[TenTec] Pound sign (#) on Jupiter screen

I don’t think that is a memory status hashtag. I read the manual pretty thoroughly and did not find a reference to this.

Has the radio ALWAYS done this? 

I believe that  the hashtag is the loss-of-lock indicator.

Generally you should not be able to see this because the PLL should lock up quickly enough that you never get a chance to see it.

Does it do this on all bands?

The reason I ask  is that, if the # shows up only on one extreme or the other of a given VCO in the radio, you might need to recenter the trimmer in the VCO to promote faster lock-up.

Left unattended, I would expect the thing will drift to the point at which it will not lock up at all.

Just my input because I cannot find a definitive description of the use of the hashtag anywhere.
