I look forward to that, it is the best way to test the new H rx, to see if the strange noise floor seen in the old rx has gone. PS Having some last minute problems with the new rx: the PSU does not start reliably when fed via a long cable. Had this problem with the E rx and it appeared to be the reservoir caps too high. Now I discover the cause is the resistance of the cable. Just ordered 48V to 12V DC/DC converters and a 48V power supply, hopefully that will be less sensitive to the cable resistance. Next day delivery but it wont arrive in time to use it tomorrow. I'll have to improvise something out of the junk box! PPS A test run today - managed to avoid The Grendel with a carefully timed sausage and got through the farm yard without being bitten! Not thinking ahead, I'd only taken one sausage with me. You can guess what happened on the return trip. -- Paul Nicholson --
