I need a manual for a TRONIC PLL 2023 radio - Radio Communications

Question edited for clarity.

Are you sure that model number is correct?

Sounds like a problem with the VCO / PLL Circuit since nothing happens in RX or TX. Check to make sure you have the correct supply voltages to start with and also check to see if you have 10.240Mhz. Use the service manual and go through the PLL/VCO alignment section. If anything is missing then you at least know where to look.

No.

Nice choice of radio i have the Grant LX Uniden which is roughly the older version.
This site may be of interest also if you choose the channel mod make sure you have the right PLL. http://www.radioaficion.com/HamNews/mods/mods-cb/2428-uniden-grant-xl-mods-pll-agc-power-clarifier.html

If the PLL is dead, it's almost not worth saving. Even if you get a replacement PLL and change it, the radio will not work right without an alignment. To align the radio you will need the factory alignment guide, watt meter, volt meter and an oscilloscope and a basic knowledge of electronics.

would love to add mid band through pll how do i do this

Depending on what you mean by "off frequency". The 29LTD, like all other 40-ch radios is PLL controlled, referenced to a 10.240 Mhz crystal. The channels are all mathematically synthesized by a higher frequency VCO and the PLL controller chip. If the PLL detects the frequency is not "locked on" it shuts down transmission. If the frequencies are there, but "out of band" then I suspect that there has been modifications done to the radio to make it so. If you want the radio back to stock, undo the mods. If the radio is out of band, and no mods present, then there is a problem with the PLL. Sometimes that may stem from someone getting into the radio and "tightening all the screws". (the shops just LOVE those!)
If the channels are in band but seem a little off, there is some adjustment in the form of a small trimmer capacitor near the crystal. But to adjust it properly, you should employ a frequency counter.
