While playing with PSK31 this weekend I have noticed that every so often I
see huge frequency shifts in the "waterfall" and when I turn the volume up
on my radio I can hear the tones shifting. So to the Question: Are the
frequency shifts normal or should I start looking into issues with power,
antenna, or heaven forbid radio?
My current configuration:
Radio / Antenna:
Huslter 6BTV (just recently moved to a new spot in the yard this past
Wednesday) is connected to a feed through by a 100Ft piece of Low Loss 400
from JefaTech.
>From the feed through to the radio is another 50ft piece of Low Loss 400
from JefaTech.
For power I have two supplies 1st is an MFJ 15A cont. 17A surge that I had
bought for the FT-8800R but works great for the FT-890 in QRP'ish power
settings.
I also acquired a power supply rated at 20 watts cont. and 25 surge from the
Club meeting in June. Both seem to be working while I have had the meters
connected.
The Radio itself is the FT-890 with the Auto Tuner installed.
Computer:
Dell Latitude D830 connected to the FT-890 via
1) CAT cable (USB to 6 pin mini-din)
2) Home brew audio cable that takes the audio from the data port on the
radio to the sound card in the laptop.
Running Windows 7 Pro with HRD 5.
