I had another light bulb moment!
First: The RF range for the pan and tilt functions (NOT the camera signal), is real short.
so I took the P/T apart and tried to see if the receiver could be tweaked for better performance... no luck.
SOOO.... (and here is my LBM (light bulb moment))....
I have a few of the NEWER TM751 (the plug in transceivers) with the HiMark receiver chip, that seems to have great range.
It only requires 5 volts to operate. There are three solder points on the board... Gnd, +5, and D (digital data out).
There is a fourth solder point for the antenna... soory.
This is the same receiver that is used in the CM15A (and probably CM19) and seem to have great range with the antenna mods found around here, even with the 9.25 or 18.5" antenna.
Sooo.... why not swap out the Ninja's receiver board with the one that is in the TM751! True, you no longer have a functioning TM751, but you CAN use it as a "any house code" / Unit code 1 appliance module, so it isn't really completely useless!!!!
It also has a regulated 5 volt ps, so you could use it as a plug in transceiver for a wireless motion detector transmitter (making it a wired motion sensor).
Just find the "data output" from the xxxeye's processor and input that data to the now removed "data input" (where the TM751's receiver's data output used to go), find the +5 and gnd, and wire that to the battery + and gnd on the motion detector.
The MSxxx's processor has a nominal operating voltage of 5 volts... X10 is running it at reduced voltage of approx. 3 volts, so it will work just fine!
Then take the HiMark rcvr. and carefully solder the white (+5), black (gnd), and yellow (data out) to the ninja, and carefully mount it where the old rcvr. board used to be. SEE NOTE!!
The board is the same width but a little shorter than the old board, so hot melt glue will work wonders!
The antenna can be routed under the controller board and out the bottom where the power cable comes out, and under the strain relief (it will be pinched a little, but no harm done).
You COULD wrap the antenna around the innards like X10 did with the old antenna, but your range may decrease a little because the antenna is not extended.
NOTE: BE VERY CAREFUL NOT TO CHANGE/MOVE/SMASH/DISTORT THE COIL ON THE BACK OF THE BOARD. THIS IS PART OF THE LOCAL OSCILLATOR AND IS THE TUNING FOR THE RF OSCILLATOR. The goop around the coil is just wax, so it is soft. Don't use hot melt as the glue may have an effect on the tuning of the coil.
Don't ask me how I found this out.... it CAN be retuned, but you will need a scope and good soldering skills to solder a test point on pin 10 of the chip to monitor the RF limiter's output for tuning, and VERY small adjustments to the coil to bring it back. I was able to tweak the coil a little better, but I have some familiarity with RF and oscillators.
I can post some pics if anyone wishes.
I have more than trippled the control distance for these with this mod, and you can find TM751's in 4 pack on Ebay for around 4-5$ each.
You also get the antenna as a bonus for other mods!
It's a win win mod!!!
