Re: Ideas for AM, NB FM Demod and CW filter board
|
Mr Farhan did a great job of designing the uBITX and keeping the price as low as it is.? I doubt it could be done, but I would like to see something along the same line that has NBFM? and maybe AM and a CW filter in it for less than $ 200 USD shipped.? Just wish that I had the skills to do things like this.
I had two reasons to get this rig.? One was to play and modify it, the other is to drive some VHF/UHF converters from the Ukrain that are selling for less than $ 100.??

I was discussing with Farhan on this topic for an add on demod board to add more versatility to uBitx.? CB radios often used a common chip for AM as well as NBFM receive. I enquired here and TDA1220 is available in mkt for slightly more than a $.
With the parallel XF mod maybe we can have an add on board with this chip and a 6 pole Cohn CW xtal filter. 2nd IF's now being 12MHz SSB, 10.7MHz + 455KHz for AM/FM and possibly 8.xx MHz or some other for CW.?
Guys what to suggest..
