If Cat 5 cable will work why won't two wire twisted air audio cable? Is it because of the tightness of the twist that is of concern. I see no reason it won't work except for the cancellation property of twisted pair but with a Beverage we are dealing with a different wire signal propagation

Lee you might check the AM band and see if there is a detectable carrier on 603.6 or 905 Khz as sometimes unlicensed AM pirate stations try to slip in between the noram AM 10 KHz increments to avid interference. I could be one such station's second or third harmonic with the carrier just left

The majority of sailboat and powerboat cruising crowd (some call them yachtsmen) are to busy when they are at the helm to do internet. However when they pull into a port or harbor and drop the anchor and pour two fingers of Dewer's White Lable it is then they wish to catch up with their stock

Mike, The issue with cruisers using the ham bands is that so many are not even legally licensed or if they are have no permit to operate in the ports and harbors where they are visiting. Most of the islands in the Eastern Caribbean do not permit third party traffic of any kind. So the

Bruce, I can't answer your wind turbine noise question on TB but while we are on the subject and a bit off topicin the 70's a 250KW wind turbine with metal blades was installed on the island of Culebra midway between Puerto Rico and St. Thomas. As the blades were rotating they would

Is there not a built in loss of 3db on both TX and RX with a CP antenna compared to an Axial mode antenna? Not that it makes that much difference on RX but 3db is 3db. Another issue with CP I understand is the difference between LHCP and RHCP for space communications is supposed to be
