Don't mess with the PIEL software.? The gold standard is the GM3SEK? PI / PI-L spreadsheet.? ?It's better since it factors in everything, like stray C....and also the all important stray L? Any

How do I calibrate the power meter in the ALS-600? I guess thru a hole in the label below the RF Out connector on the back. Joe? N9VX

Everything is in bound. I found the relays and made an offer on the trimmers and the seller accepted. Going to have 125 bucks or so into this. Will probably need some mica caps also. I have some, Fred

I could tell I was beating a dead horse when all the HFers ignored my earlier comments about plate bypass capacitors made of two metal plates with an insulating sheet between, and then when they kept

Steve, K0XP said "Try a 3/4 wavelength stripline. Get the design info from W6GGV's articles published in the Nov. '80, and Jan. through April '81 issues of Ham Radio." Thats right, Steve! a stripline

If I start from the assumption regarding the input impedance 35 ohms in parallel with 92 pF, this is equivalent to 3.37-j11 in series form. If we calculate the 'L' adapter, it gives this Why would you

Jim, is there public domain software program that helps with Pi network design? aka, I'm looking at 8877 50Mhz project in 2024 73 Robert W5AJ

What does the piece of Heliax do?

Jim, are you building this?

YC-156 is good up to 150 mhz.? ? It will be used on 144 mhz. Yes, the 8877 has a 38.5 pf? between cathode and grid....and is good up to 250 mhz. Question is.... how the hell do u make a tuned input

Yes, that's 2 1/2 times the value for a 8877 that works good up to 222. Will this tube go that high?

Ok, how does one go about building a tuned input for a 144 mhz amp, using a YC-156 tube ? The input C on the YC-156 is huge,? 92.5 pf? ?( grid to cathode). This is for a cathode driven? ?YC-156 (
