Hello Group, are there any experiences with extendig the TX range of these Kenwood radios down to MF and LF? Long time ago IŽve already done the usual extensions for general TX coverage within 1.7 to
Hi Tom Nice array of rigs I also own a TS50 plus a TS690s quite good on the RX side at M/LF the TS50 lacks the RX filtering of the other rig. My suggestion is build an GW3UEP TX but drive it with red
Exactly. There's no technical reason for WSPR to require a "linear" transmitter, and to modulate it via 'audio' from a soundcard. It's a frequency shift keying mode with no amplitude shaping (unlike
Hi Pete, thanks for the splendid idea - obviously I didŽnt see the wood for the trees, all the more everything needed for this approach is already in use here! IŽve a switchable devider by 10 for MF
Hi Tom, What i don't understand: We've already been in QSO on LF and MF. So you are already QRV. So why do you want to build such a complex, heavy, big and power consuming system to drive the PA? I w
