[TenTec] Replacement VFO encoder for TT Jupiter

[Bob Ripley]

Hello Jim,
The short answer is I don’t know. I do know that they do not sell boards for the Jupiter. On a whim I sent them another email asking Ten Tec Support is they had a VFO encoder for the Jupiter and this time the answer was yes. Does that mean that are stocking parts again or just selling off the parts that they have left? I don’t know.

Email is the best way to contact the Ten Tec Support folks.

The words are mine but this iPad does what it will with them.

 Bob,  Congrats on getting the radio up and running again, always good to hear of another rig coming back to life..
 A general question however..  Has Ten Tec began selling individual repair parts again?  If so what is the contact
 info for parts ?    tnx.  73, Jim  W3KA

This story has a happy ending.
The VFO encoder that I need arrived from Newark but I didn't use it. Turns out that Ten Tec had the exact replacement part in stock so I ordered a VFO encoder from them. It showed up yesterday and I installed it last evening. The new part brought the VFO back to life. After some performance testing I put the radio on the air this evening and made a contact with Ray (KB5PX) in Louisiana. Ray gave me a good signal report despite the dense contesting traffic up and down the 75m band.
I'd say that this radio is good to go and ready to return to the Radio Museum.

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.

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.
