I'm wanting to calibrate the modulation meter on a DX979 but I don't have an O-scope. My theory is that if I arbitrarily set the MAX OUTPUT (100% Mod) @ 30W, and run my signal generator through the mic @ 200-250 Hrz (for the tone of my voice), that then I'll be able to adjust the meter for 100%...

Is there a replacement for the 2 digit display on the DX979 that can change from red and blue? I love the intense blue during the day, but it is oppressively bright at night in the mobile, even with the dimmer turned down.

Just noticed That one of my neighbors must have found a new way to make money during this new period of "Economic Growth" that I keep hearing about, because my radio now has around 4 S-units of noise for at least (as far as I can tell) well over 12 hours a day. My typical is usually less than...

When I put a 1K tone into the mike on sideband, my frequency counter reads 1K Hertz lower on LSB and 1K Hertz higher on USB. i.e. 27.3840 LSB, 27.3850 AM (no tone), 27.3860 USB. Is this normal?

I am running a Radio Shack 64" ss whip antenna on my SUV and I've heard that if you use a pot-belly spring on it, that the SWR's will improve. RadioShack Stainless Steel Mobile CB Antenna : CB Radio Antennas | RadioShack.com I've tested it with and without the PB spring and did notice...

Forgive my repetition in this question: I know just enough about electronics to get myself into trouble, and especially the stuff concerning capacitance and impedance. And I want to understand, in a very rudimentary sense, how impedance effects the signal traveling through the coax and...

I was wondering if anyone has used or built a Magnetic Loop Antenna for 11 meter base station? I looking for an alternative to my stealthy 102" whip that works pretty well concerning its limitations. I've seen on the Y-tube that an operator made one with only 6 feet of 3/8 copper tubing...

Has anyone ever heard of the Uniden Pro522xl ssb?:tongue_smilie:
