REC86345 PLL
Models include:- Courier Blazer 40D/Renegade 40/Rogue 40/Nightrider 40DR/Ranger 40D, Fannon Fanfare 125F/182F/184F/185PLL/185DF/190F, Realistic TRC448
Uses simple 8 bit binary programming.
Easily modified by changing the loop mixing crystal.
Below is all of the Information I have on the TRC448.
Clarifier mod for TRC 448 (PLL REC 86345).
This radio has dual audio output transitors and high level AM modulation. Nice old radio. This info is second hand information from a good source, but I have never tried it:
Clarifier mod:
1. Remove d15
2. One side of the clarifier is on ground. Leave it.
3. Cut the wire hooked to the other side, leave enough length to connect to the positive (+) side of C333. LEAVE THE CENTER WIRE ALONE.
4. TC-4 adjusts AM Frequency and TC 5 Adjusts SSB frequency.
5. This should give you +/- 2-3 khz slide, usually enough for someone on a certified CB channel.
Adjustments:
*AMC VR5
*ALC VR204
*AM DEADKEY VR210
*SSB MIC GAIN VR4
Hope this help's some,
Lon
