I picked up one of these on a risk buy. The owner had no idea if it worked or not. I lucked out and it seems to work. Unfortunately it only came with one "band module" so I would most likely need to buy a couple more, I see there a couple on EBAY.

I have never seen or heard of this model and I am thinking of building a portable station out of.
I suspect that running digital modes would be difficult as this seems to drift in frequency a bit.

So I'm wondering if this is a waste of time and money (only $40) or a radio worth building a portable station around.
Anybody remember these?
Good and Bad?

Thanks

It was designed to be a portable radio. Why wouldn't it be suitable?  Wink

Specs from Ten Tec site:  http://www.tentecwiki.org/webarchive/555/

My recollection is that the sold well in the late 80's into the mid 90's.  Not fancy, but a simple rig, very small that can be taken around.  Besides, how many rigs this size had SSB at that time!

Also, although the frequency control is analog (an internal PTO), the Scout does employ PLL to phase lock that to a crystal reference, once the tuning is set.  So, it has the potential to be quite stable.

But as I recall, the design was a bit funky; it had very limited processor utilities and under some operating conditions the PLL could break lock and then you'd need to re-set the frequency.  I had a Scout a long time ago (when it was brand new) and I think I recall just using the internal keyer (CW) would disable the rig's ability to phase lock, so after sending a while when you stopped, the receiver could be on a slightly different frequency than it was before you started sending!  Or something like that.  Kind of strange.

I never used it for digi modes but did use it for CW quite a lot and it was pretty solid, good receiver, good modulation, etc.  But not as reliably stable as modern gear.

See the unofficial TenTec site for a mod to address the drifting scout

KA9CCH,
Great info !!!!!
I'll do that MOD to fix the drift and give it another shot.

Thanks,
Ernie
