EasyPal works well with PowerSDR .

Just be sure to confirm the soundcard setup each time you start EasyPal.

Heard some guys using digital SSTV on 20 meters and got curious since I had
done some SSTV about 15 years ago. They suggested I give it a try. Anyone
using EasyPal software with PwrSDR? Any suggestions on configuring the
software. I have DDUtil installed, VAC.

[Flexradio] FlexControl dead

[Clyde Washburn]

I have two FlexControls, one on a 5000, and one on a 3000.  The one on the 3000 
has suddenly gone dead.  Although the lights come on
when you plug it in, and it gets a COM port, neither 2.1.5 nor 2.2.2 react to 
it now, nor will it work through DDutil.  The lights
no longer come on when FlexSDR is started BTW.  It's only a week or so old - is 
this a warranty failure, or have I missed something.

[Flexradio] USB External Keypad Dedicated to Flex VFO

[W6SDM Steve]

I am going to submit this as a feature request, but I also wanted to see if
anyone else thinks it may be viable in the way that they operate,
particularly in contests or DX.



I use a USB external number keypad.  I keep it in close proximity to my CW
paddle and Flex Control.  Provided that I have focus on PowerSDR, all I have
to do is key in a frequency and hit enter to go immediately to that
frequency.  While one of my spotting software programs will tune to the DX
frequency through CAT control, I may sometimes use more than one cluster.  Or
I may want to just go to a particular frequency for one reason or another.



Of course, the problem is that you must have Windows focused on Flex in
order for the keypad to work.  Worst case is that I end up typing numbers
into something that I don’t intend to like my logging or spotting software.



So, what if the keypad could be dedicated to address the Flex VFO regardless
of focus?  Much like the Flex Control does on vernier tuning, the keypad
could do on direct entry tuning.  External keypads are cheap and readily
available



I have no idea what kind of programming or driver it would take – hopefully
someone a lot more adept at these things than I am can figure that out.



Is this a sensible feature request or have I had too much RF exposure?

Re: [Flexradio] RX2 Protection during transmit

[n3wt]

Per the Flex specs on the 5000:   "Full duplex without the need for a second 
receiver installed for the ultamate CW rig"

How does one set up full duplex without the RX2?  I assume separate 
antenna and then settings on the antenna routing options??  Will this really 
work without RX2?   

Curious.

Subject: Re: [Flexradio] RX2 Protection during transmit

Jerry is correct on all points.  The FLEX-5000 has a stout front end and 
it will take a signal in excess of 0 dBm to saturate the ADCs.

You should be OK unless the RX antenna is in the near field of the 
transmitting antenna and you are running very high power.  My antennas 
are in the near field of each other (5' separation) and I have no issues 
at 100 watts other than pegging the S meter on the RX2 :-)

If you are worried about it, then there are some devices that will 
switch out the RX antenna when transmitting from companies like DX 
Engineering and Heros just to name two.
