Ok working on a radio for a friend. Its in good shape and no mods done to it that I can see. Problem is I'm getting a full blown carrier with zero modulation. I cannot adjust carrier with vr pots and it doesn't matter if it's in high or low power. I already changed tr51. Took that out of circuit...

Just wondering if any has ever made up a box with a on/off switch to keep a radio keyed up while doing testing? I'm thinking about trying to put together something so that when testing on the bench I can have both hands free instead of trying to hold the ptt. Thanks

I have a 3300hp that is in very nice condition and seems to be unmolested. Problem is when powered on the only thing that comes on is the meter light. No channel display, no tx/rx light, no transmit, do hear some static in speaker though. Checked the voltage regulator and there is power there...

I got a rg-99 that has been abused. I would like to get it back to stock. Had anyone ever seen this mod before with the black box? Looks like pure hackery! Enjoy the pics. Any help is appreciated

I need to grab some Irf520 or the ekl2030 mosfets. Where is a good place to buy from these days? I see a lot for sale on eBay but don't want to get fakes. Thanks

Ok so radio is a connex 3300 zx dual final model with ept360014b board in it. Rx is just about totally gone. I can only hear a slight tone from 2040 sig gen turned all the way up. So I figured I would start to trace the the signal being injected from the antenna input over to tr17. Problem is...

I have a galaxy 94hp with a custom 4 pill amp section on the bottom. I posted about this radio needing the frequency display repaired. Well I never got all the digits to light up and starlite is out as well. I'm going to just let this go and maybe someone else can fix it. The radio still works...

Ok so the radio powers on but that's it. No carrier on am, nothing on ssb and no receive. I did notice that when keying the mic the tx/rx light doesn't turn red. It just goes out. Also the radio did die on me and then came back to life on its own. The channel display and meter light went out for...

I have a 94hp that the first 3 digits of the display went out. The last two are still lit up fine. Checked the connections, ebreveryth seemed good. Any ideas? Thanks

Hi, I have courier galaxy iv and need any and all information for this radio please. Can't seem to find any alignment info or a service manual. It's off quite a bit on ssb transmit. Making it unusable unless someone happens to tune me in. I have bk 1801 frequency counter. Just need to know what...

I would like to align this radio but cannot find the information anywhere. Any help is appreciated. It's a Midland 77-202b "black max".

I have a cobra 148 gtl Taiwan model. This radio isn't doing anything except turning on. No rx/tx/PA. When I key up the tx/rx light on front doesn't switch. Also nothing on the channel display. It's just blank. Where would you guys start on troubleshooting this? Thanks

So this galaxy 959 I just picked up is not putting out any power. No movement on my watt meter, but when I key up my test radio next to it gets a signal. Just no audio and nothing showing on watt meter. It looks like the previous owner experienced the same thing and replaced the final and...

I just got a 959 and powered it on test it. The channel display, frequency display and meter light are all not working. Seems kind of odd that they would all be burnt out on a radio not even 10 yrs old. Anything I could check to make sure I don't buy new parts for nothing?

I want to hook up my signal gen. to test it. What type of connector and test leads will I need? I believe it is a bnc, here is a picture.

I have a chance to get a bk 2040 or a bk 2050 signal generator. Which one is better? Anyone have experience with these? Thanks

Need some entry level oscope and counter suggestions. I'm trying to stay under $100. I will be using it for cb and 10 meter. I know Tektronix and HP are really good but how about tenma or Hitachi?

Can anyone tell me what a good price would be on one of these? Looking to get started in tuning, aligning of radios.

Hello, How can I hear what my radio sounds like on transmit? I would like to actually hear for myself instead of just asking for a "radio check" over the air and seeing what people say. What piece of equipment do I need or can I use another cb I have laying around?
