Gang, When replying to a post, please try to avoid automatically quoting (including) a lot, or all of the prior message.? ?Often you can just leave the old stuff out completely. With the AA battery

Re: 8924c memory loss
I'll look into the battery changing.? I hate things with batteries in them for long term usage.? About as bad as some things that use that Dallas clock chip that has to be changed about every 10 or

Put it on your to-do list to CHANGE those AA batteries pronto!? ?Whether that's your immediate problem or not.? ?On all three sets, too. When you do I pray you'll find not a spot of evil battery

Hank, I did not know about changing batteries.? I have never changed any batteries in the sets. I actually have 3 of the sets.? The oldest I bought over 10 years ago.? It was only opened by me 2
Re: 8924c memory loss
Ralph, I'm going to take a shot at this even though you have way more operating experience than I have. Have you ever changed the two AA cells since you've owned the instrument?? They should be

8924c memory loss
What would cause a 8924c to loose the memory. That is I had it setup to come up in a FM service type mode by the command POWERON. Now it reverts back to the cell phone test screen. It has worked well

Re: 8924c 60/100 watt upgrade kit
Yes - that was the kit I had used where you sent back the card, etc.? ?Ok well again I was just curious.? And yes, a screw gun would help big time with this work. Thanks so much for all of the info

Re: 8924c 60/100 watt upgrade kit
Yes - I saw those pads on eBay and that was what I did with the one 8924c that was upgraded.? You got a pad where you removed the one that was there and soldered in the new one which had the higher

Re: 8924c 60/100 watt upgrade kit
You really need an almost 20 db pad as the 3 watt version already has a 4 db pad that is removed.? I think the heat sink is the same for the 60 watt and the 3 watt versions, so all you need is the
Re: 8924c 60/100 watt upgrade kit
Thanks Ralph - that is an option and there were other posts that mention where to go to create the offset in the power.? You would need a 16 dB attenuator ideally to put the 100 watts down to 3 watts
Re: 8924c 60/100 watt upgrade kit
