Up for sale the new 144 mhz to 28 mhz No-Tune transverter board. It has been designed and built by one of our Ukrainean radio engineers.  I tested this transverter myself and I can assure you that its performance is a very good. With this transverter you can operate on the 144-146 mhz band useing any type of your HF radio at 28 to 30 mhz or even up to 148 mhz but then you should have the HF radio that covers up to 32 mhz. Applying only 100 mWt (0.1 Watts) to this transverter on 10m band you get 10-12 W output power on  2m band. There is no antenna relay required. This sale is included the completely built and tested transverter board and the schematic diagram of the transverter and a diagram of a possible connection this transverter board to your HF radio. You have to do that connection yourself. I have made a translation of a description from Russian to English and printed the text on the back side of the sheet with an original description. There is No-Tune transverter. You should place the board onto the heatsink then to get necessary connection and it's ready to operate. This transverter so small that you can even place it inside your HF radio!

Do not apply more than 0.5 W of IF power from your transceiver to the transverter. It kills it instantly !

Below the basic information about this transverter:

  1. The DC power supply voltage is 12 V.
  2. The IF RF input power on 28mhz is about 100mWt (0.1 Watts).
  3. The Output power on 144 mhz is 10-12 W
  4. LO freq is 116 mhz and a crystal it already installed on the board.
  5. TX Output transistor is RD15HVF1
  6. RX Input transistor is BF998
  7. PTT to the ground.
  8. The size of the board is 7cm x 3.5cm
  9. This sale does not include the interface module, heatsink, power and RF connectors, wires or cables.
  10. To get the transverter worked you have to do some soldering works with a cables , wires and connectors. Probably some instruments would be required.
