This is a great explanation on how to set up these call outs and what values to use. EdgeTX / OpenTX use RQly for the "Signal low" call-out on the telemetry page, but I love your idea of having the value read. Someone should add a checkbox for that feature! The reason the RSSI doesn't go all the way down is usually due to the receiver's amplifier adding 12-15dBm, so -112 will drop off at -100 roughly.
Some feedback: My setup is a TX12 with EdgeTX, a Happymodel 1-watt ELRS module with V3.3, and a HM Mob8 analog with an ELRS SPI receiver with V3.0. I'm running the ELRS dynamic power limit at 500mW. I set the TPWR callout interval to 50 mW; when set to 1mW, it gave me constant callouts. Most of my flying uses less than 100mW output, so I wanted Betty [my TX12] to pipe down and only tell me when I'm over that. EDIT: I added a logical switch that is set to ON when my throttle timer is more than 15 seconds. ANDing this logical switch to my TPWR and link quality logical switches makes it so I get an accurate countdown for landing without a callout stepping in.
I seem to remember hearing about the 0 for 50mW issue awhile ago. Not sure but think it may have something to do with the CRSF protocol and that the TBS protocols don’t have 50mW so the CRSF protocol doesn’t support that value.
@uav Tech from elrs site: OpenTX has no value for 50mW in the CRSF Telemetry protocol and instead will be read as 0mW. EdgeTX versions 2.5.0 and newer have the proper 50mW readout. Thanks for this video!
Very useful detailed explanations! Now have my long range 3S powered quadcopter telling me every 10 seconds what the battery voltage is once it drops below 12v. Much more comforting than just playing a track telling me I have "Low Battery". Interesting to hear the voltage recover when I ease off on the throttle. Thank you!
Nice. Compared to my first 'real' TX unit, a 2-channel Cox-Sanwa from the late '70s, today's boxes do everything but make you a sammich. I got my AG01 Mini-equipped RM TX12 made into a proper Bitchin' Betty - and now I got 2 more callouts! Giddy-up. . .
Really cool inside stuff! Thank you very much for sharing! I'm still trying to figure out at which number to set up the warnings for my 250mW/250hz controller.
which awarning? Range? I would set that off -dB. Anything lower than -95dB for me. That way, you have a buffer. You will see packet loss starts to drop after lower than -95dB. Its jumping up in power is the first indicator you are starting to put on some range. Then when you are at max power and you get a dB warning, you know you are near the end of the rope.
@@uavtech Hi, sorry for the late response and thank you very much for your answer. I had been researching and found the "take 10 off from the number which is shown on your rc next to your hz number" answers. I thought I had seen some kind of table for this with the different types of dB and hz. I didn't realize it's so simple... Thanks to you too for mentioning this! Took me so so long and now I can enter the correct warning number at BF and not worrying too much (yes, I know and use RSSIdb and l:c). Have a great day, sir! Btw.: I don't have these sources for the logical switches. I have different ones, but nothing fitting into this.
Awesome video! Quick question, when i try creating the logical switch, in the v1 row, TPWR, and all the Rqly and rx and tx related items are not there, do i have to enable something somewhere?
Great tips! I've got mine set to read out power levels at >51, because my dynamic power often goes from 25 to 50 to 100 with the rf noise around my house, but if it goes from 100 to 250 or 250 to 500 it reads it out to me. So maybe mine also reads 50 as 0 but I never hear it.
Hi Mark, another amazing tutorial. Thank you so much! So, basically your screen at 2:17, for say 5" quad, light HD freestyle mostly, do we need all those L05, L06, L07, L08 and L10 except maybe that L06 as you mentioned you'll probably get rid of it? I've set my L07 as 70% instead of 50%. Everything else should be as in that screen that shows up at 2:17 sec mark into your video? I use 250Hz (-108dB), so I've set my L05 as a
I run 250 always not sure why I would run any less. I suppose if I could go higher. It would always run higher. Buy an alarm on low db is something I should set up
OpenTX has no value for 50mW in the CRSF Telemetry protocol and instead will be read as 0mW. EdgeTX versions 2.5.0 and newer have the proper 50mW readout.
I may have missed something. Do I need to have a quad plugged in? When I go to special functions after doing the logical switch, the TPWR option isn’t there. Sorry, new to ELRS, coming from CRSF where dynamic power was a no no.
if your receiver powers up when you plug the FC into USB, you should be good. Clear and Discover Sensor again maybe. TPWR should also just be coming from the transmitter module.
@@uavtechThat worked. And very cool! Stuck a quad in the washing machine and walked across the house. After 2 brick walls and the washing machine it started doing the callout. Gotta love elrs for working from in a “faraday cage”. Thank you for all you do!
Yes. There is a transmit power OSD element in the latest versions of BetaFlight. On ExpressLRS though you need to make sure you are using wide channels if you want the value sent from the module to the receiver.
@@ivanmojica9924 ELRS has option for more efficient channels (hybrid). This limits some channels to only a few possible values. Wide channels support more possible values except on aux 1 that only does on/off values for arming. Go to the module settings on LUA script or module screen if available. There will be a channel mode option that can be set to wide.

Thanks for all your help! I don't fly a lot of long range but still like setting this up. Appreciate your time and all you do for the community.

Would be interested in a video for TBS.
That was very helpful to see you go through the setup. Thank you!

Very helpful. I fly FPV without an FC or osd
and who is really looking at this stuff in the osd too while flying.
I run 250 always not sure why I would run any less. I suppose if I could go higher. It would always run higher. Buy an alarm on low db is something I should set up
Incredible!
Any chance you can do a walk through of the modula 6 2024 set up?
Hello UAV Tech,
thanks for your video. I already have done a similar setup on my Radiomaster Boxer with 1RSS

Jumper T20 does not have any of these functions you are showing :), neither does my zorro.

can you do one for crossfire?
shpuld be the same. same protocol and RF tech.
I would need to look. I assume it reports TPWR. I know it reports LQ.
@@uavtech how about the thresholds? Also the same?
Is there a way to set it up on your OSD your mw power
Yes. There is a transmit power OSD element in the latest versions of BetaFlight. On ExpressLRS though you need to make sure you are using wide channels if you want the value sent from the module to the receiver.
I'm very new to E LRS I did activate it on my OSD but did not read I would love to get to work and what is wide channel sorry
