Ed you must be talking about those XE stations tuning up on SSB on the low end of 40m. They groan "hoooooo-la" while they dip the plate control ! SOP Best regards - Bry Carling
The only thing I ever "dip" is a little chew. 73 Bob, K4TAX -- Original Message -- From: "Brian Carling" <bcarling@cfl.rr.com> To: "Ed Purvis" <wa4njy@yahoo.com>; "Discussion of Ten-Tec Equipment" <t
"Dip" was pre-watt meter days. No need to dip anymore. Just tune for maximum smoke! Precisely, running full drive power, you first tune the PLATE for max smoke, then repeat the sequence of slowly adv

Rick, I do a 25/30 watt drive tune up for resonance as well. Helps my very old AL-80a not grown so much. :-) 73 - Eric W9WLW <snip> -- Sent from my Android device with K-9 Mail. Please excuse my brev

I'd say so... but that's not the case for my AL-80a since it only has one 3-500z in it. The drive requirement varies some for me... and I was just sharing a ballpark figure. I watch the meters very c
In that case you use 10w. (Or do I need to make a chart for each amp on the market?) ;-) 73 - Rick, DJ0IP (Nr. Frankfurt am Main) When 33W input takes you to 1500W out, 30W initial is very aggressive
Yes in a Class C amplifier one typically will adjust the plate circuit tuning for a dip in plate current. Then one should adjust coupling for rated plate current or rated output. Then adjust the plat
I've never been told of this trick for tuning for maximum efficiency of a class C amplifier. Is there someplace I can go to learn a bit more about it? I ask because I have a WRL Globe Champion AM tra
I comes from many years of tuning AM broadcast transmitters. The "right side of resonance" refers to adjusting the tank circuit tuning capacitor to a slightly lesser value of C which is normally turn
Ah! I've noticed this but never understood it. At least with the Globe Champ 350, the power output can increase quite a bit off resonance to the right, but the plate current also quickly gets way out
Bob, I'm glad you added this "clarifier". "The right side of resonance" is only true when minimum capacitance is clockwise and max is CCW. Normally that is the case but it might be a bit risky to ass
In a word "yes". 73 Bob, K4TAX Ah! I've noticed this but never understood it. At least with the Globe Champ 350, the power output can increase quite a bit off resonance to the right, but the plate cu
Mike, If any of this made sense, would we be hams? John - WA1JG Im going to shoot from the hip here. I dont believe you have a PA problem. I suspect its a logic board failure. The CPU instructs many
Have you been to the Ten Tec website ? There are FAQ's about the Omni VI you might want to read. I would give their service dept a call. They will be glad to talk to you and might save you some time
Bry, Tuning the Plate control for max smoke results in dipping Ip, or at least within a few percentage points thereof. If it doesn't on your amp, there's something wrong with the amp. I will only sti
"It is a capital mistake to theorize before you have all the evidence. It biases the judgment." Jumping to an early conclusions based on the first recognizable symptom is probably the biggest mistake
