Ken Sco Cares

Thought I would write you and tell you about one of your advertisers, Kensco Comm. of Gumcy, Mass. J had bought 2 sets of xtals from them and used them on my mobile and home 2 meter rig Then the guys who own one of the local repeaters, because of some 3rd order inter mod, decided to change frequency. I figured I was out S20 for the 4 xtals, having none for the new frequency. So I write to Kensco and they came back with a very interesting policy If you bought xtals from them,, you can exchange...

Fs Field Strength Meter

The FS 20 Field Strength Meter is a wide bandwidth, extremely high sensitivity, digital reaifout rf power monitor. This instrument is highly suited for monitoring the output power performance of communication transmitters over an extremely wide fre quency range without connection to the transmitter. All two-way radio users want the confidence of knowing their transmissions are getting out. The field strength meter approach to accomplishing this is especially valid since the radiated powei from...

Rewards to the experimenter could be great, and the right answers could change our whole way of life. In the recent mad dash of space age research we learned how to ask more questions than we are able to answer. New developments in instrumentation and methods of observation have shown us that a lot of things are happening that we just can't explain. With the recent decline in research money for the big labs, and most of all, with u Itraconservatism increasing in established science, many of...
