Ten tec corsair ii unlock?

I've never dealt with a pto tuned radio. It has a pretty nice rx. Definitely can't used 29.5 mhz since it has no fm capabilities.
So that would be fine with me.
Very quiet rx but does drift per spec at 200hz per hour.
that transceiver is not easy to modify the frequencies, and honestly isnt worth it. alot of work, time and trouble if it can be done at all, finding components etc. ten tec is the one company that likes to keep their mars/cap mods very tight lipped unless you prove to them you have your ticket.

According to them this radio was never mars cap capable. The company was bought by a douchebag who also bought alpha. He was talking stupid to people on a forum about the company's status. He's just a rich wing nutt with a attitude problem. So now days it's pretty much done. There will be no more ten tec as we once knew. Even if he makes more stuff it won't be the same . They moved both company's to Dayton Ohio.

Each band selects a crystal. The one that covers 29.0-29.5 is 14.99 MHz, schematic calls it Y9.
To cover 2 MHz lower should call for a 12.99 MHz crystal. The radio won't care which 10-meter segment you pull out. The crystal will work in the 29.5 socket in place of Y10.
Closest one on Ken's ELectronics crystal page is 12.9875. And no guarantee how far off that frequency it would show in this radio. All crystals are not created equal.
If this crystal is too far away from the intended frequency you won't be able to calibrate the radio's frequency display for that band.

I'll look through my box of xtals. Is Ken's still really selling xtals? There are oscillator modules you can buy in lieu of a crystal like tcxo modules sort of
Ahh, twelve point zero is not the same as twelve point nine nine.
That crystal would be almost 1 MHz lower than you need to cover 27 MHz. A 12 point zero MHz crystal will get you a band that starts at 25.990 MHz to 26.490.
A 13 MHz crystal would only put the tuning dial 10 kHz off from its markings, covering 27.010 to 27.510. A 12 MHz crystal is 1.1 MHz too low to get 27MHz.
The 12.990 you need may not be readily available, but 12.0 is not terribly close. Ken had one listed a lot closer.

It works to to 26.6 . I was listening to stations on 26.555lsb in south America today. It loses lock long before it gets very low in the band. It's worth using it in the 29mhz spot and then I can order a 12.8mhz for the 29.5 spot . That's what's available unless I want to do something creative. It's not worth it. But it's cool to see it will work if I want to. I've got about 16 hf radios not counting cb radios. So anyway just having fun here playing around.
