Was hoping someone could steer me in the right direction on finding a 10 turn pot that would work on a old school 148 GTL's clarifier , one that might fit one way or the other. Much thanks ! Switch Kit
I've heard it said over the years that MRF 454's are a true side band transistor .........Can someone explain to me why this is ? ........are they any truer then the Toshiba's or any other transistors along those lines ? Is there something that makes the MRF 454's special when it comes to SSB...
This radio has been recapped , the power off the dual 1969 transistors is great and the alignment is right on the money . The problem is when you turn the radio on you hear static coming in with the volume turned all the way down with or without antenna or dummy load connected ? As you turn the...
Can't seem to turn the audio down on this one ? in other words , you only need to just crack the mic gain control on AM or SSB using a stock mic ? I really don't know , VR6 doesn't look like it was ever in this radio and there seems to be a jumper across where it would have been . As far as I...
I'm thinking another oldie but goodie ? Face place and switch was caved in and damaged in shipping , was able to change the switch and bend things around and get it going. Was told sounded good on SSB (AB?) and AM ..........single mosfet driven Grant LT , 1 to 20 on AM and 20 on SSB . (no clips)...
The amp has very good SWR's on low and medium power on both antenna and dummy load , the problem is when it's on the high side SWR is in the red ! both on dummy load and antenna ? It's weird because it's very good on the other settings ? Thanks . Switch
Just was wondering if anyone has used one of these and what they thought about it ? I'm surely no amp expert but it looks AB and kind of resembles maybe a older Messenger amp ? I would certainly think it could do a clean 300 watts with 4 x 1446's ? Thanks
Wilson 5K load on a Wilson 1K mag mount (RG58) on a 2 by 3 foot metal table on porch 15 feet off the ground used with a K40 / 58 inch stinger (because it "appeared" to match better then the Wilson's) I'm guessing RF is traveling the outside of the coax because moving wires , radio or coax inside...
It's been a handful of years for me and I'm looking to buy me a brand new radio for a change . (Been out of the loop for a while now) From what I have read both the Q6's & PL2+'s are decent affordable radios . Was just wondering what you guys might think ? or if one is that much better then the...
Amp looks very similar to the old Messenger line of amps . Up front , amp is a little buggy but works OK , medium side is out and the max side produces a very large DK ......with 2 watts in Low side does about 25 to 120 and High side does about 50 to 200 pep ......the SRF 2072's are 65 watt...
The meter is in very good condition and works as it should . Very solid piece of equipment. 5 to 1500 watts. 50 dollars shipped Priority Mail . Paypal works. Ship same day or next. Thanks for looking.
Radio is in good condition , Variable drive on the RF Gain Control (rf Gain is wired wide open).....Goes from 1 watt to 5 watts and swings just over 20 from any setting. No clips in this radio ! audio is good on it's own stock mic , turn it down to run your favorite amp ? all the audio you would...
FC-347 wired in freq counter , TRB-x2 echo board , (swr meter switch tied off in radio) very light talkback for echo board. Center slot aligned with 6 down and 4 up , solid drift free sideband. Tuned low on AM about 2 to 18 pep and 18 pep on SSB (there are no clips in this radio what so ever !)...
Second generation 25 LTD with TRB-1 echo board very light talk back applied (RF Gain is wide open and the control is tide off in the radio), with AB Galaxy 80 amp ( MRF455) radio is set at 1.5 watt dk with a 20 watt pep audio swing ,can be set anywhere you want it (diode inline) NO CLIPs ! into...
Radio has pretty good cosmetics , bracket / knobs and power cord , RK-56 NC Mic and very decent FC-250 inline freq counter. No clips what so ever in radio ! Swing diode inline for AM , will swing around 18 from any setting , (radio is set at 2 watts swings from there) Open clarifier RX/TX...
Another one of my oldies but goodies in a Cobra 140GTL . All works as it should. Solid drift free SSB. RX/TX open on the voice lock about 3khz up and down center slot aligned. This radio makes for a nice mobile but also will do very well used for a base station. Same board as the Cobra 142 GTL...
First run Cobra 148GTL .Solid drift free sidebander, Only thing done to radio was clarifier opened for RX and TX. (about 3 khz both ways) and a diode added for AM swing from any power setting. (NO CLIPS !) Center slot aligned . It's set at about 18 watts SSB and 2 to 18 on AM. They don't make'um...
