    Volting a Cobra 148 GTL final?

    Hi loosecannon, I know this an old thread but what would you consider the most effective way to get 12v over to tp7? I know this only gives about and additional 10w pep out of the 148 but that would make a considerable difference in driving my Texas Star 500V. After a proper peak and alignment...

    where is the input tuning cap located

    Unfortunately, I don't have an SA nor the technical knowledge to diagnose that deeply. But when connected to a 50ohm dummy load, the amp will run with only about a half watt reflected power. I have a very good match...less than 1.1:1 on my 5/8 ground plane. As soon as I go through the antenna...

    where is the input tuning cap located

    I know this is an ancient thread but after tuning the mica cap to achieve lowest reflected power I find that the output of my amp decreases by about 60w. Don't get me wrong, I'm fine with that as long as that's normal and not bad for the amps circuit. Had anyone else experienced this? Thanks

    Cobra 148 GTL variable deadkey mod

    I live in an area where there really aren't any locals for which I would have need for the rf gain feature so I was actually considering using that pot instead. That's how I have my 29 LTD set up. That being said, I always considered in radio swr features to be all but useless so, as you say...

    Cobra 148 GTL variable deadkey mod

    Thanks for the info! This radio is untouched still in the box so I don't want to hack the crap out of it but I do need a variable output to tune it to my amp. You've given clear and detailed instructions so I should be able to get through the mod but if you ever do get around to taking pics of...

    Cobra 148 GTL variable deadkey mod

    Hi all, I couldn't find a direct answer to this anywhere so I apologize in advance if this topic is in another thread that I may have overlooked. I need to get a variable deadkey on my 148 GTL. I would like to tie it into my rf gain pot if possible. Can this be done to a 148 or no? I have it on...

    11 meter is very quiet?

    Great skip this afternoon. Made it from New Hampshire to Santa Domingo on 37 LSB. Crystal clear QSO for 10 minutes or so.

    11 meter is very quiet?

    With the exception of one day last week, haven't heard a soul, except for a few locals in the am, for over two months up here in New Hampshire. Very sad...

    Texas Star Amp Repair free help

    As far as contact info goes, if you call Galaxy/Texas Star support they will get you in touch with Mike. And loosecannon, the only thing that I can tell you is that the latest repair work that Mike did on my 500V, he used DEI pills on the rebuild. He also mentioned that some customers had...

    Texas Star Amp Repair free help

    I spoke with him before I saw the post so I haven't told him yet. He will get a kick out of it i'm sure. It will also probably make him feel pretty good as well, knowing the kind words spoken about him and maybe even get him to get on here and wave a hand. He sure is a fountain of knowledge when...

    Texas Star Amp Repair free help

    Just a quick update. Mike is alive and well and still the main Texas Star repair tech. He's just been busy as a beaver as they're grossly understaffed over at TS right now. Just happened to see everybody was getting ready to write his obituary lol. Talked to him yesterday.

    Sirio 827 base antennae issue

    Hopefully my 827 does not develop the open loop issue in the future. The odd thing is that I did notice that the reflected wattage would jump quite a bit as I climbed closer to the upper part of the band. But without the amp on there was not much difference at all in reflected power. As a test I...

    Sirio 827 base antennae issue

    You could very well be correct. Swr is no higher than 1.2:1 but when I turn on the amp it goes up a bit to 1.4:1 or so, at the highest. However when modulating it goes back down to 1.2:1 or below. I'm using a Palstar cross meter and it reads +/- 5 watts to my friends Bird meter so I know it's...

    Sirio 827 base antennae issue

    Hi all, not even sure if there is an issue or not with this antenae. After assembling this antennae I checked for any shorts. I was getting full continuity between center pin and SO-239 at antennae base. I called Sirio support and was told this was normal because this is a DC grounded antennae...

    Cobra 29 ltd faceplate removal

    I have used Spaz Stix on other hobby jobs and I can tell you it's some great paint with very cool effects. I can't see why it wouldn't work well on the plastic bezel. Just make sure that you use the proper backing color depending on what paint you use for the right effect. 73

    Cobra 29 ltd faceplate removal

    Nomad, finally got it apart. Indeed, they used hot glue to hold the led board to the rear of the bezel. Man that made it difficult to disassemble! Goes to show that you never can tell with these 29s. So many slight variations to them. If anybody else runs into this, just use a sharp X-acto blade...

    Cobra 29 ltd faceplate removal

    I did take the nut off which frees up the selector itself but it seems that the channel led display and the tx/rx and ant warning light are glued to the plastic bezel. At least that how it seems.

    Cobra 29 ltd faceplate removal

    This is a very old thread but I'm hoping that someone can help me on this. I'm trying to replace my scratched up bezel on a Cobra 29 ltd Classic and I'm having a very hard time. I've read all the advice previous but none of it helps. I've removed all the screws which attach the plastic bezel to...

    Cobra 29 wx st mod

    I kind of got it where I thought it sounded nice and loud but no obvious distortion, at least by my ear. At that point I threw it on the scope and took those screenshots. I'm happy with it right about there. I can push it a little more without the positive peaks flattening out but no need to go...
