Mobile CW Operation

Ham radio's oldest mode keeps rolling Wait a minute, whafs that again Who would want 10 operate mobile CW I do. for one. and I'm finding a growing number of mobile CW enthusiasts on the iF bands who must agree with me that it's great fun and more productive than mobile phone (SSB) operating. CW is our oldest mode of amateur radio communications, and enjoys an 80-pIus-year history of hundreds of thousands of operators and many millions of successful contacts made. Yes, it's old-fashioned, but CW...

The Sr Connects To Any Transceiver To Make A Simplex Repeater

* Portable or mobile repeater to increase the range of HTs * Emergency repeater Test repeater to hear your own signal * Test for skip conditions Unmanned hidden transmitter * Calling frequency machine The 7110 has two modes of operation. In the automatic mode the repeater only repeates when there is no reply to a transmission within two seconds. In the continuous mode all transmissions are repeated without delay. The 7110PL has a PL decoder so the frequency can be used without the repeater.

Cjv

Schematic for the converter Ql, also an FET, is a source injection mixer It produces both the sum and difference of the input signal and he 20 MHz local oscillator. The output circuit, consisting of the larger winding of T2 and capacitor C3, is broadly tuned to the sum frequency range. We don't really want any selectivity from this circuit since we have plenty of selectivity in the 10 meter receiver connected to it. The circuit operates from 12 volts, it would probably operate just as...

Stacking UHF Antennas

Venturing into amateur television or ATV for the first lime presented me with new and exciting challenges. Not only was I operating at unfamiliar frequencies 1 also had to deal with the greater bandwidth needed lor video transmission. The most important consideration for me was the antenna system. Towers and large obtrusive antennas are not allowed in my subdivision. Next to a good antenna system, overall height is the most important factor For my application, height was not a problem since I...
