Bend it back very slowly, I have worked on a few aluminum antennas that have had bent elements and they tend to kink very easy.

I purchased an extra whip for my Wilson 5000 and cut it for 10 meters the one for CB is centered in the middle of the band CH19 will work up to about 27.7xxx with an SWR right about 2.1. If you working both bands probably an extra whip is the cheapest way to go and it only take a few seconds to...

The new LED street lights in my neighborhood give me 2-S units of noise after dark on the 10 meter band

That would be nice to listen to.

There is a collection of them out there and I heard most of them mentioned in this thread here in CA. there was another one out there that kept saying: CQ CQ Alcida but I have not heard him for a month or so now.

Nice amp I had one back in the 80’s but I believe the tubes are no longer available. I have a TL922 I may part with.

Nice:D

please correct me if I am wrong, In my mind its not an alignment issue for following reasons (1) everything works normal both TX/RX on all modes except no TX output on Uppers side band. (2) There is defiantly the smell of something that had got hot or burned in the radio but don’t see any visual...

Sorry of the double post

Looking for some advice on servicing a President Grant CB this is and older one probably around 1977. I have searched around on the net for documentation but the best I have come up with is a blurry schematic diagram, the problem is as follows. No output power on Upper Side Band, but I can...

Hay thanks for posting photos! Look like the main matching network has more open hoops by compared to the original (see photo below) maybe the new ones have a more band with??? Looks nice.

When you get some time please post a few pics of the antenna, I am curious if they use the same matching network design like the original one.

You have a good eye for antennas one photo has a Penatrator the other is later photo with a gain master.

I have done a few antenna in the tree set ups over the years, I use back to back strut and size the clamps that go around the tree. Strut is used in the electrical and plumbing fields so if you know someone you might get some for free, if not it can be purchased.

Perfect!! thanks for the information guys. Yeah the receiver needs some attention I am measuring about 3uv @ 10db sinad not very sensitive, a local guy brought me the radio to take a look at for him it will be nice to get it done and off the bench. Thanks again.

That is helpful info to get in on frequency, but do you by chance have the complete receiver tune up info? The main problem is the receiver has poor sensitivity.

Anyone by chance have the complete alignment info for both the TX and RX for the cobra 139xlr? the receiver on this radio is a bit numb and want to go through the whole thing. Thanks
