[hpsdr] Please more info on reusing an analog rig for HPSDR

[Ben Witvliet]

Hello Joe, K5SO,

 

I read your message on the re-use of your IC-7800 for HPSDR with a real
Eureka feeling! 

Can you give us more advice on that? 

Any suggestions on what I'll have to do to break-in on my FT-990 to make it
an HPSDR-990?

 

I have 'First Light' on my HPSDR (Atlas, Ozy, Mercury, Penelope). But I can
hardly wait to start experimenting with Whisper, Olivia and Coherent CW with
it. Also read a lot about signal recognition with second order statistics.
This digital receiver thing really is exciting.

 

So the sooner I can get this little box of miracles seaworthy, the better!

And this might be a real fine shortcut without sacrificing quality.

Dwayne,

 

To chime in too, I also use the OpenHPSDR rig (Ozy, Mercury, Excalibur,
Penelope, Atlas) as my primary radio at full legal power on the HF bands
with external amps, and full legal power at 432 MHz and

1296 MHz EME with it as well (with external LNAs, amps, sequencers, etc).
The performance is absolutely astounding!  The rig replaces my IC-7800
because it simply outperforms it, hands down!

 

I use the HF amp section and T/R switching section of the IC-7800 to provide
up to 200W output to drive an external linear amp to 1.5KW and using the
pass band filters on the IC-7800 there's no need for an Alex filter board at
all.  The 0.5w rf output from Penelope is more than enough to get full legal
power in that way.  I've helped a friend configure a similar arrangement
with his OpenHPSDR rig using an old Kenwood transceiver as the power amp,
T/R switching, and band pass filtering, too.  It's very straightforward to
do without mangling the original transceiver in the event you desire to
restore the transceiver to its original configuration later.

 

A major advantage of the OpenHPSDR approach is that you can literally make
it do almost anything you wish by modifying the software yourself to do so
if you don't mind experimenting with programming.  That's especially true
now that KISS Konsole software is available; it's a simpler program than the
complex but highly successful PowerSDR program.  KK is aimed at the novice
programmer to allow him to get his feet wet trying out his own ideas without
being overwhelmed by the complexity of PowerSDR.

 

I'll never go back to analog transceivers, that's for sure.  OpenHPSDR units
certainly are not a plug and play items but if you're willing to get your
feet wet learning something new and have some initiative to do so it's well
worth doing it in my opinion!

 

Good luck!
