In this case clipping it might be the simple way to make it sound louder and swing a tad more. need of it and it takes up valuable space. Replace R78 (27k) with a 56k. even after adjusting. Whenever I say "from the left/right/rear edge", I mean from 1. Use a SPDT switch and wire as follows:
Note that this will not work on all channels. You now have 8 bands, Channels 25.165-28.755. (8 volts)
Isolate pin 9 on the pll for a 5kc drop. Internittent audio/modulation: Bad solder joints on
OVERMOD: Check D11. Remove R174 and solder a jumper wire in its place. With the CB in transmit and the generator applying a signal to the 2SC2166 and make sure 12V is getting to it -- if not, check the jumper that you Double check all work for shorts. by hamguy2 Thursday 30th Oct 2008, 6:14, Post Follow the YELLOW
2= 27.455 7= 27.515 12= 27.585
5. i have several new old stock units available. Replace R124 (10k) with a 4.7k
It brought the modulation up without overdriving it. Your email address will not be published. Solder a jumper from where you removed R174
2. One side of switch goes to the cut side of pin #16. This will allow you to jump 10Kc up or down. Re-tune coils L37 and L38 for maximum forward swing
hacking your radio with a lot of switches is to install the EXPO
Step 9: Then locate the L2 transformer. by fantacmet Monday 28th Jul 2008, 18:59, Post 2. SSB/CW S METER VR2

Then you must have about 1Kc slide up and 5Kc

1.
Step 33: Now flip the radio set so that the front of the radio is facing you. also is there a way to add talkback without a pa system. Reconnect the plug to the board. 2. It features an instant channel 9 function where you can quickly set the radio to the emergency/channel 9. Cut trace to pin #16 on the PLL. Re-tune L9,L6,L5,L4 for maximum forward power. by absorbentgnome Wednesday 30th Jul 2008, 8:04, Post 1. 4. 3. 2. Well the finals are so cheap, and I'd rather have a little gain then the factory 3 watts.
I just did this mod in my shop here today. 29 LTD:
(DO NOT change the 15 Ohm resistor!!) 2. This only disables AMC not ALC. Remove D51 and put in a jumper. Resolder this WHITE WIRE
(Transmit circuit changes:)
When you apply the 8 volts, this pulls pin #16 high causing
Well I swapped the 2166 for the 1969, and fried the D7 Diode pretty bad, so I put the 2166 back in, replaced the D7 and Radio is working again, perfectly. If you have a meter and you can tell what the power is ? Place the two wires from the RF gain control in your mod kit by soldering one wire to each of the 220uF capacitors leads. No cut to the PLL is necessary. ALC VR12
1. Take it up and back it off a bit from there. 1. factory original setting. CARRIER BAL: VR5
transformer. Relay buzzes on SSB, no am transmit, lights go dim, or
forward AM power. Three modifications are commonly performed by radio modders on the Uniden Pro 510 XL. Re-tune L9,L6,L5,L4 for maximum forward power. 8.VR10Final Bias
The Uniden Pro510XL can be used to remove noise and improve communication reliability and clarity with an integrated ANL and squelch control. These caps
Here you go: 1- 100uF 35v electrolytic capacitor, 1- transistor

In some country performing these may be illegal. 9. CHANNEL TWEAKS:
CB World carries an in-dash mounting kit for this CB radio. 10 Meter Mod, 1)Find IC7 ny the PLL chip. 5) Reconnect the plug to the board.
Replace with a 16v or 25v. About the Product. This wire is no longer used. the following:
ASSEMBLY:
2. im assuming you have the older versionyou can replace the finalkind of like putting perfume on a pig though.not worth the cost of the final for small gains.
