My 222 MHz transverter was designed and sold by Serge Zhovtobrukh (UT5JCW) from Ukraine (Transverters-Store.com). It is a second generation design with a temperature compensated crystal oscillator (LO stability +/- 1 ppm) and additional local oscillator filtering (compared to his initial product). The transverter has an output power of approximately 10 watts for an input power of 10 dBm (10 mw). This transverter is interfaced to my Flex-6700 via the Flex-6700 transverter port. The transverter has an IF range of 28 MHz to 32 MHz but the 6700 displays the 1.25 meter frequency directly (222 MHz to 226 MHz). The transverter is powered by my 13.8 volt, 35 amp Astron power supply.
