2)Find IC 6 & 7 by the PLL chip. Here's how to do a 10 Kc UP jump only:
chassis, which provides better grounding for the audio generator and can Uniden PRO 510XL: Type: Mobile: Version: CB-Radio: Frequency Range: 26.965 - 27.405 Mhz: Channels: 40: Power Output: AM: 4W: Multi-norm: ANL (Automatic Noise Limiter) CTCSS: 3. This is a modification to the Uniden Pro510XL CB radio which . Notice This model operates on any of the 40 AM frequencies authorized by the FCC, and its S/RF meter and red-lit LED indicators help you monitor activity at a glance. RESOLDER this ORANGE WIRE
1. mod kit by soldering one wire to each of the 220uF capacitors leads. (Mike circuit changes:)
Step 8: Solder the negative leg of the capacitor to the ground foil at the bottom side of the radio. modulation method. 2)On the back of the clarifier knob follow the green wire to the PC board.
The normal tweak says to replace the 2.7ohm resistor in front of the final, with a .47ohm. 6. 1. VR13=AM High Power, VR14=AMC for AM Modulation VR16=AM Low Power VR20=2nd
here are those three mods in brief: Are you confused about how to perform these mods on your Uniden Pro 510 XL?
Find D75 (located near POINT 53 and VR15) and lift one end. Pictures, Manual and Specifications of the Uniden PRO 510XL AM CB-Radio / Plaatje, Handleiding en Specificaties van de Uniden PRO 510XL AM CB-Radio CB & Export Radios. Replace R43 (10 Ohm) with a 2.7 Ohm. It is lying flat on the board. (NOTE: This plug may already be attached when you get your
i have a meter. 7. Step 31: Solder the positive leg of this capacitor with the short you made in step 29. unsoldered. MODULATOR AND VARIABLE POWER
3. Replace R126 (10k) with a 2.2k. CHANNELS:
Use a SPDT switch and wire as follows:
