More trimming, PSUs moved, PC replaced, 7400 & and FDM-Duo out, and becoming nearer 100% Icom

 

Antenna for 20-17-15-12-10 is just a cobweb about 15' off the ground

Recent changes to WO-PSK

My PSK-31 programme (based on the work of WA0TTN and AE4JY) has remained mostly unchanged sinced 2001. I have added and taken out control for various makes of rigs as I have bought and sold them (Presently supports Icom, Yaesu FT-950/450, FT817, FT847 and Flex (1500)).

I have recently added more bands, changed the volume control links to work on Windows 7 (will not open the volume control on XP now, that would have to be done through Windows).

The most interesting change to me though a week ago (June 8) was to add filter control for the Flex.

The software will now read the frequency of the signal you are decoding, and set the filter to a narrow bandwith around that signal, so the problem of a very strong signal on another part of the spectrum is mostly eliminated. It also helps with the recovery of a weak signal.

 

Narrow selected around the wanted signal. Notice the Flex filter settings, variable filter selected and the low and high settings set to either side of the signal frequency.

Back to 2.7k to look at the whole width

 

You don't need the Flex software to be visible, all is controlled by the WO-PSK software.

 

If you have a very strong signal close to the wanted signal, you can move away from it, set the filter so that the wanted signal will be just inside the narrow filter width, then select the wanted signal again, and as the filters on the Flex are so sharp, it will eliminate the unwanted signal unless it is extremely close to the wanted signal.

 

 

 

QSLs

I do not normally send QSL cards, however I do respond to every one I receive. This is the only time I send cards. Thanks

 

Single feed 2m/70cm and single feed 6m/4m antennas.

G3EJS was my late father's call sign. I applied for it when I returned from SA.
