- Subject: Fix for popping squelch!
-
- From: N2AVN@WA2UMX.#ENY.NY.USA.NA
- To : RAMSEY@ALLUSA
-
- The Ramsey FTR-146 and the FX-440 use the same audio and squelch set up, which
- pops and clicks very loudly as it goes in and out of squelch. The fix I've come
- up with softens the squelch control voltage transitions and mutes to a great
- degree the objectionable popping.
- 1) break the land pattern from Q6 to pin #1 of U2 (FX-440) and bridge with
- a 1K ohm resistor.
- 2) parallel c-48 on wire side with a 2.2 uf cap.
- Try it you might like it.
- 73, Norm, N2AVN PS Also hv fix for low Pwr out frm 440.
