[hpsdr] [Bulk] Re: Fwd: PSDR 3.3.7, TX problem Pure Signal

[Scott Traurig]

George,

I have noticed some odd behavior when using diversity. This is on a 100D.
Many times in order to get it to start working I have to first sync the
VFOs and turn on RX2 manually. Then I turn off RX2, open the diversity
control panel and turn diversity on. At that point it should be very easy
to see if it is working by using the buttons in the diversity control panel
to switch between RX1, RX2 and RX1+RX2. As you know from using diversity
with your 100D, you should clearly see the difference in the spectrum
between RX1 and RX2.

73,

Scott/w-u-2-o

Previously I ran the MFJ box and used a TH11 as the secondary antenna, and had super results..But on the Anan 200D all I basely get t is the ability to play with amplitudes and never can find that sweet spot for noise elimination..Not sure if tis question should be directed to Anan or HPSDR>
