BTW, have you sold your R-274? Tom ?N5AMA

Well, you and I seem to differ on the value of that thread. I learned several things from folks here who have a wealth of knowledge. 73, Maynard W6PAP

So new thread started on the same dead horse. how many weeks will this one run? 52 HOPE IT BEGINS TO WORK

Hi Jim , and all; revising numbering makes it tough to compare things !!!! So the Halli C62 function remains despite our communication inability. I guess that it one reason I often take a snip

Maynard FYI S-40 [no suffix] https://bama.edebris.com/download/hallicra/s40techman/s40techman.djvu This seems to have no C62 and looks like “your” 40A at first glance ..SO maybe you have

The S-40B Photofact Folder that I copied calls it C7 but it is still a 2.2 pF cap just as is C62.? Sam's has a format that they follow so their component designations are not the same as

Maynard, yes wording is tough. “C62” had been started.. then it moved To me it showed that it was thought to be needed for a simple coil, but not for a transformer .. A version Then

And my S-40A schematic is from Sam's Photofacts (via the Web) and it doesn't have C62 as in your schematic nor does it use independent designation of each component, but labels them with numbers

Hi, Don, When I said that there is no C62 equivalent in the S-40A, I meant that there is no capacitor like C62 that is connected around the switching and resonant circuits so that it is completely

Maynard on the S-40A, C62 is in use on band 2 only but connects V1 and V2 like in the B version …I think. We need somebody to LRC a sample switch. Sent: Thursday, February 27, 2025 11:16

Note that the S-40A uses an entirely different arrangement of coils and capacitors and has no equivalent to C62 in the S-40B. So why is the S-40B equipped with C62? Maybe switch S1B in the S-85

Dwight, I like that counterweighted roof setup. I've never seen anything like that. It gives you great low angle viewing! The roof on my primary observatory is motorized so it tracks on rails but the

Emanuele Yes, I prefer to look at R26 and C29 as the plate load Impedance, so the V1 output voltage is developed thru it, and as you reiterated there is no V1-V2 obvious intended coupling in band

Nice looking setup.? I love New Mexico for the landscape.? You don't see this on the east coast. My step-son lives in Houston. We have driven there a couple of times and know it is a long trip. We

This topic raised in the "TRIMCAPs don't peak" thread. I think it's worth its own thread. Here it is. In the S-85 there is no obvious coupling between the RF amplifier tube (v1) and the MIX/OSC tube

Hi Dwight, I've attached a few pics of the Pie Town setup. Actually, it's two sites. One is a rolltop with a connected warm room. The other is a hill top site with a typical dome and an incredible

Hey Dwight, Thanks for the email. FB on your Rio Rancho observatory. As you might guess, I’m not up there every weekend for several reasons. It’s a 17 hour drive one way for me from Houston.

Rick W7IMM, If you would please contact me offline. 73/Randy WN9D

Hey Tom.? I had an observatory in Rio Rancho for a while.? I would love to see your setup.? My wife and I went to Pie Town once and they did not have any pies.? WTF!!! Let me know when you are
