David, You might try some web searching on the subject, as there is some material on calibrating receiving setups and making field measurements. Here's one possibility: http://www.w1tag.com/LF_FSM.ht
Jim, maybe a method 3: Measure the field strength of a strong TX (eg. DCF39 for 137kHz). This can be done using a small calibrated RX as describe by PA0SE. Based on the you can calculate the antenna
David, There is a whole lot of stuff written about determining ERP involving a lot of maths. The most accurate method is to measure the actual field strength. These methods are described in 'LF Today
Peter, As an interested observer from the other side of the pond, how do you determine that you are close to the ERP limit?? I'd be interested in knowing as I am trying to do some pro-bono work for t
Hi Jay, I will be sending a beacon signal QRSS3 on 501.1kHz until 2330z. I have modified my old PL519 TV sweep tube transmitter which ran about 60 to 70W. It now has two PL519s in parallel running 12
Jim, Thanks very much for the explanation it's very helpful. Too bad there aren't very many calibrated receivers and antennas. 73, David Weinreich WA2VUJ/3 >>> From: "James Moritz" <james.moritz@btop
Dear Jim, David, I have been successfully using a variant of the second method, which works by comparing received voltages of a strong distant transmitter (eg. DCF39) from the transmit antenna under
Dear David, LF Group, There are basically two ways of determining ERP, briefly: Method 1 is to calculate the radiation resistance (Rrad) of your antenna, which can be done using various text-book for
