You can also use the MAC SCSI cables. I Got one for 6.00, cut it in half for 2 cables.

If you don't have have a keyboard to rip apart you could probably buy
a keyboard or mouse extender cable. I wish I had thought of that - I
don't like soldering those small plugs either.

Hi.

<snip>

There are 2 reasons why I have used the FT-817 data connector. One is
the receive audio level is independent of the volume control.
Secondly, it avoids having to plug and unplug the microphone when
switching from phone to digital mode.

And the 817's data port isn't all that bad, if you approach it from
a different perspective. I hate soldering anything around DIN-like
plugs, so I bought a cheap PS/2 mouse at a local electronics store
(Fry's Electronics - for $4.99). I cut the mouse off the cable, and
then put a DB-9 on there in place of the mouse to work with my
KAM98 TNC. I threw together this cable quickly the Friday night
before ARRL Field Day, and had no interference problems when operating
in the forest with my radio, TNC, laptop, etc. Sometime I will make
some time to get a Linux PSK program working on my laptop but for
now even RTTY with the 817 is not bad at all!

If you wanted to use the narrow CW filter for digital modes, you
have to be in the DIG mode (RTTY, USER-L/U, PSK-L/U) to get to
it. This may not matter for PSK but could be something to consider
when working older digi-modes like RTTY.

Back to work.......

I am using PSK-U here. I don't use the narrow filter so the frequency
shift is not a problem. I guess I will change to user-u when the need
arises to use the narrow filter.

I also have a standard RIGblaster on my TS-570D for digital modes.
The RIGblaster is connected to the MIC input of the TS-570D and I use
USB mode. However, I have taken the receive audio from the TS-570D
data connector so that the receive audio level is not dependent on
the volume control. The standard RIGblaster has a connection for the
microphone so that pluging and unpluging the microphone when
switching from phone to digital mode is avoided.

Steve and others,

This is the method I am using, listening via the laptop PC speaker. I
can still control the rx audio without affecting the soundcard audio
when the PC speaker is enabled in the mixer window.

Nick, I saw your post and thought I would respond. I was under the

hooked mine up to a rigblaster yesterday evening but was not able to
set the ALC properly (actually I was not able to get any output out at

all ). Perhaps I did not set up the volume and related controls
properly.

Where did you see that the 817 expects ot see the tx audio at the data

connector? Your feedback would be appreciated..

Thanks..

Serge VA3SB

Actually Serge, I deduced this fact from the same problem you had. When
the 817 is in
digital mode, I had no PSK tones coming from the transmitter and no RF
output.
WHen I went back to usb, I had tones. I am using the Nomic with a cable
from the
Nomic to the mic jack and speaker jack to sound card.

After re-reading the book and looking at the pin diagram for the rear
digital connector
I assumed that when in digital mode, it wants audio in that port, not
the mic port.

So, until I get my RJ-45 to mini din cable made, I'll continue to use
the mic jack and
usb.

Someone posed the question in anther email and I hope to see the answer
soon. What are the
benefits of using the rear port and digital modes for PSK over the mic
jack and usb mode?


Hope this helps OM,

I tried to find this thread in the archives and never did.

If using USER, are there any other adjustments to be made?

What is the difference between USER-U and just using voice usb? I don't
have a narrow filter yet, I'd really rather have the Collins SSB filter
so I am in great hopes that I can get by without a narrow filter for
PSK.

Bill,

Thanks for all the info. I made my first PSK QSO with the SGC2020 and
Rascal interface, made several after that.

I then opened up the Nomic interface, arranged the jumpers and tried
again on 20m, 14070.

Yes, lots of signals there. I adjusted levels again (different computer,
different interface and different radio). When things looked OK I tried
the search and pounce method. Got a K6 to answer, then we lost the
connection.

So, I started looking thinking about the FT817 and went to the menu. I
had started PSK on regular voice usb. I switched to digital and PSK-U.
No output. After some reading it looked as if the digital modes need
audio to come in from the rear connector, so, back to regular ssb.

I had 3 to 4 bars of ALC, running through the Z11 tuner, no SWR to a zip
cord inverted Vee up about 30', the same antenna I used on the SGC.
Never did get another QSO going that evening (this was last Friday) so I
finally gave up. Been out of town all week and having company this
weekend so don't know when I'll get to try again.

But, assuming I am doing things correctly in setup and tone levels then
I know (via Ruby slipper intuition) that I will eventually have a QSO.

thanks,

Nick

Although I have not tried it myself, it appears (based on comments

by Steve and others) that you can connect your sound card output to
the microphone input. I imagine that means that the headphone output
has to be used for the sound card input, so that you can't hear the
PSK31 audio from the rig's speaker (which you don't need to do
anyway, and avoids listening to the above mentioned hootin' and
hollerin' from another station, should it occur). One disadvantage
of this might be that you have to fiddle with the volume knob on the
rig every time you set up for PSK31 operation, and you have to do
it "in the blind" since you can't hear the audio. With the data
port, you set it once via the menus and probably don't have to touch
it again.

73 de Bill, KR8L/7

Hi Bill, thanks for your response.
I've listened a few times via the headphone/spkr jack but never got
around to buying the parts for a full-blown interface or even just
patch cables w/audio attenuators. So, I checked out BuxComm's
website, & decided to order their Rascal kit -- only $25, and I'd
probably spend better'n half that on just the parts. Besides, I
ABSOLUTELY HATE trying to solder to mini-DIN connectors & this way, I
don't have to!

FWIW, when listening to PSK with the 1/8" stereo patch cord, I can
hear the rig's audio via my computer's speakers. I've probably got
some screwy setting in my soundcard controls or the Windows audio
mixer somewhere....

72 de Steve AB8JC

One advantage of this is that any incidental "hootin' and hollerin'"
that goes on in the shack is NOT transmitted, via SSB, on the CW/DATA
portion of the band. (One hears this occasionally. Of course, for
this to occur with the FT-817 you would have to have VOX turned on.)
That is to say, in the DATA mode not only is the data connector
selected for the audio input, but the mic input is disabled.

(I assume everone has already had the experience of trying to call
another station on SSB with the rig selected to CW or DATA.
Everything SEEMS to be normal, except that you have NO output. This
is real QRPppppp operating!)

Yes. I've only been doing PSK31 for about three weeks, but have had
good success. No DX yet, but several CONUS QSOs. A few have even
been with my outdoor "Every Day is Field Day" setup in the back yard,
running the '817 on the internal NiMH pack at 2.5 watts. I usually
look for a CQ to answer, but have also had responses to my CQs. (I
also discovered that 1700 mAH

When I first set this up, I listened to my signal on a portable
receiver, and it sounded OK. My first QSO was with an experienced
operator (W3HF; see ), and
he took a critical look at my signal and said it looked good, so I
have stayed with the settings that I was using for that QSO.

I think that if you are getting the proper output indications with
regard to ALC, Power Out, and SWR, and that your signal sounds good
locally, then you are probably getting out OK, and if you are able to
copy other stations then you are receiving OK. Also, MAKE SURE that
you are sending in BPSK and not QPSK. Finally, remember that QRP is
kinda like Ruby Slippers: if you have faith, it will work!

Really, the only problem that I have had was one evening when a family
of skunks ran through the flower bed next to my operating position!
(Which was horizontally polarized on a chaise lounge.) We ended up
with a momma and five babies, and they stayed for a couple of days
before moving on.

And with this setup you get consistent PSK31 QSO's? I tried and

never

got an answer to any CQ's. The ALC was
running 3 to 4 bars on the meter. Tones sounded good on transmit.

Any other tips appreciated....

I purchased a Cat5 patch cable and a 6-pin Mini DIN (PS/2) plug. I
cut the RJ45 connector off one end of the Cat5 cable and attached the
Mini DIN plug in it's place. There was some figuring out what wires
went where. However with the nomic schematic and the FT-817 manual
this wasn't too difficult. The Cat5 cable was not shielded. I would
have preferred it was from an RF shielding perspective but it doesn't
seem to be a problem.

Hope this helps.
