Kid_vicious,
The TRC-444 should have the LC7185 in it.
Hope this helps,
Lon

This i found on a web site ..
"This chip uses ROM programming with direct VCO division.It only has one programming bit to step UP or DOWN,getting rid of the BCD channel selector switch.No chance of modification." |

darn that rad shak!
they never did want me to have fun with my radios.
flashgordon, this is one of those radios that you put a good power mic like the DM-452 or the D104 M6B
on and stick it in the wife's car.
it will always work, and with the power mic, it wont sound half bad. you could sell it, or if you didnt pay too much for it; you could use it for a learning radio and start cutting out parts and seeing what smokes! it's so fun! J/K
good rad shak radios for mods are the TRC-457,458, and 490.
look for them on *bay.
have fun,
matt |
