No, still the V1 software. I'll try the V2 software as soon as I can make up a suitable lead, but if my fault diagnosis is correct (RFI) then I don't think V2 will cure my servo chatter. It'll be fun to find out.

The response looks remarkably similar to the 'coggy' response (at moderate stick movement speeds) I had with some servos using the FrSky telemetry units on my Futaba Tx.
Good question, I'll check it out. It'll be a good servo to try with the V2 software too.

"RX must have a RS232 converter installed between the RX module data pins and the PC comm. Port."
Is it enough to make a connector that converts the connector from the FrSky usb cable to a 3-pin connector to use with the Rx?
Or do we need some sort of level converter?
Check out the thread "How to update FrSky receivers" for more details on this, including a link from Mr. Sneezy to a suitable converter board on eBay.
Basically it needs an inverting level shifter to make the connection. RS232 signal levels swing between +ve and -ve voltages (the FrSky USB cable outputs +/-6V for example - other converters give up to +/-12V), but the FrSky Rx only takes logic level signals (0 - 3.3V). Also the Rx needs an inverted signal stream (0->1, 1->0), so the converter also has to invert the RS232 signal.
