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

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

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

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
