I have the best antennas and the best preamps. I am not getting 50% of the signal to each Tablo tuner since these signals show very high SNR on my Hauppauge signal meter.
I have put two Homeworx on a splitter and STILL get the channel the Tablo doesn’t. How do you explain that one?
The Homeworx is one tuner but the signal going to both has a very low noise preamp which is quite strong as measured by my Hauppauge meter.
BTW I have put two Homeworx on a splitter and STILL get the channel the single Tablo doesn’t. I have a Homeworx in two rooms.
Are you saying that there is no amplification in a Tablo to overcome signal splitting?!?
If there is, remember that the dual Tablo has a 4 way split, not a 2 way. So my Tablo is dividing the signal by 4, not 2.
Also any amplification raises the noise level. Internal amplification within a Tablo will also add noise to the incoming signal. If for example, the Tablo amplifier ups the signal level by 2 db but adds 1 db noise while losing a certain percentage of the signal due to the split, what is really the overall effect? My Samsung TV has an internal amplifier of 2 db (which is why I used that as an example). What in fact is the quality of Tablo’s internal amplifier?
PS Did not mean to hijack @RetiredEngineer’s thread since I brought up the Homeworx as an example of an inexpensive backup to the Tablo to ensure failproof recording.
BTW an another alternative way for getting a specific channel is to make an antenna tuned to that specific frequency. For example, in my circumstances I’d make a 4 bay with 10.75" whiskers for FOX or 9.5" whiskers for ABC. Done that kind of customization and it works quite well in resonating to problematic frequencies. And add a preamp also tuned just to that particular frequency (Jan Jenca make those and they are not expensive).
This is the only reference I could find regarding an internal Tablo amp:
I have 2 antennas feeding my Tablo 4 Now… yagi directional with a preamp and a multidirectional with amp included.
I played around with many antenna schemes tweaking for quite awhile.
I do like this special antenna idea though.
I would specifically use it with one of my HDHomerun tuners to pull in the one channel
Will investigate further.
Thanks

When I first realized that I needed an antenna specifically customized for a particular frequency, I got my inspiration from this site:
https://m4antenna.eastmasonvilleweather.com/index.html
https://m4antenna.eastmasonvilleweather.com/Drawings/PDF%20Drawings.html
Too expensive to buy a custom manufactured antenna. I built one specifically for my FOX frequency using the dimensions for whisker length and spacing suggested by this site from materials I could get cheaply at Home Depot. It worked quite well because that station went from a 17 SNR (marginal) to 25 (stable and useful). That really got me thinking about the phenomenon of frequency resonance for antennas.
Since I didn’t want to overdrive all the other frequencies, I got a preamp from Jan Jenca specifically for that frequency:

All the other stations are on a different antenna\preamp. Joined the lot with a Jenca channel custom combiner:

Altogether came out to about $100 to be able to get FOX reliably and stably.
OK, over and out @RetiredEngineer, back to the “Tablo Update 2.2.18 Problem Recording” issue and good luck…
This topic took a few turns since I last checked in 
Just wanted to update on the recording issue. A few days after Tablo support accessed my logs and posted their message here acknowledging the issue, Jeopardy began recording again on Sat 3/3. It missed Monday 3/5, but has recorded every episode since thru yesterday Sat 3/10. I notified support accordingly.
It still shows I have many more previous recordings that I can’t access, but things are moving in the right direction. Thankfully I also have a streaming service with their cloud DVR so I was able to access those recordings there. We really prefer Tablo’s DVR functionality tho, much easier and accurate to fast forward thru commercials and such.
Also, never thanked @SophieCat for her deletion clarification - thank you!
My wife’s recordings have been working since Tablo support logged in also. The recorded shows counter isn’t correct, but at least the shows that did record are now listed and available to watch. My wife also seems happier towards Tablo now.
Last I heard from Tablo support was they didn’t apply a fix, but it does seem like they did something to get our DVR working better.
Update:
We’re working on testing a solution for this issue now, and we’re hopeful that we’ll be able roll this out soon. As soon as we’re ready, we’ll contact you via your support ticket to process the changes.
I’ve had the same situation with Good Morning America not recording and showing a “blank”/white block in the recent recordings or in the “All” recordings view, it says that there are no recordings. I rebooted my Tablo, and it recorded yesterday, but this morning’s segment went back to the white block/no recording label.
@misdiva, sounds like you have the same issue I reported. I’d get a support ticket created ASAP to get it cleaned up.
Same problem here. I have three “blanks” in my Recent Recordings, and a show listed… but with no episodes on the thumbnail.
I have recording showing that they are scheduled to record but the time comes and goes and no recording. Looks like 2.2.18 is a problem.
I am experiencing the same problem with shows randomly not recording on my 4 tuner Tablo. How uninstall version 2.2.18 and reinstall version 2.2.16
Thanks for your help. Hopefully this will solve the problem.
Hey all,
We managed to narrow down this problem, and we have a fix available now. We’ll be including this in our next update (coming soon, no dates yet).
But for those of you that see an airing counter in the ‘Recordings’ screen - but are unable to access the actual series or episode - give our team a shout.
We can set up remote access and apply the update to solve the issue so that you don’t have to wait for the update.
