Subject: Re: FT-5100 squelch
Hello Joe, thank you for using Yaesu product. You must do some little =
tuning and calibration for your squelch as follows, 1) Tune to the =
center of the VHF band, and inject -15-dBu RF modulated with +/- 3.5 kHz =
deviation of a 1 -kHz tone to the antenna connector, =20
2) Set the SQL control to the 10-o'clock position, and =
adjust VR401on the IF unit so the squelch just closes.
3) Retune the transceiver and the RF signal generator to =
the center of the UHF band, and with the same injection level and =
modulation as for VHF, adjust VR402 so the squelch just closes.
You must at least have a good calibrated RF generator. Please feel free =
to contact us for any additional questions. Best regards,

Can you provide the procedure or location of the adjustment point =
for the FT-5100 squelch? Stations that are too weak to show up on the s =
meter are breaking the squelch, even when turned up completely. This is =
very annoying when scanning. Thanks.
