I have been planning for a while to do a “multi mode challenge” during one of my summit camps…CW SSB, FM, DV, SSTV and FT8. So today i played with my QMX+ to see if i could run FT8 from an android ‘phone.
I was amazed to find that connecting a usbc cable from ‘phone to QMX, using the Android app FT8TW (available in the standard Android app store) i could easily run FT8. See picture.
FT8TW is brilliant…auto logging to qrz, mapping of contacts and an excellent spectrum display.
Using the same direct usbc connection i have also successfully sent and received SSTV using DroidSSTV.
It all looks hopeful for a multi mode activation. I just wanted to share this as I am surprised how well the QMX works when connected to a mobile phone
The picture shows the system running on a very cheap (less than GBP100) Android tablet, so i could use my phone to take the photo
My phone is an inexpensive Ulephone Armor…so nothing special
Well that didn’t go as hoped…i am writing this from inside ny tent on Seatallan G/LD-025. I have just had a session of FT8, using my android phone connected to my QMX
I made about 6 contacts and then the BS170 transistors failed in the QMX. I had an SWR of about 2 from my EFHW on 15m…so probably my fault.
Could have been worse, for a couple of mins after blowing the finals the QMX refused to power on…I’m guessing it has some sort of temperature sense.
Stocking to CW in future.
Bag of transistors already on order from CPC, and now i am making a hot chocolate to commiserate. At least i still have a couple of 2m radios with me for the rest of the night.
One of the BS170 transistors was already dead when my kit arrived. I ordered a batch of replacements; they’re slightly larger than the originals, but they work perfectly.
