I have done that same shielding on the inside of my guitar bodies to reduce EMI getting to the pickups. Jumper should consider a spray on coating if that solves the problem.

I used some 3M 1245 tape specifically designed for EMI shielding. https://www.3m.com/3M/en_US/company-...4857497&rt=rud Look close and you can see I soldered a wire next to the ground pin at the battery connector, and the other end is soldered to a bit of the copper tape that covers one of the posts, so it grounds the back cover when it's assembled.
Here is a cheaper (Option) copper foil tape that I have used in the past with great success. https://www.amazon.com/gp/product/B0...ASBR1GKG&psc=1

I ordered the same tape from Mouser but haven't received it yet. Lol you beat me.

I figured that shielding the back-case would make a difference. Looking forward to seeing your followup video!

I didn't realize the 3M stuff is that expensive, I didn't buy it... lol It was left over from another project. I seem to remember the roll I have not costing that much though. I'm sure the cheaper stuff will work just fine, I'd at least try it before spending a much of money on the expensive one.

It shoud be okay even a cheap Aluminium tape. It is used frequently to EMI shild for some electric products. To connect to GND of Tx, Attach small copper tape that soldered some wire.

Hi,
I am a bit confused with Frsky's ACCESS protocol.
Is R9M module with ACCESS-FLEX firmware gonna work with current T16 nightlies, or will it work in the future at all?
I don't see R9FLEX option for external module in T16 menus fw 2.3.3N54.

Waiting for the next clear day
FrSky will make it very hard for the Jumper to work with any Access receiver. I won't say impossible, but who knows. I know that they implemented encrypted comms between the radio and receiver. I beleive this is in an attempt to stop Jumper (and others like them) from using the Access protocol.

I did that copper tape application on mine before hoping to resolve my Dragonlink telemetry range issues. Perhaps that's why I never saw the radio have issues. Even with that and the bigger bypass capacitor, I still get about a 30% reduction in telemetry range though.

I'd love to see some Dragonlink telemetry range tests with the newer T16 mainboard with more bypass capacitors.

A jumper pro multi module flash question.
I have a ftdi programmer with the option of 3.3v or 5v. However from the way I see the 5 pin connector wires (white and green) connected, I donít see any mention of the voltage on the programmer.
Can someone clarify if voltage is a problem or handled with the 2 wires connected together? Thanks

I don't have CP2102 or FDTI adapter here, but i used to flash miniosd via flight controller betaflight serial passthrough, can i used that same method to flash internal multimodule?
The only things I afraid is all the tutorial warning to use adapter at 3.3v, with the FC I can't not confirm this.

I think you can just power the module by turning on the transmitter and connect the ground wire from your flasher but not the power. Don't know if you can flash through the FC. Does it show up as a comm port on your computer?

Yes, it's betaflight serial passthrough.
But to advoid the risk, i just order a CP2102 adapter for peace of mind.

On the up side I can leave my R9M installed in the Jumper now vs swapping between R9M and DL. I'll see how I like the repeater setup. Maybe even do the copper taping thing anyway...just in case.
