Hi WM6, et al. I have an EMFAD which was designed to receive 44-142khz from the "submarine" tx's, and we all know that the old Loran and Omega stations have shut down, leaving the 3 here in the USA, which transmit at around 24khz. Fine. So, first I had the EMFAD receiver altered (caps) to receive a very selective 24khz signal, and then I had a small tx built (North Country Radio) that supposedly puts out 1 watt. I have attached a 12 mtr x 4 sides loop antenna (18 guage copper stranded wire) to it but it does not produce enough power to give steady constant results on my imagry. The side closest to the tx is always much stronger, so not a reliable image is produced when I do my grid survey. Any ideas? I would have thought that the tx in Cutler, Me would have been strong enough to reach down here in south Texas, but it doesn't seem to be. TIA for any advice.
Also, the manufacturer uses similar tx in his new model, the "PRO" and he advised me on the antenna design.
