Recently acquired an estate Argosy 525 with the 225 p/s. After a thorough cleaning (dust) and replacing the broken dial cord*, it's working well, except for occasionally going deaf upon power-up. Hit
Thanks, Al. Yeah, it's a pretty simple circuit. I recalled discussion some months ago regarding the kit that TT offered as being compact and easily fit into the 252. So thought it at least worth tryi
Thanks, Mike. Time to build a couple to prevent vaporizing my Triton or OMNI-C. I'm fortunate that to date I've escaped Murphy's wrath. 73, Allen -- Original Message -- From: Mike Stricker via TenTec
Al, Yeah, I checked the spec's for the TT 218 (1.8KHz) and TT 220 (2.4KHz) filters, and surprisingly the insertion loss for the 218 is marginally lower (.2 dB) than that of the 220. Since my goal is
Welcome to the lead-free world of RoHS. Your spools of 60/40 solder are NOT RoHS-compliant...but will likely improve reliability of solder connections which are subjected to the stresses of expansion
QSL. In my former life in military and space electronics, I spent many hundreds of hours chasing RoHS-induced problems (today they're called "issues"), including the microscopic fracturing of solder
In my experience, yes. There are or have been a number of lead-free alloys developed to try to mitigate the problems arising from loss of the ductility properties of lead alloys. It's also true that
That's a question that TT should be able to answer. The RoHS Directive was officially put into force in late 2002 or early 2003. But, some (many?) manufacturers were made aware of the impending/propo
Does anyone have a Studio One mic with a 4-pin mic connector-equipped cable available? Looking to replace the 705 currently on my 565 Orion. Please contact me off list. Thanks and 73, Allen--W7GIF
DigiKey definitely has them. Their p/n 497-3689-5-ND is the 48mah, 497-3690-5-ND is the 120mah. The 120mah SNAPHAT fits/works well in the 565 Orion. 73, Allen--W7GIF -- Original Message -- From: Scot
Dave, My OMNI V is I think an '89 production (s/n 63A10699), and like yours has the 8-pin U8 RAM. The hold-up battery is an easily replaceable 3v CR2032 Lithium which I replaced about 2 years ago whe
My recently acquired ORION 565 is one great radio, but has one annoying trait. Upon power-up, the panel-mounted VFO A encoder ignores rotational travel over about a 180 degree arc. The dead area of a
Mike and Barry: Yikes! No "MULTI" control would be a definite PITA. Given the symptoms, the connector interface integrity sure makes a whole lot more sense than a problem with the encoder itself. I'm
Does anyone have any "spare" pushbuttons for an OMNI V or OMNI VI? I have a need for the "REV", "A=B" and "A/B" pushbuttons. Checked with TT, and they can't help. The silk-screened legend/characters
Recently acquired a nice OMNI VI Plus-OPT 3, and have disposed of all issues except for an inop VOX function. In fact, the VOX misbehaves. When the VOX pushbutton is pressed, I get the VOX lamp lit,
I've run across two 425's, each with different front panel color schemes and knob styles. fine-serrated tune and load knobs, and no 10m legend marked on the panel. Front panel is marked "TITAN" (no 4
Thanks Barry. That link was really useful. It looks like the #1 amp in question is the third production variant described on the ref link. Owner says the nameplate specifies Model 425, s/n 91A10160.
I believe they're Chinese mfg branded "TAYLOR". Can't speak to their life or reliability. 3CX800A7's are cheaper than I remember. When I blew up the ones in my Titan through grievous operator error,
Does anyone know of a source for a suitable replacement for the 60 microHenry plate choke for a TITAN 425? The guys at Sevierville can't help. Thanks....
Thanks to all for the leads and suggestions. My first thought was to rewind the damaged choke, since the core/form is still good. Actually, although the choke has obviously been overheated and I can
