looking for rx/tx transceiver.
|
david todd
found this group and am looking for the rx/tx assemble that has multiple bands. used,or unbuilt.
Hopefully the new owner will combine some of this to make an all in one transceiver with a display possibly? and a raspberry pi or alternative similar inside a case with display? wishfull thinking? 73 David ac9xh |

There is a reference on the internet to someone who did just that. There are 3 filters in the rxtx board. The low pass filter for tx, the bandpass filter for receive, and a filter on the output of the oscillator before the mixer. You can make the board multiband by, either making plug in boards for each band, creating a band switch with filters switched for each band, or making a board similar to the low pass filters on a linear amplifier to have relays switch the filters. I do have plans for a new enhanced design and will be working on it over the next year or so. I am hoping the new design will work from below 2200m to above 2m.

David, I have a number of unbuilt kits. I will check to see if one might fit your request and get back to you by the end of the day.

Hello David,
I was heavily involved in the MOBO project using the RX-TX 6.3 modules. Was a wonderful project. You know a current radio that uses the RX-TX radio is the SDR CUBE. It is a wonderful radio you put together. I have two complete SDR CUBE radios that are a joy to build and operate. Look up MidnightDesignSolutions. I am only a very happy customer, builder and have NO interest in the company. Let me know if you would like pictures or information… Chuck WA6LTV On Tue, Feb 28, 2023 at 1:10?AM david todd via groups.io <ac9xh= [email protected]> wrote: found this group and am looking for the rx/tx assemble that has multiple-- Thank you, Chuck Nolin WA6LTV |
