CX, PY, ZS, 6W, etc so conditions were definitely not bad. Although there were a couple of stateside stations worked from Europe, I did not manage to hear them. The slight upturn in sunspot activity came just at the right time.
