I have a local e-waste disposal point near me, run by the county. I’ll have to check, but I’d bet that they can handle mercury without much fuss. — Jeff Dutky

Hi Greg, I have not seen any en-masse R/E/W refresh behavior for the ER1400 in the 2465. Most (or all) of the ER1400 is read on boot to verify the checksum but that probably doesn't count as a

I will check them out. I have a mini circuits DC block for the spectrum analyzer that is really nice. Was reasonable priced, As reasonably priced as a DC block well in to the Ghz can be. If that is

I had to check w/Wikipedia, but it says the open circuit voltage of a mercury cell is 1.35 V, and that they hold their voltage very level for most of their lifetime, so perhaps 1.25 is near end of

I second Jim's recommendation. In addition to better pricing, Mini-Circuits just has nicer folks. Pasternack once actually made one of my former admins weep. She had never been so mistreated by a

Hey, Zen, if you want to buy new 3.5 mm to SMA adaptors, check out Mini-Circuits.? A couple years ago I needed some for work and found the M-C ones about a third the price of rip-off Pasternack.?

Thanks, More is on the way. Zen

Zen, I like your videos and I think you do it well.

I don’t want to spam the list, But I will put it out there since it has been a while. I have video content up on you tube specializing in restoration repair and alignment of test equipment in

I've seen somebody on the eevblog forums had the same failure, he ended up soldering the wires directly to the board underneath.

Jim, Both versions of the manual state that the batteries should be replaced “when the voltage drops below 1.33 V, or after one year” but I will try adjusting the unit with the current batteries

Zen, can you please post the info here, so that everyone can benefit? Thank you very much.

Dave I will shoot you some information off list. Zen

Mark, The spec on the GI ER1400 data sheet does indicate that the data is retained for a minimum of 10 years but does not indicate if that is when the device is never accessed/written to over that

I've recently acquired a 284 that seems to need some TLC. Before I start snooping around in it, I'm wondering if there are any "usual suspects" that I should consider. Besides all the electrolytic

Picked up a Tektronix 2232 scope at a Club auction recently. It has a dot with the "beam finder"but no trace. You can move the dot vertically and horizontally with the position knobs. Opening it up I

Hi John, Michael Lynch just taught me how to post a photo. Visit the below included link. The instructions are easy to follow. Regards, Ken

Hello Can a picture accompany a message or does it require it being sent to the Photos? How do I do that? Thanks

Looks like it's missing a second page. BTW, I have a spare Model134 Amplifier, if anyone wants to buy one.

!.25 V sounds just about right for a mercury cell, but low for an alkaline.
