FrSky Module Hack


Hi!

Just finished hacking my RD 6000 Super with the FrSky V8HT 2.4 Ghz Module. After some research on RCGroups and other places I decided to use a switch for the power to the module since I could not find any information to power off the RF section without taking out the crystal or going through the trainer port. I didn't want to use the trainer port so I decided to just take out the crystal each time I want to use the 2.4.

I don't have any extra FrSky receivers to do a range check. I have some on order and will use them with the new setup. I plan on using the 2.4 system mostly for DLG since the transmitter is nice and light with a LiFe battery and does most of want I want for mixing.

I'll let the pics take it from here.

Problem with my installation


I just installed the DIYmoudleV8HT in my RD6000 following your pictures with the only change being that I put a servo connector in the wires going to the transmitter (gnd, v+ and PPM signal).

I have a problem. Though I can bind the transmitter and the receiver (V8R7) with no problem, it's that no other signal gets to the receiver, there is no servo movement unless I remove the RD6000's antenna.

Do you have to remove the RD6000 antenna to get yours to work? I'm kind of concerned that running it like this will overload then 72mhz transmitter and burn it out.

If the 72MHz part still powered?
Shouldn't... at least to save battery, is not other isues, as you described.

How do you remove power from the 72MHz section?

IMHO: I would lose the big toggle switch to change from one to the other. It's not like rates or retracts and your going to need to switch it in mid-flight. Personally I would want the switch recessed and as difficult (nearly imposable) to accidentally change as possible. If you have to open up the unit to removed the crystal then the external switch would only serve to accidentally knock yourself out of the air.

Most radios of this class have clearly divided the mainboard in two blocks (the red line)
Left side is the "brain" that handle sticks, switches, display, and finally produce a single output, the PPM.
Right side is the RF block, that transmit to the antenna the signal.
If you watch along the red line, there are only 3 tracks the cross it.
One is PPM, already identified by you.
One of the other two should be the power for RF block, I drawed green circles where to check.
If the area in yellow elipse is the power switch, then you must check what PCB track comes from that area to the right side, crossing the red line, it's also a hint that it's a power line.

Another solution. Sell RD6000 and buy RDS8000 2.4 which is not so expensive radio.

In countryside, 72MHz is still used. You will find a buyer.

Is this conversion still possible? I have an old RD6000 collecting dust and thought this would be a useful way to bring it back to life. I did some searching for the hack module and seems it is discontinued?

The one way is discontinued, the two way still on sale.

Thanks for the quick reply. So this is a total noob question but what is the difference in the one and two way? The addition of telemetry?
