Deviation output power 150mW = 100mW

Nice to know, still wondering where the 60mW setting ..disappeared .....

Ok, but what is it at the 100mW setting?

..thats's for your 8s, right?
Would be interesting to collect results for some other TX.

Please Seyby, would you please take your ImmersionRC RF Power Meter and do this with your Devo 10 and on the 7e for the NRF?

Basically you are right, but it may vary on technical shape.
.... 65mW is not bad at all considering the FrSky DHT (DJT&DFT) modules you can buy for different TX, are even 60mW.
But we should stop comparing the Devo with the Spektrum TX, especially the US version, as they can have up to 230mW.

just my 2c..

EDIT:
EUROPE Version...

Sorry for the off topic guys.
I have an old Spektrum DX7 bought some years ago imported from a small Hobby shop in the States.
In theory, my DX7 is a USA version, but the FCC ID is not the latest with 300mw power output.





Anyone could explain me what's the power output from my DX7?

Sorry for the off topic guys

Thanks PB
Strange power output. Not the USA version power output (300mw) but not EU version (about 100mw)
I guess this radio probably was version 1 or something similar

Could anyone measure the power output on Devo 10 (black)?

Update: Cesco2 seems so:
www.deviationtx.com/forum/3-feedback-que...=none&start=60#29784

Cesco2 values are different:
"Devo 12: Output power is 85mw on the 150mw setting (immersionrc meter) and surface range is around 250m with dsm2 or dsmx setting, 7 channels, no telemetry.
The Devo10 has 60mw output, 150mw setting, dsm2, 7 channel."

vs Vlad_vy:
Devo 8s 150mW = 65.21mW = 18.00dBm
Devo 12s 150mW = 74.38mW = 18.71dBm


I believe my Spektrum DX8 had ~18.x dBm (below <20dbm) written on the HF module label when I had opened it.

How does the 100mw/150mw setting work in the DeviationTX HF module code?
Where does this labeling texts come from originally?

If "150mw setting" != 150mw/>20dbm real output power, isn't there any way to CORRECT the labeling within the firmware?
You know about EU/DE regulations, ETSI 1.8.1, declaration of conformity for FHSS & stuff and max 100mw/20dbm output power.


Why do you even want to give the people talking negative about DeviationTX another additional argument for labeling settings "150mw" when it is not that output power in reality?

I can remember one older thread where it was asked if you maybe could simply remove the "150mw" setting at all for "a more compliant EU" DeviationTX version Well, forget about this with newer ETSI 1.8.1/1.9.1 FHSS class regulations...

It would be interesting to have also for Devo 7E and Devo 10.
Thank you for your help.

Hello,
I just thank you for all the valuable information that helps me a lot. I think I'll resolder the module output to put an RG178 coax with SMA connector to place the antenna outside of TX. I also saw that the Devos Devention were Walkera, in fact I thought Devention was a trademark.
BTW my new antenna is 2DB and the older is <3 DB, do you think it will go?
Thanks again.

@Mod: Please make this thread STICKY (always on top)

Interesting; the RF summary says the 6, with a 0dbi antenna, has a peak power of 14.5dbm, while with 3dbi antennas the 8s and 10 give 18.2 and 19.31 respectively.
No idea what that translates to, but seems to show a good case for swapping in a gained antenna if you are using a 6/6s.

Though also of interest is in the internal photos, which unsolder the shield of the modules, both the 8s and 10 are shown with black modules? And it seems from a brief comparison that the module shown for the 6 has three additional capacitors, which are left onpopulated on the ones shown for the 10 and 8s?
