I am looking to buy Ranger RHF-618 10TO 12 METER CB

some Rangers you can go to their site and get the information.I would google it then search for what I need then use that information.

FOR ALL YOU MISS GUIDED FOLKS CONNEX IS NOT PART OF COBRA IN ANY WAY SHAPE OF FORM PERIOD ...CONNEX IS MADE BY RANGER U S A . AS FAR AS THE RECEIVE IT IS PROBABLY ARE MISSED SWITCH OR CONTROL NOT SET RIGHT SIR

I HAVE THE SAME PROB WITH ALL THE STATIC , %50 OF THE MEETER MOST OF THE TIME, HARD TO HERE EVEN LOAD STATIONS, CAN ANY ONE EXPLAIN , IT IS ONLY ON THE 618 , NOT MY PRESIDENT ,,

Check RF transistor may have leakage, "probably won't show up on a regular meter, carefully inspect board for bad solder connections, buy semiconductor cold spray may help tracking faulty part.

you cut the wires trim off some plastic and attach a spst switch on both wires.

CB............... citizen band is 11 meter.

That is an 11 meter with Single Side Band radio.

buy some mr.freeze and spray some in the pll area to see if it drifts back on frequency. once you have determined that take it to a tech and let him know what you did and he will fix it.

schematics and alignment procedures are widely available for this radio on the internet. a little research goes a long way.

p.s. if you don't know what you are doing leave it for a skilled tech. you could cause some major issues if you "allign" the wrong thing.
