Congrats Finbar EI0CF you've been 15 dB over noise here most mornings this week also via MB7LF. Considerably stronger than you used to be. Called you but only have 100 mW tx so forlorn hope. OH1TN on
At 73/136 khz how far away from a wet tree do you have to be not to see any RF loss? At one extreme if your ant runs through it you will lose a lot; at the other if it is several kms away you won't l
Can't help feeling some of the reaction to MB7LF is premature. It isn't a fixture; it's experimental only; you don't HAVE to use it even if you're within range; and if QSO's through it are thought to

I don't know if this is the same transmitter, but I have been copying G3JKV all afternoon on 136.4 at rst 569, sending nothing but random letters with the occasional callsign, and not apparantly list
Thanks to excellent work by Derek G3GRO the GB3LF repeater is now on the air from Crawley on 144.9875 MHz. It's relaying the entire 136 kHz band as an upper-sideband signal. The 136 antenna is Derek'

Ron, Audible here most weekend at R2 S2. Would have been better except for heavy QRN. On Spectran clearly visible and readable. Dist is 310 kms. Walter G3JKV IO91UF 5113.3N 0019.5W

This big/small antenna business : Let's get this straight - what matters is RADIATED power not how big the antenna is. Radiated power is the ONLY determinant of how far we get . An antenna is only a
Mal, A lot of us would welcome your "critisism" far more if you stuck to technicalities and cut out the cheap sniping at anyone who doesn't see things your way. Walter G3JKV
Besides 132.24 and 146.40 kHz signals, now I´m shure that there´s TWO DATATRAK signals on 146.4KHz. One is very strong here (now peaking 15dBuV) and the other is weak. Different timings btw. Tomorrow
Thanks to DJ8WX, G3JKV and DL4YHF for the encouraging reports! G3JKV in IO91UF holds the record, 1120km/mW or 700000 miles/watt, hi 73 Johan SM6LKM Interesting! Is that RADIATED power or DC input? My

If you measured the bandwidth of an entire antenna system, (earth-tuning coil-antenna), then measured the bandwidth of the coil itself alone, could this be used to get some idea of earth losses? Coul
At 2320; G3AQC 72 401.3 1 Hz shift -9.3 dB G3LDO 72 399.45 -10.0 dB Only 0.7 dB difference here so if one is seen the other should be as well. Go to it, lads! Walter G3JKV
Laurie, My congrats, too. Might like to see what your sig looked like "locally" - I'm only 63 kms from you. Taken this a.m. just as you switched off at 0712. Time span of graph about 2 hours. Spectra
Would the steerable attenuation be more useful for nulling out interference than the gain itself? Nick Hi Nick, In theory, yes, but there are multiple nulls of varying depth and you probably don't kn
