Well done! While many argue from opinion, you demonstrate. But I would like to make one point here -- that it doesn't matter whether the radio is an SDR, hybrid, or pure analog, if you remove unwanted signals before they get to the active stages, the receiver will work better. Period. So, if you are dealing with strong, unwanted signals, you should remove them in order for the receiver to perform its best. Some sort of input filtering (preselection) is advantageous. -- Brian Lloyd, WB6RQN/J79BPL 3191 Western Dr. Cameron Park, CA 95682 br...@lloyd.com +1.767.617.1365 (Dominica) +1.916.877.5067 (USA) ___ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kc.flexradio.com/ Homepage: http://www.flexradio.com/
Re: [Flexradio] 2nd request-Heros
A Google search for "longwave converter" will turn up many sites selling converters. Many of them are far less expensive than the Heroes converter and have received good reviews. 73, Ken Alexander VE3HLS On 2013-01-13 10:37 PM, Robert Costa, KB6QXM wrote: Bob, The VLF converter would probably work well with a pre-selector designed for LF/VLF.

Re: [Flexradio] 2nd request-Heros
The front end of the 5K isn't an issue if you are using a receive converter. The front end of the converter is what you have to be concerned about, specifically, it would be best if the converter had it's own low pass filter to prevent overload from local mediumwave stations. The converter output is in the 3.5 to 4 MHz or the 4 to 4.5 MHz bands...where the 5K has it's own filters. 73, Ken Alexander VE3HLS On 2013-01-13 8:49 PM, Bob Kay wrote: I too have considered their VLF converter, but after experiencing the rather broad front end of the 5K in that part of the spectrum, I'm cautiously not expecting too much.

Re: [Flexradio] 2nd request-Heros
I did promise a while back that I'd put a video up for it or at least in my case the "Heros SCR Preselector-CAT". Since I use one with a Flex-5K I can vouch that if you're using tuned antennas there really shouldn't be a need for one. If however you are using nonresonant antennas or in proximity to a transmitting station then you might be surprised at the improvements that can be had. With the greatest of respect to Tim's comment I don't consider Taiwan's Premier radio station to be very close to me in the UK however it is the station which causes me the greatest problem! Or at least it did until I got the Heros Preselector. And just to be clear, the incoming, coaxial cable has two line isolators so there is negligible RF getting back into the shack (Tested with spectrum analyser and current probe). I have just managed to put the video up tonight and it can be found at http://youtu.be/yeA8yyiK0X4 73's Nige.
