Minitiouner Software/Graph Studio.

[GW4ZVL]

I am new to ATV. I have the Minitouner board built and am trying to fire it up. I understand I need to copy file(s) from Graph Studio - the latest version. When I try to download it I get a message that the file either does not exist or I do not have permission. What do I do? Help please.

Don't. I assume you are running Minitioune. It is no longer supported. You might find the right software somewhere, but a perfectly good alternative is to use Opentuner which does more, or if you do need to use Minitioune select VLC instead of Graph for the video.

Edit, you will need to install 32bit VLC, as per the manual, if you have not already done so. Sorry I can't post an image, the software won't run with no tuner connected.

As Mike says it is no longer supported, but it is still usable and many prefer it to OpenTuner.

If you would like to contact me directly via contests(@)batc.tv {remove the brackets] I'll get you going.

Thanks for the suggestions. I will track down Opentuner. Is that the one from ZR6TG? Also can I have a LNB for use with narrow band QO-100. Can I plug this into Minitioner? I have been operating on HF for decades and QO-100 CW more recently so ATV is new to me - I appreciate the help.

Yes it is Toms software. If the LNB you have been using for NB was good enough for NB (Bullseye brand or Octagons with external ref modification) you will be fine for DATV on QO-100, other than having to provide the alternative LNB voltage (12 or 18V) or rotate your LNB 90 degrees. This voltage is selectable in Opentuner and you could then take a feed from a splitter to your NB rx. The Picotuner includes a current limited PSU for providing that making it simpler.

Good luck

For what it's worth I do this differently. I have a quad output LNB modified (but of course this mod is not necessary for the following functionality) to accept a GPS locked reference. I have current protected power sources for both horizontal and vertical polarisation by the dish running all the time, fed to two of the other LNB connectors and hence the one LNB outputs for both narrow band and wide band reception all the time. So all done with no mechanical switching and only two cables from the dish to inside the house. A decent LAN cable and a single coax for the LNB.

I can receive both narrow and wide band on QO100 whilst transmitting on either narrow or wide band at the same time. All with one dish and no switching. There's no mechanical PTT switching either, I keep it as simple as possible. I use a Pluto by the dish and both Tom's excellent Open Tuner and the earlier Mintioune software and SDR Console for narrow band on Windows 10.

I used to do that, I modified the 4 sockets to be reference, 12V in, Vertical out and Horizontal out. There is no need for 18V because you can hard wire the polarisations. Unfortunately that LNB failed in the end. I replaced it with a Bullseye. The interesting thing was I got a dB higher MER on the beacon (12dB vs 11dB) and wider bandwidth signals with the Bullseye. This is reference phase noise, not the close in that's removed in the PLL, but the further out phase noise. Most probably won't see this as they have smaller dishes 1.2m or less and the band noise is dominating, but in Bazil's case, the same might apply.
