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 TT overvoltage crowbar kit for a 252/262 PS that they never got around to installing? Haven't checked for availability from TT, but have to believe they're LONG ago obsoleted and n
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
Carl, Is that really true? Aren't the 218 and 219 employed as roofing filters in the 1st IF, and isn't the DSP BW control in the 3rd IF? If strong adjacent (and/or dirty) signal conditions warrant ti
Thanks to all for generously sharing your knowledge. That generosity sure adds to the enjoyment and satisfaction of Ten Tec ownership...and the hobby itself. Tnx agn es 73, Allen--W7GIF -- Original M
You might try KE9PQ who frequently lists Paragon subassemblies/parts on a large auction website. His email can be found on QRZ. I have no affiliation with KE9PQ or his operations/business. Allen--W7G
Might be worth checking with Gary Follett W0DNV...on both counts. I recently got got a "no longer available" ORION VFO encoder from him...priced right, shipped well and quickly, and 100% functional.
Oops. Gary's call sign is W0DVN (not DNV). I'm not really dyslexic...but, confess to carelessness with the keystrokes. Allen--W7GIF -- Original Message -- From: A R<mailto:raf_3@msn.com> To: Discussi
The Corsair II was equipped bare-stock with two 8-pole 2.4KHz filters: One in the 9MHz 1st IF (on the 81252 XTAL FILTER board), and One in the 6.3MHz 2nd IF (on the 80979 PBT board). The 9MHz cf 2.4K
My 565 Orion has the A14 autotuner, which has no battery. Although the manual calls out a p/n 81956, the A14 board in my Orion carries only marking: "LDG RG-11". Did TT equip Orions with (at least) t
Tony, Before you remove all those torx-head screws...my 565 has the LDG RG-11 autotuner which has no battery. Allen--W7GIF -- Original Message -- From: Tony Lelieveld<mailto:va3dwi@gmail.com> To: Dis
Hehehe...that's just what I did after the first R&R...&R. I'm glad that I'm in good company on at least one account. Allen--W7GIF -- Original Message -- Sent: Saturday, January 16, 2016 5:14 PM Subje
Oops. The LDG part/model number is RT-11 (not RG-11). I'll blame that one on clumsy fingers. Allen--W7GIF -- Original Message -- Sent: Saturday, January 16, 2016 4:55 PM Tony, Before you remove all t
Does anyone have a Centurion QSK board (p/n 78247) that's surplus to their needs? If so, please contact me off list. Tnx es 73, Allen--W7GIF _______________________________________________ TenTec mai
