Thanks again Dave and Alan, I've spent a few more hours on the F/S meter today and still have not found the problem. I can blow with a drinking straw on any component and there's very little output c
LF, I've just rebuilt PA0SE's field strength meter (LF Experimenters' Handbook), modified for use on the 500 kHz band. I've followed the published circuit as near as possible considering available co

LF, I've nearly completed my new PA for 500 kHz and have now managed to stop destroying FET's. Unfortunately I have an unusual problem in that the heatsink cooling fans are going U/S. I have used 24
LF I shall be calling CQ tomorrow morning: Saturday 29th from 0800 GMT using CW on 136.5 kHz.and later using QRSS on 137.7 kHz. I am testing a new loading coil and so any contacts or reports will be
Yes chaps your ears did not deceive you. Andy is operating on 500 kc/s today and maybe tomorrow. A call on the band tonight may rouse him. He has a 150m long and 20m high aerial but is only running 5
Hi, Dennis and Chris. I checked your relative signal strengths during your QSO on 500 kHz this morning, using the Wandel & Golterman SPM-30. M0JXM was averaging -74 dBm, and G3XIZ was averaging -62
LF It was a red-letter day today as I achieved my 1000th QSO using 600m. This includes 72 cross-band contacts, virtually all of which were 600m / 80m. Rog GW3UEP was my 1000 th QSO with runners up G3
LF, I was receiving good signals from OH1TN last night: 2250 Z - 137.7 kHz - DFCW(3) - 'O' - in IO 92 UB I replied to his CQ's but my aerial current was low due to snow. 73 Chris G3XIZ
Many thanks for all the contributions and suggestions. I have been reading them and trying to understand but I am no 'boffin'. Basically I have a 'decent' PC and appear to be receiving WSPR ok. My ri
LF, Is there a fairly simple interface unit which will enable me to transmit WSPR signals using my home built MF TX ? My TX has a VCO / FSK facility but no audio inputs. I've had a search of the inte
LF, I called CQ on CW for hours over the weekend. There is an oasis of activity locally with M0JXM and G7NKS often transmitting. I work both these gentlemen most weekends. Unfortunately my local nois
LF, Many thanks to Mal G3KEV and Dave G3YXM for the CW QSO's. Thanks also for all reports and I'll personally respond as usual. Conditions seemed good and the band quiet so even my modest 100 watts w
Dave / Chris / LF, Thanks for comments and reports. I'll try to keep to the following schedule this evening, unless called: GMT MODE QRG 18.00 - 18.20 CW 136.5 kHz 18.20 - 18.40 RTTY 137.5 kHz 18.40
LF, Yesterday evening I was QRV on 136 / 137 kHz - CW, QRSS and RTTY. I had no contacts and received no reports. I shall be on LF again tonight from about 19.00 GMT should anyone care to try for a QS
LF, I copied PE1GRL on CW at 19.50 GMT, QRG: 503.500 kHz. Report: 5 6 9 I called him but had no reply so presumably he's in beacon mode. I've not heard this one before. 73 Chris G3XIZ IO 92 UB
LF, WSPR activity on 500 kHz appears in the doldrums with only G4JNT and G3ZJO regularly transmitting in Europe. However EI6IZ spotted WD2XSH/17 on 13 occasions last night at 4594 km with s/n averagi
