OK Ed, I am sure Ten Tec will work with you on the noise floor problem. It may be only a badly crimped jumper cable, or as I stated either a loose screw ground or bad solder joint. My Scout is very q
Loop back testing for standard RS 232 on a 25 pin connector is as follows: Transmit to Receive, pins 2 to 3; then connect pins 4&5; and another jumper among 3 pins: 6,8,20. Since you are looping back
It would be better to do an ESR test on the electrolytics before replacing some that might still be good. On direct conversion receivers, some care is needed to avoid picking up hum from a power supp
Misplaced the 259B manual. I know we will find it after asking this question. The 259B has a time out function, to save the batteries. Is there a way to defeat that automatic shutdown? Like if you ar
Probably not possible with older IF and mixing schemes. It will take a case by case basis as to whether it would work without excess birdies. 73, Stuart K5KVH
The simplest method to use one speaker with multiple audio sources, is a resistive mixer. The formula is in the handbooks, like "SAMS Handbook of Electronic Tables and Formulas" as well as many other
Hobby shops should have sources of plastic which a good woodworker or metal craftsman can use to fabricate a copy of the broken part(s). Ask around your ham club for craftsmen, or put a note up for h
Sorry, just gotta tell this story. I feed birds, and have a large number of large white wing doves who have learned to be hanging feeder users rather than ground feeders as normal. One day one was aw
First before sending radio off do two simple checks: Reseat all cards and connectors, and check power supply voltages. Might save you a lot of time if it is only bad connections or simple power fix.
Those who have had good results with ground mounted radials may be in good earth areas. We who have almost no earth to call RF ground, have found elevated ground planes and radials very effective. Re
The proper technique with any shape mike is to speak Across the element, rather than directly into it for maximum shortwave radio intelligibility. Although the Heil Classic looks like a differing mik
I think this is their Pi Net transmatch, and it does a great job. The one we used at Field Day of course was single ended output being a Pi, but we just hung a Van Gorden 4:1 balun on its output and
I do not think it will make the components last longer, in fact, the failure of the electrolytics is a drying out action which is only hastened by the hours the supply is on and producing heat by edd
Try your local Wal Mart fabrics section, or any good sewing goods chain store selling material (cloth) they all sell vinyl now as well for upholstery projects. 73, Stuart K5KVH
Carl and the group, When the Scout was designed, there were 3 terminal regulators that required a larger differential of voltage to regulate stability, than the low drop out regulators that came late
