just be careful as there are two different chipsets ! theres a low powered version..
Would it be possible to use the HPnD in the controller and the HnD in the bird? Understanding the connections are different and may need to mod the HPnD.

Based on what we can see in the config files, Solo and the controller may be limiting these cards to a maximum of 500mW output. This isn't confirmed through testing, but it would mean the extra effort to fit the 1000mW card might be more trouble than it's worth.Would it be possible to use the HPnD in the controller and the HnD in the bird?

I was told the 800mw MicroTik cards work at 800mw out of the box with Solo. No config changes needed. Just remove them on updates, but bitcoins be good to get derisive confirmation of that.Based on what we can see in the config files, Solo and the controller may be limiting these cards to a maximum of 500mW output.

Do you only fly alone? If not, the higher power transmit will make it more likely your flying companions will have a harder time flying with you.
I have only swapped out my controller card so far and with just one ALFA antenna, I've gotten much better consistency and range already. Combined with the hostapd.conf edits, I've already got more range than I need for line of sight in a very dense urban area.
Unfortunately, my gimbal needs to be RMA'd so I'll wait until it's all settled before I modify my Solo wifi card and antenna. I'm now more after wide coverage and consistent video streaming with minimal aiming, since 4000ft+ is plenty far for LOS flying.

I haven't found they are needed after I made the config.apd changes that open up all the WiFi channels allowing Solo to choose the least used, and got an FPVLR V1 antenna.
People that swapped them though, get the expected improvements in distance (average 1.2 miles) with stock antennas, which would be consistent with 800mw.
I asked @NYG if it works, but no reply?Yup it would be nice to have some confirmation on the configuration/wifi card output power limits but I admit I haven't been pursuing it.
On this site, @NYG posted here that the stock cards are only 21dBm
WiFi Card upgrade testing
@NYG also posted this :
WiFi Card upgrade testing
power=`cat /sys/kernel/debug/ieee80211/phy0/power` <- The output of this is 30
if [ $power -gt 27 ]; then power=27; fi
echo "$power"
return 0
}
Which appears to be logic to limit the card to 27dBm (500mW).
Have you seen others who have posted results on the output power? Would be nice to see.
I don't think he's been pursuing it either. I think the current range increases have been enough.
Yes I can understand that and appreciate it but, why would somebody put that up without at least testing it to see if it does work or not? I would try it, if I had the new WiFi cards.I don't think he's been pursuing it either. I think the current range increases have been enough.![]()

I haven't pursued it either, and for the same resons... No need.... I do know though that many on the Solo Mod FB group have, and they are getting measured improvements from the stock cards, so with all those data points, something almost has to be different.I hadn't pursued the output power question any further. I have no way to really know if the commands are doing what's expected or any real way to measure.
Early on with a linux laptop I tried increasing the power of a stock card. The commands would take as if they worked, but an iwconfig always showed the card with a TX-Power of 21dBm.
Also the code on the Solo is just BS to list TX-Power.
I have the regulatory domain patched on the drivers and have been using WiFi channel 13. That along with whatever power the cards are operating at has worked really well so I've been content with what I have.
In the sololink_config file this is the function they have to set TX-Power:
set_wifi_power() {
desiredPower="${1}"
if [[ $desiredPower =~ ^-?[0-9]+$ ]]; then
if [[ "$desiredPower" -lt 0 || "$desiredPower" -gt 27 ]]; then
echo "error: wifi power level must be between 0 and 27"
return 1
fi
else
echo "error: attempting to set wifi power to non-integer"
return 1
fi
echo "$desiredPower"
iw phy0 set txpower fixed $((desiredPower*100))
return 0
}
That function restricts power to a max of 27dBm.
In the end though it's just executing this "iw phy0 set txpower fixed $((desiredPower*100))"
So if you wanted to set a TX-Power of 28dBm you would execute:
iw phy0 set txpower fixed 2800
Didn't know what was involved in determining power out put.I am assuming you mean testing these config files and posting the exact power output?
I don't think we have the equipment to measure the signal strength coming from the cards. My friend in Asia has a metre that you connect to the transmitter. But I definitely don't have one. Makes testing difficult. Also, modifying the config files to test does come with some risk. Other times I'm sick of tinkering and I just want to go fly and get some good video while the weather is still goodNow if my darn gimbal didn't need to be RMA'd!....
@NYG reported what he could get out using command line and what he could find in the config files.
The MikroTik cards are rated on their spec sheet to output max 29dBm (800mW). Mind you this is at a particular data rate (typical), not across the entire usage range of the card.
We also know there are regulatory restrictions on wireless output depending on region - hence it's safe to assume that 3DR has put programming in place to ensure compliance when shipping internationally. We just haven't been able to confirm when and, using which files this programming is in effect.
Most of us are here like you - sharing information online while playing with our hobby - with varying levels of tech ability. The cards work for most people, we just might not be able to explain every part of it.
Only you can decide if that's good enough to invest $40 (X2)? I can definitely say that regardless of wifi card or antenna mod - your results will vary based on your location and usage and you will need to find out what works for you.
So guys, if you were to do one wi-fi mod, what would you think is the most effective one?
