John Kirby All Messages By This Member #53678 ?Quentin, et al,? You did not mention for what xcvr ???? 817/8 or 857 vs 857D? IF for the 857D AND at todays price of these filters you will be disappointed IF for CW the 857D's onboard DSP (es associated menus (tweeked)) out perform the crystal filters IF for 817/8 or 857 take a pEEk at stagger tuned external filters ?.../g/QRPLabs/message/113209... ?((/g/QRPLabs/topic/102251794#113209)) 73 73 74 John N3AAZ ps based on first hand experience with all the above

Quentin, K7DRQ All Messages By This Member #53680 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 the AGC will continue to act on things outside what you're hearing, causing flutter and cracking. Ken, I would like to take you up on that ! I'll email you separately. Thank you.

Quentin, K7DRQ All Messages By This Member #53682 Thanks, John -- I'll give that a try. I have a lot to learn around AGC and gain controls still.
