No sir, I have not tried that.

Thank you so much for the update Ripley.
Sounds like you’ve done an extraordinary amount of troubleshooting.
Kudos to you.
Are you able to use the rig in Pegasus Emulation Mode?
Something of the likes N4PY rig control?

Hello Fernando,
This radio that was donated to us is said to have taken a lighting strike and
had/has multiple problems. The persons that worked on it before me fixed the
power supply protection circuit but when you turned it the transceiver was
receiving and transmitting at the same time. Not good. They tried a couple of
things but gave up.
Since joining the staff at the Museum I was asked to look at this radio. After
a few hours of bench time I isolated the “always transmitting” issue down to
the ADS micro-controller on the LOGIC/DSP card and replaced that 128 pin
surface mount beauty with its replacement that arrived in the mail today. The
new chip fixed that problem but not the VFO issue. Channel B on the encoder is
fine but channel A is at Vcc level.
I was finally able to see the marking hidden by the ribbon cable and the
encoder that I need is a HRPG-ASAC#17F made by Avago. This particular encoder
is a non stock item from about everyone (minimum order 150 units and a 14 week
delivery). I did find a similar encoder from the same manufacturer at Newark
Electronics in the UK. This encoder has a cable instead of pins for a front
mount circuit board application but I believe that I can adapt it for my needs.
The encoder is about $40.00 and I should receive it in about a week to ten days.
Right now the radio works except for the VFO. 100 watts out on CW, auto antenna
tuner works, all of the front panel buttons seam to operate correctly and all
of the other encoders work fine. This evening I found and fixed a problem with
the PTT line. Turned out to be an open diode on the LOGIC/DSP board but then
discovered that the ratty Ten Tec hand mic that they gave me to test this radio
is bad or has a broken wire to the microphone element itself. I will check that
out tomorrow.

Subject: Re: [TenTec] Replacement VFO encoder for TT Jupiter
Sad news.
One way to find a replacement is to get any info from the one
in the radio.
A search on the parts list yielded this: encoder hrpg
A google search shows than Mouser has one for $32.
A prudent thing to do is to ascertain that is what is written
on the old one before ordering. Less than that I think the
only thing else to do is remove the old one and try to match
its characteristics with what is available.
A long shot would be to contact Ten Tec.
A have two Jupiters here and very interested in how you
fair out. Let us know.

Hello there.
It looks the VFO encoder on our Jupiter has gone south. Spin the knob all that
you want and nothing happens the same is true when the MENU screen is pulled
up. Anyone know where I can get a replacement Encoder for this transceiver.
Thank you in advance for your response.
