Despite my stroke leaving me giddy - using a soldering iron is now very hard - I am back on 630m WSPR TX (20%) and all reports would be really appreciated, even if you are just a few km away! My ante

Sorry Ian. No I did not hear you. Since then I have been on 630m WSPR, but no reports yet. 73s Roger G3XBM On 10 October 2017 at 20:05, <[email protected]> wrote: Hi Roger Got a decode from you on

Well, there is no way my setup will ever compete with G3KEV. However I was amazed to be received by anyone last night, let alone in Norway! My setup is unbelievably bad and is just the coax to my 2m

Hello RSGB LF group.   Was there something special arranged on MF last night because, using 470kHz for the first time seriously, I captured a phalanx of WSPR stations, quite a bewildering number. Is

Back in the spring, my brother managed to cut my 630m earth-electrode "antenna" whilst staking a tree for me. I have not got around to repairing it. If the weather is good tomorrow, I might get the e

My earth-electrode "antenna" for 630m has been repaired and the secondary antenna current reading on the Marconi has gone from 17uA to 22uA using this as an additional ground.  It remains to be seen

Well, I have now strung a couple of radials across the grass and connected an(additional) ground outside the shack. Interestingly, the antenna current is no higher - I was expecting this to read high

Best of luck Martin. Thank you for trying. Just switched to 630m WSPR from 10m FT8 RX. The latter has been amazing. 73s Roger G3XBM On 16 October 2017 at 16:15, Martin Evans <[email protected]> w

Overnight I was keen to see if the addition of 2 radials and an additional ground outside the shack improved my results on 630m WSPR. Well, I am not sure.  You will recall my ERP is around 10mW. Over
