    RF Gain Control up, "S" meter goes down, WHY??

    Beetle hit the nail on the head. From page 21 of the operation manual: If your transceiver is configured for “RF Gain” use, rotating this control fully clockwise in the SSB/CW/Digital modes will provide best sensitivity. To reduce the receiver’s RF Gain somewhat, rotate this control...

    strain relief mic cord boot

    Another option is a rubber grommet. When you tighten the case screws the grommet will apply pressure against the cord and hold it firmly in place. ;)

    Antenna 101?

    X2 The ARRL also offers books that contain various antenna designs and instructions on how to build them. Another option is to do an online search for the particular type of antenna you want to build, such as a dipole. There are several websites offering antenna information. Here are a couple...

    How to bring down mobile voltage?

    Did you measure the voltage or are you going off of the voltage gauge in the dash? The dash gauge does a good job of telling you whether you are charging/discharging but may not indicate voltage accurately. A good example of this is the gauge in my Blazer. It indicates a charging voltage of 15v...

    Top Gun Modulator

    I don't care for the audio quality with the CP-1 engaged - sounded a bit more distorted to me. Maybe that could be resolved by not running the gain on the radio wide open? Since it was mentioned that (in SSB mode) some of the peaks were reduced but no noticable increase of average talk power was...

    Wilson 5000 Magnet Mount Coax

    I had similar results about 3 yars ago when I replaced the coax on my Wilson 1000 (roof mount) with LMR-240UF coax. No trimming of the whip was needed, in fact I had to extend the whip a hair but SWR was =< 1.2:1 across the entire 11m band.

    Capacitance Hat's Don't add Audio

    I think a key point was overlooked in the quoted material (see underlined above). The ease of matching an antenna is only a portion of what's necessary for it to perform efficiently. A dummy load will provide an excellent match, but is a terrible radiator. Resonance and TOA play a major role in...

    Opinion on Copper.com's "expand, align and tune"

    I know from personal experience that Copper sold refurbs as new. I don't know if they still do - I won't buy from them anymore - but I got stuck with one back in the 80's. I also got stuck with a fake (pink box) Cobra when I was told by them up front it was a genuine Cobra product. :angry:

    Another New Guy needs help....

    Good luck on your test(s) - I'm sure you will do fine. Perhaps the president of the radio club knows some VEs in the area? Maybe they can arange to meet and test you so you don't have to travel as far...

    Power supply experts needed

    Personally, I wouldn't try it with mismatched supplies. Limiting diodes and (as Shockwave mentioned) making sure the output voltage from both supplies is the same is critical in making the supplies work together. Some of the Astron supplies have the needed circuitry already built into them. They...

    Question about making a dipole antenna

    This article may be of interest to you. It might reduce the number of times you have to put up/take down the dipole for tuning. Good luck & have fun...

    Rude Ham welcomes new guy on Christmas 2010

    If he was on this forum it was before my time, but I agree that it's the same person. Frankly, I find a lot of his 38lsb antics comical. He can really get some of them going... :biggrin:

    Power supply experts needed

    Exactly - the higher amperage supply will try to handle the entire load. When it does it will dump high current into the smaller supply - and *POOF*. Even two supplies of the same output need to be modified so they will share the load equally. The exception would be supplies designed to be ran...

    I went to take the exam for General but it was cancelled

    Good luck taking your test - I'm sure you will do fine. Do you have a phone number or email address of one of the VEs? I only have to drive about 6 miles to the test center but I always call (or radio) ahead on the morning of the test to make sure it is a go. Just a thought...

    Oxidation Removal -- Help

    X2 on the de-oxit. On some switches I'll saturate a thin strip of cotton material and slide it back and forth between the contacts. I use a solder sucker for desoldering components on (single side) PCB but for pots, switches, etc I prefer to use desolder braid.

    Best Mobile Coax

    You are correct - I misread what you were saying in regards to the location of CMC, and for that I apoligize. My post wasn't meant as any part of a "tag team" effort, I was just curious why one would alter coax length to combat CMC. I'll be the first to admit I don't know everything when it...

    Best Mobile Coax

    I use LMR-240UF for mobile installs, but that's just my preference. It's easy to route, low loss, double shield and the outer casing holds up well for years of trouble free service. I'm curious as well. If you have CMC wouldn't that indicate a tuning problem with the antenna? Wouldn't you...
