Upon investigation, it seems that one or more of the Astrons shuts down so not all four sections of the amp are powered. I see that, if I turn off one supply, that there is backfeed from the amp show
Some of Ten-Tec's filters have both the model number and the stock code stamped on them. Some have only the model number. Most I have seen have only the stock code. In many cases only some portion of
Hi Bob, Are you using the Johnson Matchbox to go from unbalanced (coax) line to balanced, and then your balanced L net between the feedline and the Johnson? I suspect not, but then what are you using
ANTENNA TUNERS ARE LIKE GOING TO THE DENTIST... Nobody wants to go there, but if you have to, you're really glad they are there. And you really don't want one that is not a good one.
There are not many parts in those filters. If you draw out the schematic by looking at the PCB traces you can reason out which parts could fail in a shorted mode, or in an open circuit mode, and caus
The Omni VI has a 20 MHz reference oscillator (which is divided down to 10 MHz) to which the VFO and the band switching crystal oscillators are locked. The BFO crystal oscillator is not locked to any
And don't forget, you can also speak LOUDER AND S L O W E R to someone whose native tongue is not the language you are speaking in. It doesn't help any, but it is common practice. Oh...I see...All CA
Ignore and delete immediately if off topic posts offend you. I am looking for a schematic of a Hammarlund SP-600 modified by Northern Radio. I have "stock" SP-600 schematics, but this modification ha
Here is the way Field Day works around these parts, which is the Hilo side of the Big Island of Hawaii. 1) At a club meeting a month or two before the event, the subject of Field day is brought up. T
Hi Lloyd, There has been a discussion on the Ten-Tec email reflector going on for the past week. A lot of complaining about operators who don't know how to operate and other stuff. I couldn't resist
Hi Jim, Hmm...is this the sort of Field Day that I can look forward to if we move to Volcano in a few years? Yes it is if you operate with BIARC and things don't change. Maybe I should operate solo f
Gee, Ken. Your rendition sounds credible and accurate - especially describing the ebb and flow of attendees - but I am surprised that some of the guys actually return for tear down. Their stock sure
In short: there is no easy, straightforward way out of this. Stuff like this is relatively rare and on a par with low-end lightning damage, so there is no cookbook answer to what might have been dest
If we start now, maybe in 5 years we could get some legislation, and maybe in 15 years the bands will finally be cleaner. There is no situation so bad that it cannot be made worse with government hel
Correct and the accepted definition of Dual Conversion in the world of Superhetrodyne receiver design would be a radio with two distinct RF frequency IF's before detection or demodulation to audio. A
I am not entirely sure what it is I am trying to achieve with the scope and not sure what they mean by triming r1 for mixer balance at 21.320. I cannot say anything specifically about the Argosy. Gen
