Hello All. Your comment about your antenna maybe operating like a LOOP is probably correct. I would suggest it is performing like a grounded quad. Similar systems used on 160 and 80 metres where one
Hi All. Bob/ZL2CA in a recent message makes the same observations about grounded dipoles ie grounded loops in use in NZealand as I did in my experiments. Avoid such antennas if possible especially on

No Windup. Its a reality if you need to use LMCW and Small Loop Antennas and Lemonade bottles for coil formers for local qso's its SYMPATHY you need. I strongly believe that the noise on the Rugby 73
Hi all From statistics available the only amateur stations active on 137 khz in the UK capable of making a two way qso across the atlantic are MM0ALM/G3KEV/GI3KEV/GI3PDN. The statistics are based on
Dear all, Assuming that we're sticking to 1W erp then what does it matter how big the antenna is as long as the power is sufficient to give the required erp? There is a big difference in the radiati

Well, that's the point I was trying to find out. I wondered whether I could calculate my ERP from your graph, and plainly I could not. But is this Vaino's theory, or something else. If we could sort
The best way to find out wether we can cross the pond on 136kHz is to try it. What I have in mind is a transatlantic test, similar to what we did last year in cooperation with N4ICK, but with a much
There is so much more needed to built a BIG vertical than just the will to do it. A stable big vertical tower costs a lot of money (at least they're not for free in Belgium), the authorities need a
If you have ever wondered why you only get a signal report of say 429 when you are giving 579 it is because the station is transmitting on a vertical and receiving on a loop. It is not a reciprocal s

I'm really impressed by all the calls and I would like to join this funny game. But I have only one call and I don't know from where you got all these nice callsigns. You get a good selection of cal
That looks impressive but these calls are mostly around Europe, one day trips. There are only a few that are DX. I did not include my one week trips around europe, although I do operate /M and /P on

I agree with Steve. Besides, I suffer from astigmatism myself. Yes, there is a big difference between 1W ERP from a small garden antenna and 1W ERP from a 1000ft tower ;-) It's like comparing the pe
