IF and I have to emphasize the IF these transistors were rugged enough for prime time and I'm quite willing to take your word on the power you are getting out, the manufacturers would be jumping on t
They are sealed systems just like the heat pipes on CPU coolers. Otherwise you'd just end up with the coolant vaporizing and then condensing in the vacuum pump oil. 73 Roger (K8RI) www.rogerhalstead.
If you overheat copper you are getting it way too hot. and probably damaging the dielectric as well. Overheated copper becomes soft. Today's popular cables uses braid plus foil and that braid is extr
There's usually more money in high volume, lower price and these new devices look like they lend themselves well to less protection, lower price, fast build . Of course that'd mean more legal limit a
My solder techniques are much more sophisticated. I use a box cutter. 73 Roger (K8RI) _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.com
That's the advantage of that old tried and true coax. With many of the new LMR and CNT cables you have to carefully score the jacket and then break it. I think you could ruin the braid with a rough f
See how much more advanced us rich farmers were. My folks installed indoor plumbing just before I came along. Unfortunately that last sentence is not a joke. <:-)) 73 Roger (K8RI) ___________________
Viking had a legal limit transmitter (Invader 2000?) while Hallicrafters had a legal limit transceiver, the SR2000. I have a top of the line transceiver the Yaesu FTDX5000MP and what was a leading tr
If I've followed correctly so far: We're talking N connector center pins. I trim every thing to length and then solder and/or crimp the pin to the the center conductor. Then insert the cable until th
And there are people out there that didn't expect this? They are running into low impedance loads which means high currents and high losses. I believe the Palstar manual even mentions this. Also the
If I have followed this correctly: As this is a single, PP amp fed with two independent exciters how do you maintain proper phasing which is critical? Even if the exciters are synchronized a tiny dif
I think we are running into semantics, but the way I see it(depending on how active feedback is defined) if the math is done for either the flywheel or the caps they do see what I would call an activ
It just needs to be a very high resistance at any operating frequency, bleed static to ground, and hopefully trip the PS out if the plate blocking cap goes. The general consensus is that the old 2.5
Hey! If Obama can still blame Bush, we can still blame you!<:-)) What were we talking about? 73 Roger (K8RI) _______________________________________________ Amps mailing list Amps@contesting.com http

Who do you think winds those auctions? Does and L4B actually put our 1500 watts? Now if it were a heatkit, unassembeled, in the original box, it would be a true collectors piece. The Viking Ranger I
I remember when the adds first came out for the Hunter Bandit. IIRC that one came assembled, but from the kits to the final Bandit, I kept saying I want one of those. I don't remember if that was dur
3CX300A7s (8874's) are still listed as being made by Eimac and RF parts lists them but they are very expensive. 73 Roger (K8RI) _______________________________________________ Amps mailing list Amps@
Most came with non hazardous oil although many hams did put PCB oil in them. Did it smell like oil or mineral oil? If so it was not PCBs. Go to an industrial paint supply or even your Ace Hardware st
Not exactly. Only half sand...IE, sand is quartz SiO2, The solid state devices are generally made of either Silicon or Germanium although there is a layer of oxide in there. Solid state devices do ag
