Getting lots of e-mail: "Test the I/Q, test the I/Q!"
So far, have tried two different pieces of software
and a cable that I made myself...
and I see lots of neat spectrum on the display
but the audio is rubbish - pops, bops and squeaks...
Very likely something that I am doing or not doing.

OK - here is the challenge:
I have the DX-R8T receiver. And yup, it has I/Q o/p
on the back...
and I have tried it with one piece of SDR software (KG-SDR)
and the result was a very dis
Hi Guy,
I don't have an DX-R8 receiver therefore I cannot comment on how the I/Q
output was implemented. Strictly speaking, and based on Alinco's ad, the
DX-R8 would qualify as an SDR front-end. Once the I/Q is fed into the
computer, all settings are controlled by whatever SDR software is used

Howdy Rick,
It's great to see this entry to the dwindling world of tabletop
communications receivers. However, by no stretch of the imagination could
this be called even a "part SDR" radio.
You're right Guy. After looking again it does seem to be fairly

Yes, you're correct. The narrow SSB filter can be used in the AM mode.
That's not new. You can roll the IF shift as well in AM to improve the
audio. It's a good utilities radio, as one would expect given it's
transceiver heritage. It just didn't do much for me as far as broadcast
listening. I f

Actually -- the DX-R8T th
It does have about 10db attenuation in the MW band. However, the 10db
preamp also works there. I found it to be pretty decent on MW in SSB.
The sole AM bandwidth is around 9kHz, and lacking in rejection and
slopes. The front end was decent as well.

Being a small radio I guess R-390A would take up too much space on the face
plate. Seriously, being part SDR and part traditional receiver makes it an
interesting combination. Just how good it is on MW is the question. From
the specs it looks like it may have attenuation in the MW bandpass filte

The name alone makes me think that
Alinco is a tad on the bold side...
I mean, who in their right mind would
dare to take "R8" and slap it on a radio
unless they knew they could deal with the
