I design these kinds of things. Much more compact than a heater core, and no fan, and much cooler. ok....end of shameless plug ! :) Seriously, these work for radios too, and you can totally get rid o
Martin, The problem with air is that to cool a space as small as a chip, and yet remove perhaps 80 watts of power from that confined space, requires substantial amounts of air. This is more than can
Ken, I certainly agree that we are not going to run cold water through 572B's. In the modern shack there are (at least) three places where there might be a fan, or a fan might be useful (RTTY), and t
Many tubes are cooled with finned heatsinks, which also double as shields. I'm sure many of you have seen this done. For that matter, many tubes have metal cases. Any idea if a 572B or similar tube h
Hi Gary, from Gary :) The condensation problem is real, but is solved commercially by insulating and sealing the cold side of the system. The hot side is remoted, to the outside of the case, using th
Hi Paul, I had a Pegasus for about a year. It was a nice radio, with decent performance and I liked it. I can recommend it for normal amateur use. If, on the other hand, you want a contest-class radi

I have not heard this yet, but will listen for it now. If you have more information about the signal, it would be appreciated. 73 de AA2IZ Gary but band this?
I've noticed that all the Corsairs I've come into contact with (3) are noisy compared to the Omni. I thought this was normal, due to higher IF gain. Is this right, or is it really a noisy FET ?? Is t
All - This grounding stuff really energizes people (no pun, groan). I have read many, many write-ups on this, and the best I have seen are those offered by Polyphaser and Alpha-Delta. Both of these r
I'm going to add one more comment to the discussion, and then I'm not going to post any more on it, due to the sensitive nature of the topic. I don't think that I can build ANYTHING reasonable that w
Yes, I mean all grounds... of course within a reasonable definition of the term. I probly won't connect my house to your house ! :) The barn ? Yes, of course. Gary companies, ground to common togethe
Rob, I'll be very anxious to know how your PTO lube job works out. I'd like a process that would allow me to avoid a disassembly and rebuild.... just flush out the old stuff and spray in the new woul
Of course, WD40 is not a water thin Solvent... it is a water displacer. When I referred to the solvent I had in mind products made specifically to be compatible with plastic, and to dissolve grease.
Axle Grease is the word ! :) There are folks out there that rub WD40 on their bodies for arthritis. Everybody who has seen the film My Big Fat Greek Wedding will know that Windex is the preferred cur
