144/28 MHz Transverter Board
 


To note please: 

My original transverters have my website URL printed on top side of their PCB. There are a lot of fake transverters available on eBay .

=========================================================

Up for sale 144/28 MHz or 2/10 meters band transverter board.

We designed and built this transverter board with a purpose to bring an affordable low cost and high performance Transverter on the Ham Radio market. Over the years we sold a lot of them. Just to check my feedbacks!


With this transverter board you can work on 2 meter band using any type of HF radio that has 10 meter band. It would work the whole 2m band at 144 to 148 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.

This NEW model of 144 MHz Transverter board allows you additionally use separate RX/TX outputs of your base 28 MHz radio.

 
What can you do with this transverter board ?
 
 Make your HF radio works on 2 meters band.
 Convert your Flex Radio or other SDR Radio into all mode 2 meters transceiver with a Spectrum Waterfall.
 Use this board as the RX converter with SDR or HF receiver and get 2 meters band there.

We are offering completely built and tested in our lab board that comes with the English description which contains the circuit diagram of this transverter and circuit of a simple attenuator board.

If you're going to connect this transverter board to the radio that has 100 W output power the some sort of attenuator between your radio and this transverter board is necessary. We designed a simple attenuator board which contains a few resistors and couple relays only. You can easily build it yourself.

Or you can buy the built and tested ATTENUATOR BOARD there

In case you were going to connect this transverter board to the FLEX Radio then NO attenuator board is required.

In respect and to the favour of our buyers we put the TRANSVERTER BOARD and ATTENUATOR BOARD together in a ONE SALE as just the boards or as the KIT with a BOX and other parts.

To buy the 144 MHZ TRANSVERTER + ATTENUATOR BOARDS together there

This sale is not including the attenuator board, heatsink, power and RF connectors, wires or cables. You are getting what you see on the pics.


Also we are offering the ASSEMBLED TRANSVERTER IN BOX or the KIT.
