Re: CW filter
Thanks, John -- I'll give that a try. I have a lot to learn around AGC and
gain controls still.

Re: CW filter
Suggestion for? CW and lack of or too much AGC
Especially useful for noisy band conditions
Disable AGC
Turn RF gain full CCW (minimum)
Turn AF gain to 3/4 max
Advance RF gain for your listening

Re: CW filter
Thanks, all, for the responses. Yes, this is for a FT-857D. They are hard
to find !
Regarding the DSP, it performs well, but at the AF level. You can dial in
the digital bandpass filter nicely, but

If my stolen FT-857D is parted out the 500Hz and 2300Hz Collins filters will be for sale.

Re: 857D pulling 2.9 amps at idle and the PLL unlocked. Help!
I don't think so, , usually insufficient current flows, due to the extra series resistance of a bad connection .
Check ohms law. A bad connection will cause high volt drop across it, perhaps that was

Re: 857D pulling 2.9 amps at idle and the PLL unlocked. Help!
Well first off if the radio was new and had not been messed with I would start by going back and removing the filter you installed, I assume you did not check the unit out prior to that, also while it

If you're going to all that trouble, why don't you just buy an ATAS so you can automatically tune it?? I replaced Hustlers after 50 years on my mobile and wish I had done it sooner!?Ron Jakubowski,

857D pulling 2.9 amps at idle and the PLL unlocked. Help!
Hi,
Last year, I bought a used FT-857D from a gentleman. It was new in box but sat in a closet for 15 years.
Today I turned it on and heard the relays switch on and off a bunch and saw the frequency

Re: WANTED: Yaesu TCXO-9
This is a guess on my part as I've no interest in delving into the "how it
works", but I'm pretty sure that the TXCO improves the stability of
frequency generation circuits, I do know that for time

Re: WANTED: Yaesu TCXO-9
The issue with the Chinese TCXOs is that they are actually programmable PLL oscillators and have more distortion to the waveform than a single crystal would.
This means that the RMDR or mixer noise

Re: WANTED: Yaesu TCXO-9
You can get a knock-off from Aliexpress, probably not as good as the Yaesu
one but I'll bet better than the original one that came with the 857.

SRI to ask a silly question.
What does the TCXO effect to?
I understand it may stable the VFO QRH but so what¡¯s good with it?
