Part Two

1) Our broadcast FM block. Blocks the very strong 88 - 108 MHz broadcast FM band, to stop SDRs/radios from overloading.

2) Another broadcast AM block. Similar to our AM HPF from your other thread. Has less blocking, but allows the VLF/LF band to pass.

Thank you so much for ID'ing these little devices. Would you recommend chaining your two filter blocks together to block both AM and FM signals? I have interference from both.He also gave me a 9:1 Balun. Should I use this with a random length wire antenna? Thanks again!

If you're only listening to HF, chaining the two together is fine.

A 9:1 balun could help with matching the random wire antennas impedance resulting in better reception.

Thanks again!
