If Frequency

Post by larrykingair » Sat May 16, 2015 8:46 pm

For HF up conversion, 40, 100, and 125 MHz are used. In addition to moving the HF spectrum to a relative quiet space, are there any other benefits of one up converter frequency over another?

No other real benefits that I can think of. I think the best ones use frequencies about 100 MHz to avoid the FM broadcast band.

Isn't 100Mhz in the middle of FM band? (88-108)

SV1AFN upconverter has 200Mhz IF, it includes LN amplifier and covers DC-55Mhz; it's more expensive than Ham it Up but for EU buyers there is no custom clearance

Oops, I meant to write above 100 MHz, not about.

I think the SV1AFN is definitely a good deal.

I know like Makis' other products. I will probably get one of his 200 MHz up converters.
