Google of course, but it seems getting worse and worse...

IF you have an HF transceiver there are VHF transverters available from both
Ten-Tec and Elecraft

Fine, but notice, please from where I am writing ( .pl is for Poland).
The costs of shipping, a local tax and zoll payments will rise price
about 75%. That's first notice. The second one is I want to build it
myself. That's why I choose homebrewing group.
