[Flexradio] (no subject)

2009-12-21 Thread David Cole
Can anyone help with this observation - firstly I have had two Flex 5000A - 
after selling the first I missed the 5k so much that I bought another. Ok onto 
the observation. My interest is 80m DX which involves attempting to receive 
very weak signals (SSB) . A friend has lent me a K3 to try out for a month or 
so and I have given it a good testing over the past two weeks - and in every 
comparison the recovered audio on weak signals is far superior to the 5k - I 
have tried playing with the equalizer but I cannot get it any where near the K3 
- on the K3 the week signals are clear and easy to read, on the other hand the 
5K is to mellow and rounded - its not sharp enough. Has anbody tried this and 
are there any fixes that I can do to bring the recovered audio on the  5K up to 
the K3. Sensitivity wise I would say they are the same, many thanks and Happy 
Holidays to all from Dave.

[Flexradio] Remote operating

2007-12-03 Thread David Cole
Hi all - I wish to select my beverages and other relay operated items from my 
remote location - has anyone written a program similar to the SDR 1K where a 
matrix is selected and the output is directed to the RS 232 port or possible 
the parallell port - to switch a transistor and subsequently a relay.. Many 
thanks de Dave G3RCQ

[Flexradio] 160 preamp

2007-11-03 Thread David Cole
160 Receive Pre-amp - I wish to have the option to switch the receive pre-amp 
on on 160 at the moment this is grayed out.

There is a big difference in receiving low signals if the pre-amp is enabled.

The noise floor using 250mtr beverages is -100dbm 2.001khz without the pre-amp. 
With the pre-amp enabled this drops to -112dbm.

Very low signals which are totaly unreadable become Q5 and workable - I have 
made the same tests on 80m and the results are the same.

Has anyone else experienced this situation? if so is there a fix? how easy is 
it to change the software? - Dudley I have also emailed you directly on this 
ongoing problem. G3RCQ
