I would like to use an IC-706 to drive an ALS-500M. Pin 3 of the 706 accessory socket goes to ground on transmit, but it apparently can only sink 20mA. The ALS-500M manual says that the T/R switching
Fidel, there was a discussion of the ideal relays to use for this kind of application on the TowerTalk list several months back. Although there were some opinions that Radio Shack's typical relays we
The MFJ-Mirage web site doesn't have this schematic. Mirage was kind enough to fax me one, but it's quite blurry. I wonder if anyone has a copy out there and can e-mail or fax a clear copy? 73, Joe _
Actually, with the screen supply mod they'll deliver about 1.5 KW, albeit with a lot of humming. You can buy them for about $1300 or so...unless demand from JA has driven up the prices. 73, Joe R.Mea
I'll second that! A real bargain at current prices! 73, Joe bob finger wrote: Bud: To me a good choice that satisfies all but your auto bandswitching is the Ten Tec 425. For your #5 simply leave it i
Yes, I was surprised to discover that FedEx's ground rates are, in some cases, almost 50% lower than the USPS. 73, Joe _______________________________________________ Amps mailing list Amps@contestin
There is a Tempo 2002 2M AMP AVAILABLE WITH A SPARE PAIR OF NEW 8874'S. Apparently, it'll put out about 750W with 25W drive. It seems to be about 20 years old or so. Does anyone have any comments on
Bill, I once used one for about a year. I never got any reports of a bad CW note nor did I detect any problem when I personally monitored the signal. 73, Joe _________________________________________
I have an opportunity to pick up an Arcos 2M Amp built by W2GN in the 80's. It uses a pair of 3CX800's for 1.5 KW output. It also has a dual channel Bird wattmeter for simultaneous measurement of for
I am currently using a DEMI 6M transverter with my Orion to drive a VHF-1200 to about 400W output. The DEMI puts out about 20W which can be reduced, if necessary, by reducing the drive from the Orion
Roberto, many thanks for the recommendation. Looks like a bargain. 73, Joe _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.com/mailman/li
Jerry, there is a well known and simple screen voltage mod that allows one to run 1.5 KW output. The power trans hums a bit, but I did it for years w/o any problems. I sold my 30S1 together with my f
I am trying to stay calm.... I am trying to open up the cabinet on my Command VHF-1200. It uses screws with recessed hex heads. I was able to remove some of them, but some seemed to be put in extra t
I can only say that I am quite happy with my Titan 425s. Two years is not very old if the tubes have not been abused. $1500-1800 would be a fair price depending on overall condition including tubes.
When I was at Dayton a few years back, I met a guy who claimed to be the original designer of the TenTec Titan 425. I believe he said his name was Ron and his call was N or K4X? or something similar.
I need the blower motor with or without the squirrel cage assembly from a Titan 425 amp. I am trying to locate a source of replacement motors, and I would like to show a sample to any prospective sup
I also have had an order in for this motor for more than a month, which appears to be identical to the blower motor in the TT Titan 425. The Alpha part number is BLX-X129 and it is manufactured by Mc
Bill, I recently purchased a blower motor from an Alpha 86. It appears identical to the motor in my Titan 425. The specs for the Titan blower and motor are 60 CFM and 3000 rpm. Alpha should be able t
Bob, I have used a DEM transverter with my Orion I to drive a Mirage 1016G Brick by itself. By reducing the drive to the brick, I have also driven a Command 6M amp to about 800W out. The transverter
TenTec uses double sided tape to hold the multipurpose meter in the Titan 425 front panel. Although I love the amp, I was not impressed by that method of mounting. OTOH, it seems to work. 73, Joe K2X
