Strange PSIP From Digital Stream DTX9950

[indysteve]

While DXing this morning, I was using the Zenith DTT900 (no analog pass-through) and the Digital Stream DTX9950 (with analog pass-through). I've been using the Zenith/Insignia units since they first arrived while this is my second DS unit, but I haven't compared it that much next to the Zenith. Both units were being fed via a two-way splitter from the same antenna.

Early in the morning, I performed several "Update" scans on the Digital Stream. One of those early stations included WHIO-DT 41 (7.1), Dayton, OH, a CBS affiliate. Later, the Zenith decoded WETP-DT-41 (2.1), Sneedville, TN (first pic below). I then manually punched in channel 41 on the Digital Stream to see if it would/could locate, decode and display WETP. Yes, it did fully decode WETP, but when I checked the PSIP, I was very surprised. The new channel banner displaying the PSIP for WETP was all correct EXCEPT the call letters. The receiver was still holding on to the WHIO call letters. WETP proceeded to fade in and out several times for around an hour. Everytime it came back up again, I expected the calls to change to WETP. But they never did (pics 2-4 below). I've never seen this with any other DTV receiver since 2001. Very strange.

I have a Digital Stream, and though I have yet to experience what you did (two subsequent different stations on the same RF channel), it sounds like it doesn't update the PSIP in that situation unless you delete the first station from memory. (Which you can't do manually on the DS -- you'd have to do a rescan and let it delete the first and pick up the second). Sounds quite inconvenient from a DXing standpoint!

The DTX9950 likes to grab and hold anything that it decodes in memory - that's why it is
used for "regular" (non-DX) viewing - and even then it has some Victoria, Corpus, and Brownsville channels stored in it. KVBC-DT-2 mapped 3 in it co-exists with KIII-DT-8 also mapped as 3. My DTT901 (for DXing) only has the locals stored whose RF=Virtual (KLRN-9, KBNB-10, KSAT-12, KPAX-26, KWEX-41). If I need to look at the EPG for any of the other locals I just momentarily "store" it.

Pat, didn't you receive KVBC-DT2 once on a Digital Stream? I'm considering one of those DS units from Radio Shack for a second Es receiver.

It was just too frustrating running two Zenith DTT901s (with the same remote) for Es during the summer. It paid off by bringing me multiple stations a few times, but it was too much of a challenge.

Yes, the DTX9950 decoded and stored KVBC-DT-2 while I wasn't looking one day (the exact date and time are thus not known :() in early July. It also put their two other subs in its memory. I never got KVBC decoded with the DTT901.
