I use 453s as Q-5er for the BC-348. My noise level is such that LF and VLF are virtually impossible. Might try a loop, again. But... truth told, many NDBs are long gone. I got many SWL cards for the Swan Island HH beacon. 2kw on 407kHz. Decom in 1972.

Subject: [MRCA] Vintage LF/MF Fun with my BC-453B

Hi Everyone

For the past 2 years I've been using my RBA receiver for vintage LF/MF fun, and have logged over 200 NDBs each year. This year I decided to use my BC-453B receiver. It's been recapped, and all out of tolerance resistors (sans one....) have been replaced.

Since early November, I've logged 52 NDBs. I'm hoping to log 100 this listening season (which runs through March).
