I am very sorry to read that Jack passed away, thats a very sad news. I will never forget, when I operated CQ160 SSB in 2013 it was 20:30 local time when he called in, I could not believe his S7 sign
Now its getting really silly OK - I think I've got a good start on the list......................who knew Joe Taylor was the Antichrist?? Things that will kill the hobby.....................in no par
No wonder, imagine how many robots are active on all bands in parallel per station. 1.5 million hits for FT8? WOW! _________________ Searchable Archives: http://www.contesting.com/_topband - Topband
1) you need a modern(relatively new)station 6) you like to be bored by doing ham radio 73 Peter The FT8 comet is back: 1) It's still legal; 2) It's still not mandatory to use it; 3) It only 'wastes'
If my 160m receive would be as bad as with any web sdr I would not contest on that band. Which web sdr is used from Eastern Europe? 73 Peter Serious problems for topband are the use of WEB.SDR. Espec
Of course I understand the topic. Web sdrs have the worse receiving capabilities. I see no reason at all to use one. But you did not answer my question concerning the sdrs. Please do, if possible wit
Those are exactly those deaf sdrs I mentioned, just useless. But tell me how exactly will you know who is using them? 73 Peter --Original Message-- From: Topband [mailto:topband-bounces+dj7ww=t-onlin
Hi Frank, I just simulated a T vertical 50m away from my 38m high 3L 40m yagi with EZNEC. Pattern and gain did not change on the yagi when it beamed 90° away from the yagi. Only when I turned the yag

If a 40m yagi points towards an 80m or 160m dipole in its neighbourhood the yagi pattern will be ruined as well. 73 Peter Hi Paul, A little modelling will answer the question more completely and accu
I have used LDF4-50 and LDF 4-75 by RFS for phasing lines on HF bands. They did as expected with 88%, however on VHF/UHF I would measure how they behave. 73 Peter Hi all, I wonder whether anyone has
LCF 4-50 is relatively cheap here, I pay 2.80 Euro per meter for LDF4-50 and 4,84 Euro/m for LCF78-50. It can be buried and is resistant again mice and bird bites, no chance to be drown and it is ver
There is nothing special, a 50 feet high dipole has at 25° elevation angle the same gain as a shortened vertical over lossy ground or with just a few radials. 73 Peter Well I've said it dozens of tim
I think most skimmers on the RBN are wide band skimmers on small antennas. As web sdr receivers they only hear the stronger signals. 73 Peter --Original Message-- From: Topband [mailto:topband-bounce
I think there will be much more not discussed yet concerning ground conductivity. What do you have to offer? Peter, DJ7WW I think it's about time for this discussion about ground conductivity to come
Bypass the rotor with thick ground lead from the rotating pipe mast to the tower, use ceramic bypass capacitors on the pot contacts and MOVs or low voltage spark gaps to ground on all lines to the ro
MOVs and shielded rotator cables are also recommended in the ARRL antenna book 20th edition and I use them for that purpose for decades. Andrees rotator cable canīt be laced to the tower as it is a t
At my place the two beverages I am using, 160m to NW, 120m to NE are only good for decent signals. The real weak ones I can only copy with my vertical which is an elevated GP (top loaded tower) fed a
Itīs amazing, the probably envious stations always suspect others with their better antennas and perhaps better operation to use web sdr. 73 Peter --Original Message-- From: Topband [mailto:topband-b
I used a dipole at 103ft and an elevated GP (top loaded tower) fed at 70ft with full size resonance and two elevated straight radials for the last couple of years. Foreground is sloping towards North
