Jim You were a good 569 with me in Devon. I had intended calling you again after you (and Peter) had finished with Dick, but a delivery van of kitchen furniture turned up so I had to go and attend to
..................I can't remember what that height was, but if it is exceeded the rules have to be observed, and include things like providing lights and notifying the CAA. Mike Grierson G3TSO work
........... maybe some morse lessons would be useful. No, what would be much more useful for some would be lessons in good manners on the air! For example, making sure that one does not call CQ bang
I was never lucky enough to see G6CJ's antenna circus, but I saw a similar demonstration some years ago given by Laurie G3AQC which was most interesting. Do you still have the bits and pieces and min
Super signals this morning, Saturday, on 72 KHz with my VLW lying on the ground as a result of an ice storm last week. Aural reports in 500 Hz B/W: Dave 589 - the strongest signal I've ever heard on
David, Not me on 73 KHz, I don't have an NOV! You were a good sig on 136 here in Devon, 589. Sorry didn't work you but spent part of week end re-erecting antenna and the rest mowing grass! 73, Tom G3
In message <[email protected]>, g3kev <[email protected]> writes Square wave generators/dividers and class D/E amplifiers are fine for small antennas and low erp but NOT
If you read the literature published by one of the researchers/experimenters of class D/E amplifiers, he states that if you push the amplifiers, which most amateurs do, and do not pay attention to th
Dear Larry and Dick I found a 0.5 A RF ammeter at a club junk sale which is designated 10A/8481. A quick continuity check showed that the thermocouple was OK. There are not many of these functioning
Larry Again, at a mobile rally (hamfest) I bought a box of assorted ferrite and iron dust rings. There were about a hundred, various colours and sizes all for about a quid! My method of establishing
This is a variation on the well-known technique of diversity reception - which is what the old AR88D receiver was for (D for diversity!) - used by commercial HF fixed stations for many years. ....and
Mike, Alan, Larry and all, Surely the AR88s would be used with an external combiner? I would guess that the D suffix probably indicates the receivers had the necessary interface to an external combin
Not all AR-88's are the same either. Some have the 915 kHz IF while others have the 455 kHz and I do not remember which have which.... Larry VA3LK Wasn't it the -LF version which had 915 Khz IF, beca
Hello LF Folk I don't know if Bob G8RW monitors this reflector, if so, apologies for disappearing mid QSO on 136KHz at 0715 Z this morning. We are having some strong winds and my antenna must have bl
Thanks Steve for the QSP and thanks also to Marc and Alan for reports. I put my 1100 ft long wire back up but it's even lower than before. Quite difficult dis-entangling halyards and wires from trees
Larry & all My 1100 ft horizontal long wire is made from 32 X 0.2mm thin wall PVC covered, 10 amp plain annealed copper wire, Arrow Stock No: 438095B, cost 30.42 pounds per 500m reel. Maximum length
Excellent stuff Peter and congratulations. Would be interesting to find out from Jack how much power he really is running. Do you think he might be audible on 'real' CW? (Computers are banned in my s
Hello all 600 watts of RF puts about 4 amps into my long wire so if Jack VE1ZZ gets 12 amps into his long wire, he must have 5 or 6 KW of RF! 73, Tom G3OLB
