I also have a Johnson (well OK, a Nye Viking *identical* clone) 250 watt matchbox with SWR bridge. As these were fairly beefy and built in the AM days, does anyone know what power it can take on SSB,
I guess it depends on the vintage. Mine came from the factory with the board already installed. It was a "Revision B" board. Very early Centurions may not have had it at all. The rev B board blew up
Dave, A beautiful job....thanks for sharing the pictures with us. However, a couple of questions: Did you test the central vac pipe in a microwave oven to make sure it's not the kind of plastic pipe
I could be wrong, but I thought the whole thrust of the ARRL argument to get this frequency assignment was for emergency/hurricane/storm (Caribbean?) communications when propagation was too short/too
Duane, I agree with you...unfortunately, the radio manufactures have not yet reached that exalted state. I respectfully disagree, at least as long as *many* operators are clueless as to how to proper
Group, I'm using an Omni VI+ (Option 3) and just completed building the Idiom Press "CMOS Super Keyer III" kit (built into a WBL paddle, but that's another story). The keyer has a "K" parameter that
Bob, The tuner should generally be within a few feet of the transmitter. If you can arrange to use the dipole with the tuner close to the rig, you should find that it will perform better than your wh
Ken, I have an Omni 6+, not a Jupiter so I'm not sure how it's constructed, but is it possible to just pull out the EPROM chip (or even the card the chip is on) and send that to TT rather than the en
Bill, I've experienced the same problem with my Omni 6+ 250 Hz filter in the past. It most likely has nothing to do with a defective filter or the narrow bandpass (although anything can go bad). The
Well group, I'm probably just getting grumpy in my old age and /or have too much time on my hands. Anyway, here is my pet peeve: When someone is selling something on this reflector, many times it is
Well, at least for my Centurion (I'm the second owner, amp built in '93 or '94 [?]), the answer is: yes and no. It all depends on how you define "in-rush protection". To my understanding, that phrase
<snip> <snip> OOoooooh, nooooo. It sounds like Joe is saying that the Jupiter is more susceptible to RF than the ICOM. I hope this is not a portent of things to come with the Orion... 73/Carter/K8VT
Always good advice!!! :-) I agree... I disagree. My Omni 6+ is very susceptible to RF. Yes, I have 450 ohm ladder line coming into the shack and yes there are unequal currents flowing in each leg (i.
In theory, you are absolutely right; however, in practice, (unless you are very lucky), it is almost never balanced. One end is closer to a tree or a fence or a roof or whatever. There is darned litt
Mike, Whoever told you that had to be pulling your leg, right? I don't know about Easy Off specifically, but in general, oven cleaners are EXTREMELY strong and used to contain lye (nasty stuff). Thin
Preamble/Disclaimer: Before you turn on your flame throwers, I love TT and have been a (mostly-see below) happy owner of an Omni VI+ (Option 3) and Centurion since 1994 and will most likely upgrade t
