Ere it comes folks, another CB rig converted to ten meters the Johnson Viking 352 This rig has a great deal of flexibility when properly modified. It can offer more features than the average CB-to ten-meter conversion, and this means more QRP contacts for you. The 152 is an SSB AM eleven-meter 23-channel transceiver. The logical place to convert it seems to be 28 5 MHz to 28 8 used at the lower end and the AM section will cover the upper end where there is activity in this mode. At this point,...

New Uhf Transmitting Converter From Hamtronics

Hamtronlcs, Inc., has done it again In the tradition of other fine products, they have a new UHF transmitting converter, and just in 'me to gear up for the new OSCAR Phase III. Oe signed to convert 28-30 MHz to 435-437 MHz or 432-434 MHz, the new model SV4 requires 1 mW to V2 W of drive to give 1 W PEP output on SSB or up to 1 M2 W on OW or FM. If you have one of the older 10m exciters which doesn1t have a low power trans-verter output, don't worry, because instructions with the XV4 tell you...
