Hi Dave, I goofed and deleted the link to the RAD Lab books. Could you please send it to me again. Thank you. 73, Bill, WA2DVU Cape May

Hey Roy! Nice bumping into you on this forum! I still have that RT-1 xmtr... Pete

Right! And those pulse circuits were fundamental to early computers in the 60's, such as the DEC PDP-8, which was made of discrete transistors, pulse transformers, etc. Pete

Yes, Robert, that's the info that I've been using. It's pretty slick the way they did the rotational timing by virtue of the wafer contact tab shapes - that's why I reused the original switch. My coil

The Waveforms volume is one of my favorites, in particular the "time selection" chapter. Early sampling. :-) -Dave -- Dave McGuire, AK4HZ New Kensington, PA

To repair my 5343A, which to me is a very complex test equipment, I got a 5342A from a friend to swap PCBs for localizing the faulty one. The problem was finally tracked down to the A12 IF Detector.

I have a very nice HP54601A with: (2) HP10071A probes and (2) Probe Master PM2504RA probes (1) HP5654A self-paced training kit for the HP54600 series? (1) HP54600 series Users and Service guide (1)

Just to get more insight in the working of the bolometer heads, are PTC or NTC thermistors used in the heads? I like to build something wich would work, but some little lamps did not do the job, I

Agreed. There is far too much off topic stuff here. I will lock this thread Dave (group owner)

You can lead a horse to wisdom, but you can't make him think... Wisdom, Horse.... Horse, Wisdom.... er.. HORSE, WISDOM! (Neigh....) oh, wait, I'm talking to the wrong end of the

Prior to WW II 5% of the population went to college. Medicine, dentistry and engineering were single degree professions. Liberal arts, which used to mean science, math, history and literature, was

Very impressive work. Lucky you to have an FSIQ also. Regards, Mark

Amazing work there!

Hello, let me tell on a point of certainity that Iran has NO F16s in flight capable config. One of my clients would have given a lot of money for shortterm access to such a vehicle, and would have

It is a lot more than just F16's, and F14's. Iran has lots of F4's, F5's, F14's, several hundred, I think... all are being denied maintenance. So, they have bought MiGs of various flavors from

Update: I have made a successful prototype run of a 1GC1-4210 drop-in replacement PCB for the following instruments: 250 kHz – 1 GHz: E4423B, E4434B 250 kHz – 2 GHz: E4424B, E4435B 3GHz and 4GHz

If the standard HP packaging was used, then any other same-sized instrument of the era should have interchangeable cabinet parts. Possible exceptions may be color-matching, or if any unusual features

Perhaps I should have said postgraduate degrees.? Corporate engineering jobs seem to require it, and many states for getting a PE accreditation. Yes.

Hello, What made the issue really quixotic was something else. The Austrian university in question had the books, in course strength, in the library. But, oddly, they still did not find the time to

Hello, a small correction: the IRiAF received F14 not F16s. I know it is OT, but as someone who still dabbles in the field, I can not leave it standing. --- With best regards Tam HANNA (emailing on a
