To? GROUP? members, Many are mailing me to reserve Red Devid resistors for them.? Back in Minnesota there are enough Red Devil resistors to go aound.? The issue I am faced with is that I was

Hi Most modules do not have a battery but stand to be corrected As I have a 70900 open on the bench I will do some pictures relating to changing its battery Just remembered have just bought another

The purpose of this topic is to organize and summarize the replacement of batteries in the HP70000 modules I have several modules and no experience. It seems the manuals gloss over this important

Gary and GROUP, Yes, I can supply you with one.? ?I can help most of you that have mailed me with requests.? I may not answer you quickly as I am very busy these days packing and sorting but I will

Hi Dave and all There is a 70000 Group We could put any service information we have on that site Regarding batteries for the 70900 it seams I will require a few Regards Paul _____ Sent: 18 April 2020

Hi Dave just came a cross their listing on this group and they had some manuals that you don't have that I would have liked Dave can we have a chat about 70K manuals regarding my last Email to you

Thanks Paul for those cautions. I had hoped someone had done an article or series of notes on the battery changing. Not to hijack this thread I will start a new one. Thanks Dave VE7HR

Hi all Warning the 70900 a low / changing the battery will loose its program and a lot are not available I will be soldering another battery in parallel on flying leads before removing the original

DON'T bend the tabs, no matter how desperate you get. I once had an HRO receiver where a previous owner had bent the tabs to get perfect tracking at the 50 kHz calibration marker frequencies.

I guess I need to get a bunch then as I have 4 of the 5 and multiple instances of some. I am thinking the 70206 probably has one also I see Digi-Key has them but can’t ship to Canada. :-( Thanks

Off the top of my head, the following modules have batteries: 70004A Display 70100A Power Meter 70205A Display 70700A Digitizer (WARNING - disconnecting the battery causes program loss) 70900A/B LO I

Now that is ugly :-( A question. I am guessing that is the battery that is in the 70000 modules. Does some one have a quick reference to where they are located and which modules have them? I am

Wow. THAT is what I call a mess! I've never seen an Li cell go like that before either. I wonder if someone put something else in there. -Dave -- Dave McGuire, AK4HZ New Kensington, PA

Went to pull a 70205A system display module off the shelf to install in a 70001A, and found the following surprise: Evidently the module has (had) a TL-5104 3.6 Volt Lithium battery behind that door,

I thought you did have the datasheet for the HexaWave HWF1681RA MESFET - I found it right away. With that, you can tell which pin is the gate, and also approximately the desired operating conditions.
