Digital VHF/UHF radios DStar, DMR, or Fusion
I have a DStar radio (Icom 5100) but I'm not a fan of DStar. It's not
easy to set up and if I don't use it for a while, I've forgotten how
to get it working again.
A local ham said DMR is the fastest

Re: Looking for a circuit design for bandpass active audio filter
Thanks.
That would probably do it but it's not just the board, it's a kit with
the enclosure, and I'd be paying for a nice enclosure that I wouldn't
be able to use.
I'd like to see his circuit

Re: Looking for a circuit design for bandpass active audio filter
Have you looked at a Autek QF-1 audio filter? I have one that I have owned for 30+ years. All solid state and work great. There are several of eBay right now for around $40. Time wave DSP-9 is a great

Re: Looking for a circuit design for bandpass active audio filter
Did some searching and found the site I mentioned-
https://kc9on.com/product/calf-cw-audio-limiter-filter/
Maybe that may help.
And the Vectronics kit I also was thinking about is the VEC-841k

Re: Looking for a circuit design for bandpass active audio filter
There was a kit that had the capability of user adjusted band pass . It was switchable. I built one, works well.
I think if you search on eBay for the "CALF filter kit" it might be what you want.

Re: Looking for a circuit design for bandpass active audio filter
There is one. Try "VEC-830 SSB Filter" I have one, but have not had the chance to try it.

appropriate to post here, especially since it's not a busy place at
the moment.

Re: FT-767GX front panel reassembly
I've not done it, but maybe just a dab of super glue to hold stuff in place before assembly?

FT-767GX front panel reassembly
I received an assortment of tactile switches so I can now replace the
power/SWR switch button behind the panel on the RH side of my 767.
I understand that putting it back together is a chore,

Re: 7300 with Ameritron 811H amplifier
You'll do fine on the 7300, but you have to switch bands manually on the amp.

Re: Looking for a circuit design for bandpass active audio filter
I do not know if the kit from Vectronics would solve what you are looking but it may be worth a try.

7300 with Ameritron 811H amplifier
Is setting a transmitter delay enough to have my 7300 work with my
Ameritron 811H amplifier or do I absolutely need an interface?
If the radio can work with the amp using a simple cable with RCA
