    Fortec 1.2m offset dish focal length discrepancy

    Thanks FaT Air. That would explain the discrepancy. Still curious as to why it's measured this way but I will go back to the store and measure from the LNB to the lower lip, I suspect it will come in close to the published FL.

    Fortec 1.2m offset dish focal length discrepancy

    A local sat supply store has a Fortec 1.2m offset dish that I want to use for Ham Radio moonbounce experiments. When I measured the focal length of the display unit it comes up close to 90cm however the datasheet says it should be around 72 cm. My calculation based on the formula FL=(width...

    Wanted: Houston Tracker IV

    I wouldn't have a problem fixing a V-box if it''s just bad soldering (typical Chinese quality). If it dies from a blown micro or other unique IC then that's a different story. Sticum, can you send me a few pix of your Tracker 4 ? Is it the full integrated receiver or just the controller like...

    Wanted: Houston Tracker IV

    I only see V-box 2's and 5's on eBay right now. Will they all do what I want or should I be looking specifically for a V-box 3 ? If I only want a 3, who else carries them ?

    Excellent ! But then I'm still curious to know what "P20" is on the display in the picture (referenced by the link).

    Wanted: Houston Tracker IV

    Thanks for the pix...very helpful ! I could probably modify one of these to supply 24v instead of 36v to the actuator. I assume the connections on the back are for actuator and pulse input !? F connectors probably set polarity !? So it counts pulses but does the display show the actual pulse...

    Wanted: Houston Tracker IV

    So then it seems there are standalone Houston Tracker controllers and Houston Tracker receivers (which may incorporate a controller), some with the same model number. That's nasty. 14 Karat, I'd be interested to see a picture of your "Tracker 4" if you can post one. I looked at the V-box...

    Wanted: Houston Tracker IV

    I saw the HT3 on eBay but I can't find any info on that unit. The HT2 is apparently similar to my HT1 which I suspect does not count pulses for position indication. I didn't realize the HT4 was also an IRD. Does yours look like this ? (Aluminum box on the bottom is not part of it.)

    Wanted: Houston Tracker IV

    Why a Houston Tracker 4 ? The Houston Tracker 4 is ideal for my application (ham radio moonbounce). I just want a standalone pulse feedback type controller with 3 or 4 digit position display and relay controlled actuator voltage outputs. I don't need a full receiver/controller (which is why I...

    Anyone have a Houston Tracker 4 that you'd like to sell ?

    Houston Tracker I manual ?

    Anyone know if the V-box can be made to work with a 24v actuator ? The ads that I've seen all state that it works with a 36v actuator.

    Houston Tracker I manual ?

    I was hoping to find a compact standalone box to move the actuator and provide a position readout. I guess I'll gut the associated parts from the Toshiba receiver that I already have and put it into a smaller box. Thanks.

    Toshiba TRX-80 w/ Video Cipher RS

    I recently acquired a Toshiba TRX-80 receiver in a BUD deal for a non-TV related project. It has a blue General Instruments Video Cipher RS "descrambler module" (model VCRS MOM) plugged into the back of it. Is this useful/ worth anything or is it old school analog technology that's no longer...

    Houston Tracker I manual ?

    After probing around with this Houston Tracker I it would appear that the position readout wants to see a voltage from a potentiometer as opposed to being a pulse counter. Does anyone know if the latter models of HTs (3,4,5 ...) use the pulse counter method ? Thanks.

    winegard sizes

    Replacement mesh I just acquired the same dish (in pieces) with similar damage to some of the mesh. I'd like to replace the damaged pieces. Where can I buy some from ? BTW, can anyone verify the specs for this dish ? Dia = 90", depth = 16", focal length = 31.6", f/d=0.35 Thanks.
