Here in Southern Oregon the skip has been short skip, lots of S.Cal, Idaho, Montana and Canada. Haven't heard any from the East Coast lately.

I haven't heard much skip from the East lately, most of the skip is from SoCal, Arizona, New Mexico and the Canadians. Last evening I talked with a guy from Australia. I used a Kenwood TS-430S with a Sigma Venom 1/2 wave antenna.

Have you check Q19 & Q20 on the RF board? Q20 is the per-driver. The RF signal is sent to the Final PA deck via Q19 & Q20 via the T/R relay into the Filter Board. The Filter Board has a number of relays and depending on the band you have selected will depend on which relay is active.

The propagation pattern of your proposed antenna would be effected, it would be a carotid pattern ( heart shaped) with the "null" in the direction lacking the ground radial. If this null was toward the roof and your roof was metal, then you could run a braided ground strap from the missing...

Seeing how most 1/4 wave vertical antenna have an input impedance of about 42 ohms you'll never get a 1:1 match. A match of 1:2 to 1:4 is as best as your going to get.

Your power loss @ 2db for 200 feet of RG-213 will be about 1.75 watts, the gain of your antenna should make up for this loss.

I worked for a major communications company for many years, we were required to wear RF monitoring devices when we went to a site. RF can and is harmful to any living tissue if it is overexposed. The higher the frequency the more pronounced and quicker the damage can occure even at relative low...

Noise in a radio is a common problem due to the band CBs operate in, the lower you go in frequency the more noise you receive. Your problem maybe coming in through the antenna or simply coming in through the receiver frontend. These can be over come by crystal filters but that can get expensive...

You really don't need to worry about the line loss unless your are running your line a couple hundred feet. Line loss for RG-58 isn't that much at 10 or 20 feet. Seeing how coax line is an unbalanced line the lenght isn't that important if it is terminated correctly. If you are using coax line...
