Re: Perseus Preamp

The Perseus preamp is not a conventional preamp - this article is interesting http://play.fallows.ca/wp/radio/software-defined-radio/perseus-sdr-preamp-mystery-is-solved/ I always keep the pa on to optimise snr and then use the attenuation to eliminate clipping. In urban locations I have found that ...

Re: TGN Technology UNLA 3018

I have a TGN ULNA 3018 Mk.IV Band 2 masthead preamp in Carcassonne which works well. The UK's premier Band II dxer Mike Fallon uses one with his 19 element Korner.

If you do the Konrad modification with the add-on Seeeduino board and turn on the unit without the usb connection to a computer the radio will just hang flashing "wait". Assuming there is no add-on Seeduino board then you need to look in side t...

Re: For a better FM DXing, a Yagi or a vertical aerial?

Tropo maintains the polarization of the transmitted signal. Sporadic E doesn't.

"the overall performance of a yagi antenna much greater than a vertical one?"

If the Yagi is pointing in the direction of the transmitted signal of course. If it isn't - probably not.

Re: Unid Scottish on 52.875

At the beginning it sounds like Clloyd Community Radio Station.

The Clloyd is almost certainly not correct - may be a gaelic name. Can't find anything similar on ofcom's list.
