RF gain makes a good squelch

Post by Turbo-T » Friday, 24 July 2009, 22:12 PM

So it seems the squelch does an ok job of filtering out static, etc....but an RF gain works great for when you don't want to listen to staticy Jim's convo that you can barely make out 35 miles away. Who agrees here?

Well, I have seen many-a-folk use the RF gain and squelch incorrectly. This usually leads to "I can't hear you", or "why can't I hear x miles". The squelch is used to blank the white noise and it shouldn't be turned up any higher than necessary to "quiet" the receiver. The RF gain can be used to turn down the amount of signal which is coming into the receiver. Using them both is where some set them incorrectly. Once you adjust the RF gain to where you want it, THEN raise the squelch level until the receiver quietens. I have seen some folks turn the gain down without ever re-adjusting the squelch and many times it will take a very strong signal to "break-in" once that is done. Especially when they have the squelch turned full CW.

I guess I'm weird, squelch or reduced RF gain makes me feel like I may miss something. I rarely use the squelch and could do without it altogether. The ONLY time i use it is maybe once a year, car to car, with family on a trip, and that's a rare deal. I like to hear it all, including the static. It is funny you mention RF gain as a squelch replacement. I have a radio, an hf one, that lets you choose on a menu, for one particular knob, whether it is a squelch or and rf gain.

Ok I'll use this example.

I'm on the interstate and all the truck drivers are on 19, some of them are 3 miles down the road, their transmissions are somewhat audible but have a lot of static in the convo. But then I have a few truckers maybe a mile in front of me.

I set up the RF gain to 1/2, then the only people that get thru are the ones a mile away and their transmissions are audible, no static, clear as a whistle.

Heck set it all the way ccw and then ONLY those a mile out get thru.

Yeah I know this isn't exactly what the RF gain is for but it does work when you don't want to hear what's on 3 miles down the road w/all the static.

Also because there's so much white noise that the needle on the RX meter is hitting the red. When the RF gain is cut back it drops down to 1-2 S units, which is where I wished it would stay. I just know it limits what's going on waaayyyy out there, but just what you have to go thru today I guess.

Heck I heard that once upon a time unless someone was talking away the needle usually stayed at 1-3 S units. But due to no advancement of the CB radio and all the devices that induce interference have caused issues.

Or, get you one of these and leave the squelch and RF wide open. That particular model isn't made anymore but Heil took then in and makes a comparable speaker at an even higher price. I've had my AmCom for several years now and matched with my new Stryker 490(with its great receive) makes for a great mobile rig.

I dont mine a little static every now and then and i will be the first to admit that when i run up and down the highway i have the squelch and rf gain wide open. I dont however like it when the static stays bout 1-3 s units not up in the red. I am in the process of right now figuring out how i can keep the static down on my general lee and after grounding everything i still got no idea i am thinking its prolly something with my coax
watchdawg just got down now im 10-10 on the side
