Hello LFers I had previously described an antenna for 500kHz on this reflector which used an HF quad and its feeder fed against ground using a suitable ATU. The calculated gain of this antenna is aro

When I heard John's recording of my signals with a 10Hz AF filter I was most impressed. My own view is how various bits of hardware work depends a lot on the listening environment. On 73kHz the recei
How about a very short resonant quarter-wave helix? Peter, G3LDO Does anyone know if the e-field probe can be adatped to HF frequencies? Some of you will know I am a member of Amsat and we have an op

EZNEC 5 shows the 1200 fence (3ft hi) antenna to have remarkable receive properties If terminated with 400ohms it produces a polar diagram not unlike a 3-element Yagi with a maximum gain of -17dBi an
I'm hearing G3LDO calling CQ on 501.8 at 19:52z Can't seem to raise a response though. Perhaps my shorter antenna is a dB too short? Hi John, I heard a signal but it was too weak to read. I will try

Hello LFers, I had a xband QSO with Joe, VO1NA at around 2230UTC this evening. My QRSS3 transmission was on 501.193kHz. I listened for Joe on 7000.5kHz. My report was M and I had to repeat his report

I will transmit QRSS3 on 501.190kHz this evening and listen on 3540kHz. If you want a cross band QSO just call; you don't need to wait for my transmission to end. I can switch to CW if my signal is s
John & LFers, I endorse Gary's comments completely. We have had to endure e-mails from the source you mention since the early days of 136. The best way to treat them is to ignore them completely - tr
