I have a Uniden Grant XL, I was told it was pretty much untouched. I'm sure it has a multiple-turn pot in the clarifier... Is there a place I can look at the scematics and potential mods that might have been done to this radio...I plan on taking it to DTB to have it aligned, just wanted to...

I think the answer to my problem is lack of chassis grounds... I have static in my receive, a lot of it, as in around 7 S-units. I figured it was from a cellphone charger and XM receiver (unplug either one and it subsided). However, I can also simply place my hand on the radio and the noise...

I just got a Galaxy DX 959, one of its features is a "GNF" or Galaxy Noise Filter which is supposed to reduce the "rushing noise." I've been running it a little, and while it does help quiet things down, over half of the RX transmissions are distorted (like they are seriously over...

I just picked up a DX 959, had it aligned and tuned. My first SSB radio. The Galaxy manual is lacking much detail in SSB operation. A lot of these manufacturers need to take a course in technical writing...and provide better manuals for their junk. As I understand it, its as simple as...

A friend has a no-name 4-pill in a bright blue case...Class AB, 4x1446s...has a printed circuit board. Hooked up to a Uniden 78, running mini-8 coax into a roof-mounted Wilson 1000. When he flips the amp on (just turns it on) the RX signal drops and sometimes slowly builds back up (like...

What's the difference between a AVG watt and a PEP watt? Does one or the other actually represent the watts staying on frequency?

Just to satisfy my own curiosity, what does the SSB switch (on an amplifier) actually do? Does it have any affect on an AM transmission (say the switch accidentally gets flipped and you're still running AM, not SSB)?

What are the input drives for the common pills like the 1446, 2290, and 2879?? How do you figure the input requirements of multiple pill amps with these pills? Do you multiply the input drive of the pill by the number of pills?

I was doing some reading on this forum regarding the 102" whip, and someone made mention that MJF/MFJ (not sure which it is now) makes a solid whip, as opposed to a "hollow" whip. The hollow/solid reference was in context to the amount of flex the antenna has. I'm assuming it has to do more...
