Hi all from another builder

Post by Juremm »

Hi all,

let me write few words about me. Being in the HAM radio from my high school, firstly with CB, later as a HAM. At that time I did build/modify many devices. So every CB radio that I've got was modified to have more channels etc.

Now electronics is giving us opportunities for building even more great stuff. As such I've made FM VHF or UHF radio from DRA818 module, radio is called the Weekender - name was given because in one weekend anyone can build it.

Also I've been into simple FM walkie/talkie modules that have impressed me. These modules can be programmed from CB to VHF, UHF and PMR frequencies and work great - considering 10 mW output power of course.

Have also build mcHF by M0NKA, Chris and my recent project was uSDX by DL2MAN, Manuel, both working on a home brewed Fuchs resonant antenna. I've build QRP Fuch resonant antenna tuner and recently I've built 100W version of it with a huge roller coil, both variable capacitor and roller coil being remotely controlled from my shack 8)

Beside that I love programming AVR microcontrollers, I program them mostly in Bascom-AVR since it's much more user friendly than any C language - hope that I will not enter into "religious war" with this sentece :D

Programming AVRs has opened (at least to me) many doors to any CB or HAM project that I could think of.

That's all about me, glad to be here.

Best 73 de S52CQ, Jure

Well in this case I am afradi the mod that's been done is not working. Talk to the guy who's done that mod and let him fix it. If that's not possible you can always seel the rig and purchase another one with FM included. But I guess it's a shame to sell such a fine rig, I'd love to have one, although I've got plenty, but cobra 148gtl is a legend 8)

Stay safe!
