    VBox eeprom

    With regard to the number of writes to the eeprom, it is even greater than I inferred earlier, i.e., "This writing of current position has to be accomplished each time the dish is moved" and my meaning was it writes to the eeprom only after each stop. Not so! As a result of this discussion my...

    VBox eeprom

    The chip referenced above is the one used in the VBOXII, not in the VBOX7. To get the spec sheet (or a seller) for that used in the VBOX7 Google (or Ebay) search for L24C02B or 24LC02B.

    VBox eeprom

    Granted, each receiver SAVE simply records a satellite position, and, yes, that is not done very often, but, each time the dish is moved the VBOX keeps track of current position and from our information by observation that is recorded in bytes 246 and 247 of the 256 available bytes on the...

    Actuator Losing Count

    I recently had a problem with a VBOX7 losing counts and resolved it as noted in this posting.

    Certain Channels need to be "primed"

    Update on priming problem: The Pansat 9200HD with an ARM processor appears to have the same "priming" problem when moving from 97w to 125w. Thus, the Ali processors are not the only ones.

    Certain Channels need to be "primed"

    Thanks Titanium, both of my receivers have ALI chips and your comments are confirmed. My friend has a Pansat 9200HD which is not an ALI processor (Conexant) and I asked him to try it with that unit where his Linkbox is having the "priming" problem on PBS at 125W. Interestingly I have never had...

    Certain Channels need to be "primed"

    Often when I tune to an abc feed (say 4120 H 30k) on 99.2°W the channel fails to appear until I tune to another channel like FOX (Mo) (3720 H 8703) and then switch back to it. This also occurs on the 16aspk channels (3980 H 30k) and the very high quality 7 channels (3940 H 30K) on 97°W. On...

    c band reception with ku lnb?

    If you supply power to both the C-band and Ku-band lnbs on the same dish at the same time and the incoming IF path to the receiver is common (after a Diseqc switch) you will receive the strongest of the IF signals showing up whether C or Ku. For instance this happens when using a 922 to power...

    Pansat 9500 vs 9200

    While the 9500hdx does not include a terrestrial tuner, my experience has been that it is a very polished and trouble-free product compared to my two 9200hds. Failure of a 9200hd can usually be attributed to power supply capacitors. I had one fail and the caps, while static testing good...

    Pansat 9500 vs 9200

    Having owned 2 Pansat 9200hd receivers I like my Pansat 9500hdx for the following reasons: 1 Both 9200hd units had heating problems (which I resolved but they still required fans - methods). The 9200hd processer always runs unless you totally remove power via the switch under the front...

    Official 4DTV Conversion to W5/X4 services only infornmation post

    I somehow lost the X4 satellite mapping on my 922 yesterday, April 13, 2011. Finally, after many tries, I ended up retrieving the proper mapping with the following actions (possibly not in perfect order here): 1) Changed my LNB settings to C-band only (they were C-band/Ku-band)...

    Experience with the Prof 7300 PC card

    It would be neat if Pansat had included an added switch to separate the hardware front-end choice from the data stream software choice to provide an “S” picture, not that it would normally be any different. Well, the “level” comparisons were interesting. I did a Pansat 9200hd-S2+ blind...

    Experience with the Prof 7300 PC card

    On the contrary, one can use the DVB-S2+ tuner (on a Pansat 9200hd) for the DVB-S signals. To demonstrate this one only needs to set up a second transponder identical to the one used for a given DBV-S signal and change only the tuner to be used in that second TP. For instance, push MENU...

    Experience with the Prof 7300 PC card

    I would suggest any cpu found on the following chart: PassMark Intel vs AMD CPU Benchmarks - High End After you choose a cpu then any motherboard that can handle it will do the trick with a couple Gigs of ram. My cpu has just fallen off the bottom of that chart in the last month but is still...

    Experience with the Prof 7300 PC card

    Comparison of the 7300 and 7301 "front ends" First, I must mention that the Prof 7301 and the DVB-S2+ upgrade for the Pansat 9200hd have a common "front end" demod chip (credits are below). Thus, this comparison is actually between a Prof 7300 and the Panast 9200hd with its DVB-S2+ upgrade...

    Experience with the Prof 7300 PC card

    pendragon - While the basis of those figures likely differs between the Pansat and the 7300 (and cannot be compared precisely ) each set does indicate their builder's confidence in what is seen and what is derived from the signal. The relatively small difference in level correlates with the...

    Experience with the Prof 7300 PC card

    I have seen no definitive information comparing the signal to noise or stability of the Prof 7300 and 7301 cards although likely such exists. My experience with the 7300 indicates it has a far better front end than my Pansat 9200hd. As a comparison using the AK-1 channel on satellite AMC-8...

    Experience with the Prof 7300 PC card

    Significance of 7300 "relative stability" The card (7300, 7301, etc) front end "sensitivity" (s/n and stability) is only one piece of the puzzle. It is an intermediate stage in the signal path. A more vunerable part is the sensitivity of the front end of the system, i.e., the lnb quality and...

    Variation in quality of HD As stated the FTA CBS bit rate was about 32 - 36,000bps according to ProgDVB and the OTA CBS HD does have a FOX SD subchannel. Thanks for the heads-up on exactly what was going on. I was aware of a wide variation in bit rates on "HD" FTA channels but paid little...
