DF36 cuts out at distance?????

[kevinpratt823]

Well, the signal booster didn't help, and I found my UL-1 doing it a bit also. I think I just notice it more with the DF because I go farther away with it. Aso tried some different timing settings, in case it was a cogging issue, nope. I am beginning to think that this pond just has some Bermuda Triangle like holes in the space time continuim.

You bet! Bermuda Triangle is every where! I had encountered it on land as well, an empty dirt lot and all of a sudden a lost of signal. Happened in the pond with my MHZ Lizard Xtreme's maiden, using Spektrum MR 3000, the hull has no CF, antenna spread apart inside the hull like my DF 26. One particular spot and the boat was dead on water. Later I taped one antenna underneath the hatch, seemed better but I wasn't willing to go to that corner any more. Thank God for Throttle Fail Safe!

Has anybody found the MR3000 to hold a better signal than he MR200, or is it just "better" because of the additional ports and telemetry?

Our pond has one spot that kills the signal, doesn't matter what brand of radio, AM,FM,2.4 all do it. Has done it for years in the same spot. Luckily it's not in a part where anybody should be driving a boat, walk around the shore and you pick up the signal again.
Not sure if it's a line of sight thing or what, but you really can't see your boats well from the driving area due to trees and the slight curve of the shoreline.
BTW non of the marine rx's from Spektrum have telemetry, only the SR300 as far as surface telemetry. I prefer the MR300 receivers simply because they are encased in plastic, just a solid block, very water resistant. I have one MR200 and see no difference in range. The one thing is my MR200 does not like a mix of digital and analog servos, the analog one will jitter and hunt for centre for some reason, use two digital or analog servos and everything is fine. Oddly it seems to be the worst when I use any of my JR analog servos. I can use an esc and any kind of servo together no problem.
That signal line booster will not help you in this instance, all it does is increase the signal voltage coming from your rx to the servo, it does nothing to the actual current being supplied or used by the actual rx or servo, it only boosts the signal going through the odd (orange, yellow etc)coloured wire, not the positive or negative. Lots of info out there about what they really do, they do not go between the bec or battery and RX, they will do nothing there as it doesn't boost that voltage at all.
The signal voltage is about 2.5V while you still have full voltage (6v) going through the +&- to actually power the servo. All it does is boost that 2.5v nothing else. Will not increase the operating voltage going to the RX or servo. Will not improve your range or reception, not designed for that.
Like I said plenty of info on other forums about these boosters, along with O'scope traces to show what it is really for.
They are designed to help devices that do not like the low 2.5 signal voltage, thats all.

Good info Husky, thanks.

Try to get at least one of your antenna wires outside the hull. I had problems on my boats with 2.4GHz until I used an outside antenna tube.

The long one is up about 8" in an antenna tube, I may even do a second short tube for the other........

Ideally you want the antenna wires at 90 degrees to each other, so one coming up out off the boat & the other running along or across the hull.
