|    Conversion up or down?    |

      In a message on Friday 09-01-16 Richard Menedetter said to Holger       Granholm:              Good day Richard,              RM> An Upconverter is needed to convert a lower frequency signal to a       RM> higher frequency signal.              OTOH, a downconverter is needed if I want to use my FT-290 VHF (144 MHz)       transceiver to send on the HF (SW) bands. That is what my 'Tokyo HI-Power       VHF>>HF Transverter' does.              IOW, converting the 144 MHz signal to for example 14 MHz.              RM> See also the descritpion for the Ham-it-up upconverter:              RM> It seems that the convention is the other way around.              You are actually converting down the receiving frequency band to be able       to receive frequencies below the 25-1300 MHz band, that the thumb-stick       is designed to receive.              Yes it seems that the Ham-it-up that you are referring to, has got the       convention on the back foot.              In all my life as a HF-VHF-UHF-SHF ham, I have built converters to be       able to receive VUSHF, on for ex. 28 MHz.              That is downconverting, ie. converting the 144 MHz signals to 28 MHz.              When I wanted to use my Drake TR-4 transceiver to transmit on 144 MHz,       I needed an upconverter.              So, finally it all depends upon from which viewpoint you look at it.                     Regards,              Holger              ---        þ MR/2 2.30 þ And on the 8th day God said, "OK Murphy, you take over"        * Origin: Coming to you from the Sunny Aland Islands.
