What has me curious is..... how can the PLL be "in lock" if the VCO is running at 70 MHz??? My brain pulls me back to that!

That is an excellent thought. I hadn't considered any kind of unwanted oscillation but you are absolutely correct!!!! Much appreciate the additional input.

As far as having a carrier on SSB.... IC2 is your balanced modulator. I would do some scoping around there. It should be getting in RF and AUDIO and putting out double sideband carrier suppressed signal.... so the carrier should be getting nulled out right there in IC2. If it isn't...

Receive only on HOT signals? On the surface it would seem like the RF/IF section is working... albeit at low gain. Some things you might check (may sound odd)... AGC and Noise Blanker. They both serve to control gain in the RF/IF strip. AGC does it normally to create an even level for...

Good luck nursing your way back to normal!!!

Thank you so kindly.... I am pretty sure I have it though! Through the years I have collected more info on the SBE Console V "than the law allows"!!!! There actually is a SAMS that covers almost all of it. The Console V (also referred to as CB-40!) had a mobile version called the...

Now THAT is what I SHOULD BE DOING!!!!! :)

Hawkeye351, please don't interpret this as a "sermon"! Actually intended to be "encouragement"!!!!! I truly hope that we have not seen the last posting from you. In every forum that I have become part of... there are those willing to jump in and help, there are those who want to criticize...

I did finish it quite some time back. At the time work was keeping me busy and I just never got back to it. But retirement last year came around so FINALLY I got it out to take a look at it. While aligning it.... a DVM probe slipped.... and the little transistor regulator on the AC power...

JUST to describe the weird space I am in!!!! I went to DeVry - Dallas in 1975 in the Degree program. Right after I got my ASEET I was hired on at the NASA JSC to work in the Shuttle Mission Simulator facility where the crews trained. I took off on a path at work that led me to move into...

Just looking at the SAMS CB Photofacts and I see that the Cobra 21 and 25 are in the same volume. So if the same SAMS copy covers both radios.... how do you know what the differences are? Surely a 21 is not identical to a 25 or everybody would have saved money and gotten a 21. I did see...

Thats a good idea.... gluing extra metal. I like that better.

Shipping hit me for about $7. The whole deal was about $23 and a bit of change....

Well... I came in to answer the question in the Subject line..... I have two... A B&K Precision 2040 CB Signal Generator for basic CB/11m band work and if that doesn't do it..... A Boonton 102F 500 MHz AM/FM RF Generator that covers anything else up to 500 Mhz Then I saw.... "a budget" On...

I imagine most may already have a way that works for them but I am just thinking of newer folks trying to build up some test equipment on a budget. This might help some on their benches with setting driver/final bias. Surely you can do it with a DMM but some might consider this to be...

Dan, just a report of some sad news. My ability to help out.... just got "knee capped"!!!!!!!! WHAT I HAD WORKING was..... IF you live IN Texas... you can pay about $24 a year for a remote library membership with the Austin Public Library that gets you in "online". THAT part still works...

It is still... in my humble opinion... goofy to have multiple part types with the same number. Do bear in mind..... I said I was getting WAY too old... ;)

I'm obviously WAY too old. How are you supposed to know "what part is what" when multiple SMD parts have the same marking??? I like old radios! ;)

Ahhhhhh!!!!! Did you join all of the same groups on there??? (BTW it was Steve Butler.... looking for SAMS for a Realistic TRC-431.... which I promptly sent him!!!! He was just concerned about you!) [edited to add] Here is the message he sent me... he did not say what group he tried to...

Dan, are you alive and kicking out there? I got a message from a friend on one of the FB forums who had sent you a request and has not heard from you. I'm thinking..... Christmas/New Year holidays.....you are taking some time way. But.... I thought I would let you know that "the world...
