Thanks. I created an aggregator folder/program copy for each skimmer
occurrence, and have 40m and 80m both up and running.
Appreciate the advice about the I/Q Balance calibration. That explains
some of what I have been seeing when trying to calibrate the frequencies.
On the transformer issue, I've been searching for a less expensive
solution than the iso xfmrs rated for wider bandwidths(Triad, et.al.).
It appears that the Radio Shack part is no longer listed. So far, the
inputs straight out of the Softrocks has not been terrible, but there is
definitely a large spur on the center frequency. I have the Softrocks
isolated from the antennas with transformers, and a bit of extra
filtering/bypass on the DC line as well.
The antenna situation is the next project, as well as some front end
xmit and lightning protection. So its going to be a 'fair weather'
skimmer station fo the immediate future. This is all on a shoestring
budget, so improvisation is required.
73 es tnx fer all
