A bunch of DXers and Contesters I had work week regular lunch meet. We had a saying: If your tube doesn’t have handles you aren’t squat. (Polite version.) QRO comes in more than one form. The most

A dual motor Tesla does 234km/h (145mph). That is illegal but we are all encouraged to buy one. We take on a build of a big amp to prove that we can do it. That's why I've built a YC156 amp and helped

I suggest that you get a horse to replace your car that might go over the speed limit. Sent: Monday, October 02, 2023 11:45 PM To: [email protected] Subject: Re: [ham-amplifiers] 12 kw 160-12m

You know, I figured I'd get something like this ( hits self in head ).? Sheesz Andy? K9ATX

Any trapless yagi? or wire ant will handle it easily.? 12.8 kw is 16 amps into 50 ohms.? RMS voltage is? 16 x 50 =? ?800 volts rms? = 1131 volts peak. The CM choke is the trick part.?

Something efficient and has very low losses. Joe WB9SBD

AWG 36 with a green PTFE coating and a full 241 feet long .

Wondering what kind of antenna is used that will handle this much power? A

I designed this amp (back in 2007) for a buddy, who is now SK. Current owner is in MT. It uses a custom 253 lb Dahl plate xfmr and 24 x 3900uf lytics. Vac relays used for the input + cut off bias.

60/50 = 1.2 SWR of 1.2:1? is good enough. Typ with DL resistors..... once u cook em a few times, they will drift a few ohms up in value.

My Bird 5Kw reads 50r + - 2 ohms through 900mhz , but I wouldn't hesitate to feed my 30S-1 into a 60 ohm load. Don W4DNR

If you use them (or it) for a dummy load, they (or it) will require a large heat sink. 73?? Bill K3HZP

Gents, Looking at resistive DL's for QRO is an interesting pursuit, and the recommendation about employing a VNA makes it a good return on investment when selecting the "bits." One of my DL's is a
