Something you did is touching chassis ground that shouldn't be. You are concentrating on the amp and how it affects the setup. You don't need to. Do this little test. Run the radio straight to the antenna like you said. It works now right? Now, take a jumper and run the ground from the power...

I think you should re-read W5LZ's post. What you saw, and what he said are two different things. The most pertinent part his post as it applies to an input or output transformer in an RF amplifier is the first half of the first line. Mopar

I'm not sure what you're getting at freecell. Didn't QRN say what is going on here with this post? Or, are you talking about something else that is going on that we are missing? Mopar

Sleepwalker is talking about a wire going to TR39. Leave TR39 in place, just cut the wire or put a switch in it if you wish. http://cbtricks.com/radios/galaxy/dx33hml/dx33hml_talkback_mod.htm Mopar

I think you are right Librium. If you look around, you won't find any negative posts there. Another thing you don't regularly see there are technical answers posted by the shops. They seem to avoid those questions like the plague. Here, freecell, SS8541, DTB and others that own shops...

"this noise and rec. is the same with truck running or stop with key off." If you have a power inverter, turn it off. The problem you are describing with truck on or off, different antennas, different radios, etc. would lead me to believe that you have something running in the truck all the...

I believe the other reason that it needs to be a an odd multiple of a quarter wave per side is that if this is used, both antennas will be forced to have equal currents and in be in phase even if the loads are not perfectly matched in impedance. If this isn't used, the whole idea of using a...

As I previously mentioned, that will only work if the board doesn't need 12v to complete the receive circuit. If the radio is of the type that needs ground on one pin of the mic plug to have receive, then this may not work because some beep boards have a relay that is energized when you are...

QRN pretty much covered it but I will put in my two cents. You -may- not be able to simply disconnect power to the board depending on the board and what radio it is installed in. If this is the case you will have to follow QRN's second suggestion. If this is the case, just put a switch in...

Your link is not pointing to any particular item. If you are considering a dipole, don't buy one, make it. If you don't know how, just search "homebrew dipole" on the net. Easy stuff and super cheap. Mopar

Thanks Beetle. Hey, love your signature. Too funny! Mopar

Thanks Switch Kit! Mopar

I have read manuals for setting up military grade (URM) equipment and you are correct Beetle, they all had very stringent rules for proper alignment. However, it doesn't seem that those rules were always followed. I would imagine that there were many military techs that weren't issued the proper...

2M Guy makes a great point. I guess it depends on why you are trying to get an exact measurement. I have a friend whose dad worked on the radios in Hawaii at the military airbase there. He worked on both the Air Traffic Controllers radios and the ones in the airplanes. When they tuned the...

Reverse polarity diode? D105. Why is your power supply not blowing the fuse you have in line with the radio? You are running a fuse aren't you? You may want to address that issue first. Mopar

If you have any old coax laying around, the braid from that will work just fine. It is too big IMO for radio work in general, but you are just looking for something to desolder one component. If you don't have that, you can get by without desoldering at all. Just use a pliers and gently pull...

I liked the article that you wrote about the V58 so much Master Chief, I saved it. Here it is.... Thanks for taking to write that Master Chief! It is very helpful! Mopar

I have a question for you lords. I have been doing a little light reading and came across the following in an article about MOSFET's. What is your opinion of this quote? “Power MOSFETs have been replacing power BJTs in power application due to faster switching capability and ease of drive...
