Thanks John! everyone assumed it was okay but it's good to hear it officially. Now we can re-assure the stations in other countries that they can work us cross-band. ....on with the good work! Cheers

Hi Lubos & LF, The "dots" I see, hear are around 502.6 and 505.6 with occasionally a much weaker set at mid way between. I don't know what produces the signal. Occasionally there is a long dash of a

Hello Jim & LF group, Thanks for the report. This is the sort of thing I wondered about. Up to 18:36 the 5W / 20mw ERP signal was readable but dropping another 7dB and it was below the noise floor. I

Hello LF, It is normal, polite amateur practice to a) listen for a few minutes and b) send a signal such as QRL? when selecting an operating frequency. On 500kHz itself this is rarely a problem, as b
