Used AN-1 with Sony ICF-5900W in downtown Washington, DC, and the results were excellent. Ditto out in countryside in Reston, VA.

That was back in the 1980's with far different propagation conditions.

So, I am looking for a used AN-1 for my Tecsun PL-600, because propagation is volatile and I believe AN-1 will help me along, despite all.

Example of effectiveness of AN1: Early morning East Coast time, I could consistently pull in Voice of Vietnam domestic on 15010, which I know from my Vietnam days was using ERP of 7.5 KW. So, all things being equal, I KNOW AN-1 works and want another one.
