[Skimmertalk] comparison

Sun Aug 23 06:36:22 PDT 2009

At least for a while I am running two skimmers off the same antenna to allow
comparison of decoding.  Both of them are feeding spots to the reverse
beacon network now.  I will keep them running as much as I can, but won't
guarantee availability of both.  The equipment/software is:

K1TTT: QS1R and skimmer server v0.94 (available at k1ttt.net port 7300)
monitoring 48khz starting at 1800, 3500, 7000, 14000, 21000, 28000,

K1TTT-1: SDR-IQ and cw skimmer 1.4 (maybe available at k1ttt.net port 7301
please let me know if this works) set for 96khz sample rate, using wd5eae
scheduler to rotate between 1825, 3525, 7025, 14025, 21025, 28025khz
depending on time of day.

Both are on a 25-30' vertical.  Both are set to minimal validation.

On my first quick look it seems that the sdr-iq is more sensitive and
generates more spots.  Though sometimes the qs1r gives better snr values.
