resistors and chokes so the pll mod for sure. thanks

Great thanks for the info was just curious about the kit. thanks

I know you can do the pll upd858 mod for extra channels. I see there was an expo Kit Q for the radio. I'm trying to find what that kit did. Was it toggle switch kit Was it an Expo 100 Kit with crystals if so what was the frequencies of the kit? thanks

Back in the day Jan xtals- Tennessee xtals and Bomar I bought thousands. Now only Bomar is still making xtals but crazy price $50.00 for 1 xtal an minimum of $100.00 order I tried again to order 2000 xtals 4 different freqs. and would cost. $10000.00. Just got this back the other day, they...

thanks for looking

Yes for the older 29s but I guess to reference the older 29s to the newer FM 29s. Will be interesting if the newer FM 29 can be modded for channels, time will tell

we are talking about the new FM 29s not the old

NZ8N any schematics for the board. And what is the part # for that metal bracket or where can they be bought? thanks.

Great thanks please let me know

So I have been doing some searching and reading. See picture posted on the 4 slot programmable oscillator. From what I read on the board it will be good for Am but not SSB or FM as you will not be able to vari/open the voicelock/clarifier to slide. Says it will not, but maybe can be used on ssb...

this is from kens Yaesu FT101ZD, FT107, FT707, FT901DM & FT902DM (HC-25/u): (*=$15): Ham Radio band-mixer crystals: ([0]# call Bomar for crystals that are not in our inventory) [0]#40.4875(26.0-26.5), [0]#40.9875(26.5-27.0), [0]#41.4875(27.0-27.5), [0]#41.9875(27.5-28.0)...

I dont know if its a trippler circuit crystal friend never told me.

I tried Kens and Barketts tried many places and no one has them.

I have a friend Im trying to help out. He need these xtals I think for a Yaseu radio 40.9875mhz 41.4875mhz Looked every where and nothing Is there anything else that could be used in place of the xtals?

So maybe a dual Expo signal injection 1 for transmit and 1 for receive just saying if possible would have to work so the transmit is injected when transmitting and the receive injected when just receiving controlled by a switch/relay. I'm looking at this as a split tx/rx system. I guess 1 way to...

Has anyone have an Idea if there might be a way to add extra channels to the new am/fm 29s ???

thanks for the info i will readup on the mods. thanks

So it looks like no extra channel mods for the newer 29's

Does it look like they are using a crystal oscillator programmable for the mixer frequency. I dont see that area on this new board

I was wondering if anyone here has fooled around with the programmable oscillators. I see a youtube video where someone used one for a cobra 29 for extra channels. Was wondering since crystals are very hard to find and cost too much if one could be programmed for say 11.4758mhz to be used to get...
