I would just like to say a big thank you to mike G6 TUH for all the help he has offered me over the last week in setting up ham radio deluxe now enabling me to now work the data mode portion of the amatuer bands many thanks mike from what was a very frustratrd operator all the best. Dave M3XIE

Pleasure Dave to see you now ‘cooking’ on PSK etc. 8)and hope you catch lots of SOTA activators with the extra string to your bow.
Best wishes
Mike G6TUH
Glad to hear you’re up and running Dave. I suppose you’ll be wanting a PSK31 SOTA activation to chase now won’t you? I may be out later to provide this. Keep an eye on the alerts/spots.

Tom, how are you finding the battery life of the S3 while running PSK?
I rigged up a USB connection for my SLAB some time ago, but have hardly used it since aquiring the S3. My old HTC phone had very poor battery life.

No problems. Probably makes me need to charge it up after 1.5 days instead of 2.5 days if I use it on a long PSK activation.

In reply to M1EYP:
The European S3 has a quad core 1.4GHz Cortex-A9 cpu and no floating point support IIRC. If your PSK app uses floating point maths (easy to write the app) then it will use a lot more CPU power than a US S3 would. The US phone uses a dual core 1.7GHz Qualcomm 8960 which has Qualcomm’s Krait CPUs. You get a lot more bang per Hz with a Krait than an A9 even though it’s the same instruction set. So 2x 1.7GHz Krait will have the same “oomph” as 4x 1.4GHz A9 CPUS but at less consumption. Also the Kraits do have hardware floating point. That would reduce the number of CPU instructions executed so should reduce power usage.
Battery life should be better running this kind of app on a US phone than an Eu version all things being equal. But they’re not, so it’s probably the same!
The thing to remember ('coz it’s thumped into me by my job all the time) is that all phones are designed to sit asleep and occasionally poll the network or respond to a poll. That’s how you make the battery last, by never using it. Running any kind of application that keeps on going and has the backlight is a sure-fire way to make you seek out a charger.
