DR HD D15

As evidenced by its menu the Dr Hd D15 is a very well equipped receiver and I have grown to like it. My only misgivings would be its tuner sensitivity and not being able to change the orbital degree positions for all satellites. The latter can be remedied with the Clark Tech editor which I posted yesterday. The infamous Dr Hd F15 and its extremely sensitive tuner, as posted across the pond, is a unit I would like to obtain but I have only found one Russian site that sells them and my e-mails have gone unanswered.
 
I sold my D15 to my neighbour, I have been told that the D15 and TM 5402 have the same tuner. The F15 and TM F 3/5 are also supposed to have the same tuner as well. After testing both manufacturers, TM is my preferred brand.
 
The receiver is pretty neat with the spectrum analyzer. I am able to zoom in to a sliver of the band and narrow it down to each transponder. From there I can lower the graph in order to tune everything at once. The signal meter goes from 0-255. Everything on my graph right now on 99w is around 110 or so. I am not clear on what unit is represented in the scale. The bandstacked lnb doesn't work right with this. Similar to the old coolsat and the x2 where it double scans everything. I see in the scanning it will show a 2db signal in the scan but won't lock it. It seems to be able to lock around 5 but sometimes will stay red at 7.5db and not lock.
 
I noticed that locking tp under 5 db was a chore for the Dr Hd units. Technomate will lock with a db signal of around 3 although the tuners are supposed to be identical, I beg to differ.
 
I am running the 144 firmware on it. There is a known bug where you can't change satellites while using the spectrum analyzer. This is no biggie to me as long as the analyzer works. The case size is the same length and width as the Cryptobox.
 
I have been getting an orange signal meter for the signal. Sometimes it is red. Is it supposed to be green usually? I may have to replace a section of coax or a switch. It doesn't like to lock transponders less than 5db or so. I am hoping that with a better signal it will lock with a lower db reading.
 
Ive been testing this receiver's scan against my other blind scanning boxes and while it is a bit slower, it is consistently scanning in more channels than all of the receivers tested so far. I have over a 100' cable run through multiple switches and couplers, etc but this box is definitely a keeper.

C band or ku Rob? I noticed both Dr hd units on ku blind scan would scan in dummy tp with excellent signal but no audio or video.
 
Both, I was mainly testing my fixed ku dish at 103w and my 7.5' SAMI at 58w. It is most effective on 103w ku with all of the news feeds and how the transponders are spaced. Some of the channels that were weaker it had a little better luck showing a picture. I am running the 144 software. It seems to need about 5db in order to lock but I am going to try and run a direct coax to it and retest it.
 
So far the only strange transponder that this is picking up for me is on 91W KU and that's because it scanned in a stronger Bev transponder. Probably a bug where it will scan an encrypted transponder on a fta scan.
 
I figured out how to change the oribital position of the satellites in the receiver. You go to dish setting, then toggle to DiSEqC motor. Change that to USALS and press enter. Then scroll to Sat Degree, it will say 0.0E or whatever, there you just type in whatever you want and save it.
