Doug,Which Chelegance antenna do you use? BobKF6ABC

Great Eric, my Chelegance is 1.2 or better swr at all of those bands, of course I have to change? antenna settings.? ?But no loss through a tuner.? The important thing is to operate.? ?Chasing

I think I will be at Baylands with an FT-817 and a raised radial vertical made from an element from a triband yagi.

I plan to be at the Baylands, starting with lunch. Hope to see many of you. Hiroki AH6CY

Hi . Doug, Glad to hear you are having fun chasing POTA!? I think POTA is a great boon for younger hams learning CW.? I chase POTA on occasion, and did one activation so far.? I had hoped to

I have been? having a great time working Pota chasing Activators.? ?I have 32 states worked and 26 confirmed on Pota since June 5th.? All cw and 95% on 20m.? Using inverted L up 27ft and

I was just going to post that. Thanks. *MEMBER BULLETIN* July 1, 2024 Dear ARRL member, *Effective 12:00pm ET / 16:00 UTC we will be returning Logbook of The World? (LoTW?) to service*. As work

Thanks.? That explanation is what some of us were guessing.

Thank you Phil.? ?It was perfectly readable and reaffirms my belief in adding the diode.? ?Thanks, Doug

Doug- Attached is a rather lousy scan of the page but should be sufficient. Let me know if you have any questions. regards and 73 Phil, KD6RM

Could you please post a picture of your quoted material?? I would love to read it.? Thank you.? ?Doug

Eric and all, This is the latest re Covid quarantine. Hiroki AH6CY The nation is “in a different place” with the COVID pandemic than it was four years ago, said Dr. Mandy Cohen, who directs the

Hiroki- The zener? protection diode is a common design practice and is favored by Wes Hayward, W7ZOI. In his ARRL publication "Experimental Methods..." he explains the design on 1.19, fig. #1.35.

I just found out I was exposed to covid either Friday or Saturday.? What is the current thinking on quarantine?? Needless to say, I won't make Baylands.? Again.? However, the batteries in my KX2

Doug and All, I took a look at Steve's ATS-4 and Doug is correct there is a 47V zener diode across the FETS in the PA, so this has been used on simple CW amp. designs for some time. I still think that

I also have a Q-Match manual tuner that has a tune mode with a resistive bridge that keeps the SWR below 2:1 under all load conditions. I agree, this type of tuner will protect these simple FET QRP

I will be out of town this Friday, so see you next week.. Dave W6VYC

I would like to do an infrared survey of the board and zener running into an infinite mismatch. If the power is going into the 1 Watt zener, it might be overheating. If some power is being dissipated
