Just last night picked up a Texas star dx 350 hd from a driver getting out of trucking for $100. Seems to work well with no obvious dents,scratches etc. The inside looks practically new also,with no odor of any burnt components. He had it on & was using it while selling. Sounded good without it...
Ok I know that some will say its not worth it before I begin! I was wondering when adding the 2nd mosfet to a 949/959.... On cbtricks its going off of the 1969 version it really doesn't show biasing the 2nd mosfet with a companion part. Wouldn't it need the same biasing. Just curios!!! Now I...
Ok I just bought this recently for $50. After opening it up & paying more attention to it, I found out its the HP model with dual finals. I have seen elsewhere tuning locations for the one with a single final. Can anyone shows or guide me in the correct direction as if the same tuning points are...
I have the galaxy dx 949 (mosfet version) I have very low modulation on AM but seems to work well on ssb swinging up to 18w. On AM deadkeying 1won low power swinging 1.5w .on showing about 4% modulation on 949 meter & also checked the same with an inline to verify. Thank you for any help or...
Does anyone happen to know the value of q24 a uniden grantt xl with the mb8719 chip in it?? I'm hearing that the sound is clear but not very loud.. Could this be caused by that transistor missing or could it be something else.. If my understanding is correct, that transistor is another part of...
I get about a 2db gain over the factory antenna. Setup both having 1.1 kit was made using 2 k 40 adjustable tip,1" PVC with caps. 4" of copper wire for the ground between the 2.
Ok! I have done the mosfet conversion with "peak&tune". Here's the deal! I have also done the talkback mod where you solder the top of the 2 resistors together to make it louder & for some reason I just noticed today that when I am just listening, if I turn the talkback all the way up, it...
Just a thought bouncing round in my head.. using 2 top loaded antennas with a T mount. Is it possible? How well would it work? Would it outperform a single mirror mount topload antenna? Just trying to learn a little bit. I have read n seen the videos of how to make several different styles n how...
Ok I did end up purchasing. It. It came with the "channel mod" . Yes it is the 5 pin side mic .it has the 2166 driver with they 1969 final. (Made in the Malaysia) stamp date is 1995. So far I have had some great audio reports on Am but I still need to get it to a shop to make sure that...
Having. A hard time finding what the issue iswith the radio. I have the schematics. But would like to know what the volts/amps should be for comparrison
. Thank you for any help. I have changed q54/55/37 both driver & final. Biasing volts at the 520's are 3.86v.. still has no carrier,no output...
Has no carrier,no modulation. There is modulation in the fallback but not on transmit. I have replaced q37/q54&55 with like part. Showing 11.84 volts @ source side of q55 &.12 volts on gate side. Only showing. 07 @ drain of same transistor. I checked the transistors.with a meter before...
Ok!! On cbtricks it shows & tells the place to add the 4.7k resistor. Would it change anything if you were to add/subtract the value of the 4.7k? 10k or 2k.... would it change the value of the 10kc mod to a ??? 20 kc/5 kc mod... new to the electronics & am trying to learn. Thank youyou
Nte153 = 2sa1012 upgrade @ q37.......nte2382=irf520 @q47/49.....nte37=2sb847 upgrade @q54/55... the reason I am asking is because these are easily available to me ....next town over
