Touchstone — Rf Spectrum Analyzer Software With Dvb-t Dongle

Has anyone tried the Touchstone software on a generic DVB-T dongle?
http://rfexplorer.com/touchstone/
The monitored frequencies mode looks very interesting for tuning a dish. This would put a nice basic spectrum analyzer within reach of any satellite hobbyist!

I see that it is sold bundled with a DVB-T on Ebay and have no reason to think that it wouldn't work. I am willing to become the guinea pig if it hasn't been tried.

I finally was able to pickup a DVBT for like 7 bucks on amazon and gave this little guy a shot. This works amazingly awesome. No receiver is required but you do need to get power to the LNB. I am fortunate enough to have one of those 13 to 18 power inserters so I was able to get power to the LNB that way. This works very well and all you have to do is find the LBand frequency's. This even works with ATSC signals in the UHF and VHF range. Technically any signal in that freq range. I just wish that It did the full Lband sweep versus 300 mhz only, but irregardless it will get you on and you can fine tune from there. This is a very nice setup and you dont need to spend 3,000 plus on a spectrum analyzer. You cant beat the value of 7 bucks and free software to do the job.

Now, is the paid version worth it and whats the differences?

K9SAT: Interested in your use of the spectrum analyzer for the L band; what type of antenna is used for that? Yagi, discone? Anything interesting on that band?
By the way, I never used the free version, but I have the paid version, it's great. I am doing something similar to you on the Ku band to see what the transponders look like. I can see them but don't know how to interpret them :)
Thanks.

I am using a satellite dish and LNB and using L band differently than scanning for anything open in that 1-2 ghz range through the airwaves.
L band, also referred as the IF signal is the frequency going down a coax cable, usually within the 1 - 2 Ghz range.

Example:
1. The LNB receives the downlink transponder satellite signal at 11700mhz and subtracts the LO frequency of the LNB of 10750 and outputs an IF or L band signal of 950mhz.
  • DL - LO = IF (11700 - 10750 = 950)

2. The IF signal of 950mhz travels down the coax to the satellite receiver or analyzer.

K9SAT,

Thanks for the reply, that makes sense. Am doing the same thing with Ku band, have a Universal LNB on a 30 inch stationary dish and can switch LO (9750 or 10600 MHz) depending on what the requirements are. Not too many Ku stations I know of that need that lower frequency LO other than some FTA stations on 45W, at least from this part of the country. Right now the dish mounted is on a wooden pallet on the ground with concrete blocks and pointed at Telstar 12, 15W.

For Telstar 12 the downlink frequency for TVGE and TPAI is 11964 MHz minus the LNB LO frequency of 10600 MHz which = 1364 MHz. With that in mind I have been scanning from 1200 - 1500 MHz using the dongle spectrum analyzer to see what appears on the scan for this satellite. So far so good. But I want to scan both vertical and horizontal polarities and also switch on/off both LO frequencies to see if there are any other hot transponders on this bird. Just for curiosity sake. I know sats transmit many different types of data, etc. Not interested what the data is, just want to see what my STB is not seeing.

Am using a Channel Master CM-1007A satellite meter to provide voltage to the LNB and have the dongle analyzer connected to the meter's output. This meter is great in that you can change the LNB voltage from 13V to 18V for polarity. Can also manually turn on a 22 KHz signal to switch LO frequency.

Am I the only one that hates what Dish did to their mobile app?

I thought I would come here and find lots of complaints about the update to the dish anywhere mobile app, but am not seeing any. It used to look just like the desktop webpage. Now you can no longer filter by sports channels or movie channels. Plus that they made it look like a big button telephone and you see fewer channels in the screen which requires more scrolling. Yes I realize you can look at sports then select which sport you want to look at, I just liked being able to see all sporting events in the guide with all other channels being filtered out. Am I alone in the wilderness on this?

I'm not a big fan of the new layout, especially on my Apple TV. It used to look like the old Guide layout on the Hopper 3, but they changed parts of that, too.

NCIS

Anyone else watch this show? Any guesses as to what was in the box Gibbs gave to Abby that was on her desk? It look liked it was glowing.

I also heard that someone was leaving the show at the end of this season. Any guesses as to who thats going to be?

No. Bring in someone new.🤔 Tony is not serious enough for me. Parker is too close to the team and Tim is too young to take over IMO.

I don't think Tim and Tony are that far apart in Age ...

Remember what Tony said to Tim when they first got back together ...
Tony said: I am the New Tony, Tim .... (something to that effect)

Tony has changed, he's been running his Security Business ... I'm sure he has grown up.

Give it time ... your judging the New Tony from the old Tony.

It sounds like Tim won't be around the Team much longer either.

Trailer for new Jim Caviezel movie Ghost Soldier

Might be worth a watch when it comes out. Looks like typical big corp against the little guy movie BUT....there is a reason this plot type is so oft repeated, it draws audiences.

Project Hail Mary

If you're going try to read / listen to the book (can't recommend the audio book enough) before this comes out, I'd avoid trailers.

Trailer below, spoiling it to make sure you read the above bold message first. The book / audio book are fantastic. Go into this blind if you can IMO!

Kind of disappointed at how much they show. A lot still to see, but man, some good reveals in the book that are just served up here.

Forgot to comment. I did watch when it first came out on MGM. I enjoyed it a lot. I think reading the book made it easier to watch. Several friends commented it was a little hard to follow.

I agree. That can go for pretty much any book vs movie. Back when I was single I would read any Stephen King or John Grisham book I could get my hands on. When you read a book you make up the scenes and characters in your mind.....the movie version always disappoints.

A big win for the Patriots, and they are now 3-2.

Browns lose a close one with... The Jets. That is a classic Browns loss (granted, any loss is a classic one it seems). 49'ers, Vikings, and Chiefs remain undefeated. The AFC north have a three way tie at 3-2 for second place. :eek:
