222/28 MHz ASSEMBLED TRANSVERTER IN BOX. My original transverters have my website URL printed on top side of their PCB. This Assembled in Box Transverter contains the new model of Attenuator Board with RF SENSE (RF VOX) PTT SWITCH. It means you would not have to use additional PTT cable to your base HF radio. For those of you who want to have 222/28 MHz TRANSVERTER and have no time to build it yourself we just did this job for you. We got assembled and tested our known transverter KIT. It costs slightly more than just a KIT but you know time also costs something. This Assembled in Box transverter contains LATEST MODEL of our known 222/28 MHz TRANSVERTER BOARD and ATTENUATOR BOARD. If you are looking for Assembled Transverter in Box WITHOUT the Attenuator Board LOW LEVEL driving power 1… 10 mW then look at. With this transverter you can operate on 1.25 meter band using any type of HF radio that has the 10 meter band. It would work the whole 1.25 m band at 222 to 226 MHz if your base radio has 28 to 32 MHz band. It works any modes such SSB, CW or FM if its available in your radio. It is very easy to use this transverter. Just hook it up to your base HF radio antenna connector and it is ready to work! You would not need to unscrew or change the cables from other transverter. Just power ON the needed transverter and OFF the other. The OTHER BANDS TRANSVERTERS you can find. IF 28 MHz input power. 5 W 10 W max. (Doubled freq of 97.000 MHz Oscillator). LO frequency stability. Output power on 222 MHz. Contact closure to ground or RF SENSE (RF VOX). +13.8 V DC +12… 1.3 A (TX). TX Output transistor. RX Input transistor.
