Question for you guys. This DDS Kit wants 5V for the Encoder. I'm planning on using a 7805 Regulator to provide that 5V since I am unable to find 5V in the radio. I am going to need to mount it to something and that means chassis. Can you mount a voltage regulator with-out insulators to ground (Mount the tab with screw, washer and nut) with-out creating havoc?

How much current does the DDS pull? You may be able to get away with a 78M05 in a TO-39 package. If a heatsink is required, there are round snap on heatsinks that are just air cooled. I believe, without looking, they will do around a half an amp. The good news is with the snap on heat sink, a chassis mount is not required. There are also heatsinks available for the 7805 that does not require sinking to the chasis. Obviously, it just depends on the current requirement and how much heat you need to dissipate.

That reminds me, if you run into Don WØDM in your travels and travails, tell him I said "hi". We used to communicate, on & off, but somewhere along the way fell out of touch. Good guy.
I used to get the Boulder ARC club newsletter (on exchange with mine) for awhile; that too fell into the cracks somewhere along the way. Pity, too, it was a good read.

Quoting from a manual I have open at the moment:
"Ten-Tec's service department can repair and service virtually everything we have built going back to our first transceivers in the late 1960's. It is our ability to continue offering service on these rigs that has led to their re-sale value remaining high and has made a major contribution to our legendary service reputation."
Read those words CAREFULLY, RKR...and reconsider your ill-advised decision to terminate service and parts support for those legacy products.
Ask any Harley Davidson dealership where the lion's share of their profits come from. Hint: It isn't from the sales of new units. With few exceptions, I can stroll down to my local franchise and get a 1985-up Big Twin piecemeal from their service spares catalog.

An interesting bit in the Swap section of QTH, posted a few days ago. Guess T-T cannot provide repair parts - specifically, the CPU - for an Orion. If the same can be said for the O-II or the Omni VII...things don't look good.

Take your time. I have tucked some funds away for you and hopefully it will be enough. If not.... I'll have to pilfer from the Wal*Mart fund and we all know who that enrages......
Just send me an email when you're ready Ron.
I'm taking my time with this Omni..... scary stuff here....
