UT-100 series DVB-T TX, RX, RTX USB dongles

Hi All.
I thought I would start a new post to follow on from http://www.batc.org.uk/forum/viewtopic.php?f=15&t=3158, not being the first to try these great little devices.
I have recently received a UT-100C (US$160) and UT-100D (US$80) (http://www.hides.com.tw/index_eng.html) and downloaded V2.2 software from https://drive.google.com/folderview?id= ... sp=sharing
Using the rabbit-ear antenna that comes with it, I managed to get the ut100c going, streaming a video (converted with CyberLink MediaEspresso), using TSplayer. I used the Australian standard modulation settings and worked within the 70 cm band.
In Australia, there is a 7 MHz channel on 70cm and four on 23cm (WIA band plan). As such it is possible to receive with many TVs and set top boxes. I have yet to try the narrow-band DBV-T, although it seems to work ok, being the subject of the earlier topic.
I was able to receive with a conventional USB TV dongle, a Terratec Cynergy Stick+, that I had been using as a software defined receiver (SDR). The distance between them was only about 5 m, but I haven't tried any further. It also works on a conventional Panasonic TV, even comes up on the guide.
I had trouble getting my web-cam to stream via PC2TV. I use the same modulation settings as for TSplayer, but was getting "Transmitter init failed". Tried some of the settings I found on the web (my German is not good) and eventually got it going for video only. Reducing the bit rate, under the encoder tab of configuration, is the key. 2000 was suggested and worked but was jerky and significantly delayed. Reducing it to 200 or even 100 variable bit-rate gives a smooth picture and a fraction of a second delay; close enough. Video quality still seemed ok. I am only using a Logitech webcam, so I don't expect studio quality.
I can't get audio to work with PC2TV, but I think others are having the same problem.
The desktop view of PC2TV gave me some problems initially, but I obtained a driver for it from Hides and it works ok now. .
I am building a 5 W amplifier from http://www.minikits.com.au/ to get beyond my 1 mW. I am told the 5 W rating is for narrow-band FM. With wide-band D-ATV, the output is only 500 mW, still a significant improvement.
I have recently returned to amateur radio after a 40 year absence. I ran a 2 m simplex station with a converted taxi valve radio while at high school. I am in the process of putting a new station together, tower, antenna etc. So I have yet to try DVB-T other than in the lounge using the supplied rabbit's ears antenna.
The dongles from Hides are use devices and software from http://www.ite.com.tw/EN/products_more. ... 2&ID=4,152
The UT100 series DTV-T dongles are remarkable in what the can do, at a very affordable price. Just add power amplifier(s) and antenna (and a bit of patience)!
