No, actually you hit it pretty much on the head. I talked to another
ham that told me that he used a GD-6K on a TS-520S and that it hooked
right up to the 3 connectors, plus the power connector. It seems the
Grand Systems GD-6K was a reply to the Kenwood DG-5 external display. (I
won't say rippoff.. LOL) ..
Now I found an online manual of the DG-5 and it read, it said:
________________________________
The TS-520S operating frequency is made up as:
of = HET-(VFO+CAR)
In the The DG-5 where two counter circuits are connected in series, the
heterodyne signal is fed to the lower counter. This lower counter
subtracts 10MHZ from the heterodyne frequency in a digital way
(HET-10MHz). The subtracted frequency presets the upper counter. The
other signal fed to the upper counter is composed in the manner that the
carrier frequency is mixed with the 10MHZ reference frequency and the
resultant is further mixed with the VFO frequency. [(10MHz-CAR) - VFO].
The signal is added to the one preset by the lower counter, that is:
[(10MHz-CAR) - VFO] + (HET - 10 MHz) = HET - (VFO + CAR)
As explained above you will find that the DG-5 should display the
correct TS-520S Operating frequency. The reason of using such a
complicated construction is that if the GD-6K is the same as the TS-520S
in the construction, this can produce a signal of the same frequency as
the receive frequency. The signal interferes as spurious with the
operation of the TS-520S.
(1) HET Connector (H) - The HET connector is used to input the
heterodyne local signal of the TS-520S. To connect to it, use the
supplied signal cable.
(2) CAR Connector (C) - The CAR connector is used to input the carrier
signal of the TS-520S. To connect to it, use the supplied signal cable.
(3) VFO Connector (V) - The VFO connector is used to input the VFO
signal of the TS-520S To connect to it, use the supplied signal cable.
(4) Digital Frequency Display - Six digit 7-segment light-emitting
diodes (LEDs) illuminate input frequencies in digital way. The leftmost
two digits are in units of MHZ, the succeeding three digits of kHz, and
the right most digit of 100Hz. These are section by two points.
(5) Power Connector. 13.8V, 0.9A DC Power Connector - This connector
supplies the TS-520S 13.8V, 0.9A DC Power into the GD-6K. For
connection, use the attached power cord. It may also be connected to
other power supplies of the same rating, for example, the KENWOOD Models
PS-6 and PS-8.
__________________________________
Now all of these connectors connect to the Grand Design via three RCA
jacks, and a keyed power cable.
My only real question at this point is in reference to this Post I found
on the internet:
I found this message on forums.QRZ.com and it read, it said:

One of the wires came loose from the plug in to the eight pin remote

helpme figure out where that wire goes? I got the rtadio used some years
ago, and there are no instructions.
Thanks

So how did this guy get the unit hooked up to a TS-820, there are no
connectors on the back of the unit???
Well, any Idea's would be welcomed!!!
Thanks!
