Thank you sir! Much appreciated!

@danmcclain - *********** NEVER MIND!!!!!! **************** The friend had it available and sent it to me. So I really DON'T need this... I just left it here to avoid deleting it. ************************************************** Dan, I hate to pester you so soon... but I'd like to see if...

I saw those numbers you mentioned in 399's paper... but don't know where you would go to get the 1208a version......

Thank you once again!!!!!!! I appreciate your taking the time.

I am really not sure Dan....... I have never seen anything like this..... production changes listed in a SAMS..... are they actually ON the pages like he says????? If so...... are they something you can copy??????/ Thanks!!!!!!!!!

Dan, I wonder if I could call on you for a slightly DIFFERENT kind of favor???? I am reading 399's great paper on various uPD858 radios and how to care for them. In one section... he mentions the biasing of the finals in ORIGINAL President and Cobra radios as using a 70 mA bias circuit and...

I appreciate every bit of it and thanks for taking the time to send it!!!

Thank you for the reminder.... as I long ago pulled down his PDF paper on the uPD858 platform. I will certainly go find it.

I have what I am calling a labor of love to do. A few years back a friend of my son Tim (Skip... who owned Outlaws Toy Radio CB Shop) died of a heart attack in his mobile repair van while working on a radio..... parked at home. A short while later... his wife let Tim come over and take...

Sometimes, a good box of crayons and 4 fingers of whiskey helps my troubleshooting endeavors!!!!!!!!

I am hoping that the attached sectional may be of some help. In that last post I was speaking of "switching the 7.8Mhz that winds up going to the XMIT MIXER". This drawing is an attempt to give you an idea of what I have stuck in my head. The BLUE colored path is the Balanced Modulator...

I am actually doing my day job at the moment... but I just had a thought that compelled me to come back here and "blather" some more. None of this may make any sense.... I may be way out of my league here......... But.... You say that your transmit is off by about 2.8K. It just hit me that...

I'm dragging up late on this one.... Have you done any "nosing around" in the area of FET7? That is the XMIT Mixer. Just to verify that the inputs are good, that the voltages present indicate a proper bias condition, AND if the output of that mixer is on frequency?? Just an idea....

"You can lead a horse to water but you can't make him think".

I have to wonder what they "MAY BE" doing wrong with them??? Those batteries are used "all over the place" in ham for backup systems AND for portable operations. In all the discussions, videos and talks that I have seen on portable ops with these batteries... I have not heard of one in THAT...

Frankly, I think I have gotten over any concerns that I had from this guy's input. I'm feeling all better now. :D

Today's hamfest was good in that I got to fill a hole in my bench!!! I think this one looked particularly clean and the guy wanted $120. I have seen them a LOT uglier... for a LOT more.... so I just paid him and took it home. No slug... so I still have to find a good 'H' slug somewhere...

I was going to say........ Seems like 4 or 5 years ago ....average 23 channels were $10-$15 US ... and 40 channels were $20 to $25 US. It's CRAZY now. What you say makes sense....

Good to know.... about the opinion on the bipolar version........ As for the displays... it will all come out in the wash..... For one... I can always scope the LED driver lines from the chip to the resistor and on to the display segment and see if something THERE indicates a difference in...

Those LEDs are one of the primary things I am researching.... It appears that it is a 3 digit unit (2 of them) but... the question is..... are they that wildly different from similar displays that you might find at Mouser or elsewhere??? Are they common cathode or common anode? And what...
