Evidently not.. tube pins can go in pretty much any way, into these sockets at least. They shouldn't! Not with good quality sockets, anyway. But the UX4 base, where two pins are fatter than the other
Which is why accurate readings are done with a calibrated step attenuator - using the S-meter only as a relative indicator. But what is the resolution of the S meter? Most S meters have S9 at half sc
With the AGC off, and the RF gain backed down, there's plenty. I don't see it. If you have a meter that at S9 is reading half scale, and you want to reset a signal level to1 dB, you need to be be abl
When the RF gain is backed down and the AGC off, the S-meter reads on-scale. So what drives the S meter if there's no AGC? I haven't seen an rx yet that had a functional S meter with the AGC off. Ple
Is an EI core better than a C-core? In my opinion, Yes! The reason being is the heat. All very interesting, and useful info. But for some reason, nearly all the military stuff over here has, for year
I have observed that Hipersil core transformers have substantially more volts per turn than conventional core transformers. Does that apply to E and I core Hipersil, or C core? If you can run at high
I'm only speculating but is it possible that the difference is the orientation of the core? Don't know. Me too! 73 Peter G3RZP _______________________________________________ Amps mailing list Amps@c
The real test of non-linearity is the production of harmonic and intermodulation distortion. Exactly! The Luxembourg effect!!! (although that is actually cross modulation) 73 Peter G3RZP ____________
Will, Can you think of a reason why, at least over here, the military especially seemed for many years to go for C cores rather than the conventional E and I? C cored transformers were always more ex
I'm talking of ground stuff at 50/60Hz. Vibration might be a point, but I never had a problem meeting the DEF STAN L2 requirements, which a lot of fixed ground stuff had to meet, with conventional tr
I am not convinced that military procurmenet decisions are always that rational. That is very true. However, all the transformer manufacturers (and we had a lot of them) seemed to do a lot of C cored
But a bit more difficult to measure the other currents and voltages for which the reference et the cathode level. Has anyone an idea how to do that, on a simple way ? I agree with David Kirkby about
But how many reports of the "Luxembourg effect" over the decades have been due to cross-modulation in receivers? We skeptics need to know. The Luxembourg Effect was first noted in the 1930s when Radi
Does anyone on here still use turret terminal construction any? Yes, but getting turret terminals is pretty difficult these days, so I'm very sparing with the few I have left. I'd be interested in qu
Last thing removed Well, hopefully. Many years ago, as an apprentice, I worked in a high power tx lab. On one occasion, somebody had gone into the HV PSU cubicle (it was a cubicle - 22kV at 1.5Amps,
I'm not in favour these days of buying Agilent anyway - at work, we bought a $40k signal generator which failed inside 3 months. They took over a month to repair it, and wouldn't lend us anything in
I rather suspect that being in a position to tell the Agilent salesman to go away because you're going to specify Rohde and Schwarz or Anritsu rather than Agilent because of this might have some resu
But they regularly lubricate them. I no longer make slanderous comments about sleeve bearings. Ball bearings have lower friction for a given load bearing capability, but are noisier. For heavy loads
I certainly can vouch myself for the longevity of the "Oilite" bearings. The biggest problem is getting them in small quantities. Proops, in the UK, normally have trays full of various sizes of them
Back in the 'good ole days' of AM, I seem to remember that you never went above 1000pF, even at 160, because it bypassed the audio signal applied to the plate for modulation. I happen to have a 1200p
