ES 144 MHz

Tuesday DAC 144
ES IS0OZK
20190702 1858 144299.9 USB  PA0O          57  IS0OZK           57         jm49MH   
This was my first 144MHz ES contact with the K3 + XVTR  and the 200W PA build this year https://youtu.be/I0unVRHhJEA     including IMD splatter hard to copy

But a very strong local contest DAC station blocked my receiver total!  Splatter all over 144-146... Then i took the heavy old FT221 from the shelf and this receiver almost no splatter.. with its original frontend no Mutek modification So the transverter using simple D-gate mosfet mixers is suffering IMD to much  A pity this well build XVTR was not designed with hi-level mixers and TCXO  Very low prized only 30$ complete build and ready to work. Ik hope Transverter shop will offer an improved model in future a higher prize will be justified. with modern hi-level / low IMD setup and TCXO
