Re: CB to 10m Conversions
|
Nice!!!
t leaast i know im not the only one converting these rigs. Yes 10 meters is hot. I was running Cw with about 1 1/2 watts and making contacts. I want to build a fm board so i can run the repeaters on the top end of 10. Am has ,in my own opinion ,been active on 10. seems alot of ops been re living the good stuff, finding out the quality of a good AM transmission.
My uniden grant xl only needed a crystal and peaking, but i prefer to have it wide open,so im going with the si5351 and arduino since i have several on hand. oled screens are fairly easy to connect but im wanting to have a bigger screen. Im going to remove the channel switch. Im also stripping down one of my 10 to 6 meter transverters so i can kick it in with a switch.hoping i can fit it in the case, if not i will obtain a new Plastic project box for it.
I remember back in the day, the hygain boards with the ploo2 chips or the uniden 828? might be wrong about the number, but you could pull the leggs that were grounded and add some pullup resistors to give quite a wide swath of channels with a couple of toggles.

Hi David;
The subject (victim) is a Cobra 29LTD Classic. I built up a board with an SI5351, RP2040 Zero, OLED, and a rotary encoder to replace the PLL. The control program is written in MicroPython, which has been fantastic for projects like this. The radio will be used for 29 MHz AM, although it has good sensitivity lower in the 10m band as well. May have to get the third channel of the SI5351 to generate 455 KHz to serve as a BFO so that it can receive SSB and CW.
The circuit is really begging for a simple PC Board to be designed. Also, once all the hardware is in place, it's easy to add more functionality to support scanning, memories, etc.
10 meters has been hot lately and there's DX in the AM segment, A project like this would be great for clubs that might want to have a 10m AM Simplex channel set up for local chats.?
I still have to get the OLED installed --BEHIND-- the front panel. (hi)?
