Jim, TNX for the info. Does it matter whether the THHN is solid or stranded? What core size do you recommend (I'm guessing 2" or so)? Also, (purely from a "dumb questions dept." perspective) would a
Clearing out the excess stock: 217 (500 Hz) and 219 (250 Hz) 9 MHz filters, tested in the "ALalyzer Analyzer" (Argosy) and seem to work as they should. $60 each shipped CONUS or $110 for the pair shi
I wouldn't totally discount the possibility of RF sneaking back in where it wasn't supposed to - the cable to the footswitch could be functioning as a "Murphy"* antenna. Might a snap-on ferrite choke
Wade, You gotta give these folks some slack - they may not be able to move because they have special XTAL control rigs just for the net frequency HI HI!! (Or maybe their tuning knob is stuck???) 73,
Maybe apples and oranges, but I seem to remember a thread (or conversation with TT service?) back when about display noise being related to bypass cap issues on the Omni-Ds - I'd guess the same might
Wonder if the guys at the factory are listening? -- Press Release from "Pseudo Ten-Tek Inc." (Undated, sometime in the future) - We at Pseudo Ten-Tek (hereafter PTT) pride ourselves on listening to o
I've seen the RIT/offset circuit cause this kind of issue. The offset trim pot may need to be readjusted. The procedure is in the manual on page 3-39 (at least on the copy that's posted on TT's websi
Rick, TNX for the spreadsheet - it's an interesting read. What I gleaned in a quick analysis is that while they aren't as convenient, the "old school" link-coupled tuners (in this case, the Johnson M
Phil, This fellow seems to be pretty heavily into repairing the old Argonauts: http://www.earlandrews.com/argonot1.html Maybe he could shed some light on what to look for.
What I find interesting (if I'm reading Sherwood's chart correctly) is that the Corsair (other than filter ultimate rejection) and Omni V come in very close to a statistical dead heat with the Omni V
Mike, Before blaming the filter try tuning around and/or move the passband tuning control (PBT) back and forth a bit. The 282 has an extremely narrow peak and can sound like there's nothing there if
Roger, The 48057 is the stock 4 pole 2.4 KHz filter used in the 9 MHz IF of the Argosy and Corsair (560, not the 561 Corsair II.) The model 220 (or 48058) is the 8 pole version and is a "drop-in" rep
Looking for an Argosy (analog or digital) "basket case" or parts rig. Please provide info on failure event or symptoms, physical/electrical condition, serial number, whether unit is "as failed" or if
Bob, Point (2) is well taken. Back in the days of "vinyl" when I worked in small market radio I could hear when a stylus was getting "edgy" (chipped or worn); it had the same effect on me as a chalkb
Others may differ with my advice, but I'm not sure you really need to "finish the alphabet" before you start listening. As a suggestion, start listening to W1AW's code practice sessions - even the "h
One other thing (which can be a source of controversy for some folks): I was emphatically told (by my now SK dad who was first licensed in 1934 and served as a seagoing radio op in the Coast Guard du
Rick, Funny you should mention "sending with anything" - in one of my typical "oddball" moments I made a single-lever "picopaddle" out of a tiny SPDT contact assembly I salvaged out of a defunct CD-R
To borrow from an old quip: any fool can work DX with a kilowatt amp and a big antenna. It takes talent to do it with LPCA (Low Power, Crummy Antenna.) 73, Al
