Hi Eric,

If you are an Android user there is an app called DroidPSK that runs on any Android device.  It was done by Wolphi LLC  (www.wolphi.com).  He also has an interface that goes between the droid device and the radio.  I purchased on for my FT817 and have tested, but never used in the field.  It was nice to work you during our trip.

Karl,

Great idea!  I've been reluctant to try CW on a summit because of my poor CW skills.  I didn't want to face a machine gun pileup.  PSK via the paddles might be the best way to start.

Thank you!

Yes, I'm sorry I missed the email completely. The uBITX is a little inexpensive 160-10m easy to assemble kit with full CAT.  The computer interface makes it a perfect digital rig.

I day dream of getting out to POTAs. And l love to read about how folks do this stuff.

There's a definite art to working CW with a 2 kc bandwidth on receive. There were mods to add RIT, but with that bandwidth, you can't move from anybody, ya know?

Hello All,

I haven't been in the PSK waterfall much this last year because I have become gravely addicted to SOTA.  I keep thinking how much fun it would be to operate PSK on a mountain top.  The problem for me is all the extra gear I would probably need to carry to do that.  I know that some people use a smartphone to operate PSK but that's about the extent of my knowledge there.

Does anybody know of an ultra-lightweight way to operate PSK?

My pack currently runs 24-28 pounds on day trips so it would be great not to add to that too much.  ...or diminish the discretionary funds too much either.

Here's an excerpt from my QRZ page that explains a lot of what you see in the picture.  


Interpreting Solar Data

A” INDEX … 1-6 BEST 7-9 FAIR 11+ BAD - Represents overall geomagnetic condition of the ionosphere over a given 24 hour period.

“K” INDEX … 0 or 1 BEST … 2 OKAY .… 3+ BAD .…. 5 VERY BAD - This is the overall geomagnetic condition of the ionosphere averaged over the planet over the past 3 hours. K index indicates geomagnetic storms. Below 10 MHz, K of 5+ increases noise level appreciably, K of 7+ degrades HF significantly.

“SFI” … 70 NOT GOOD … 80 GOOD … 90 BETTER …100+ BEST - SFI is the Solar Flux Index and is a measure of total radio emissions from the sun.

  • Higher Solar Flux generally suggests better propagation on the 10, 12, 15, 17, & 20 Meter Bands. Solar Flux rarely affects the 30, 40, 60, 80, & 160
  • Generally, propagation conditions are best when the A index is 10 or lower, and the K index is 3 or lower.
  • SFI Solar Flux Index: When >70 then 20m opens. When > 90 then 15m opens.
  • X-Ray : Solar X-Ray emissions will cause shortwave fadeout. Classification from weak to strong X-Ray emissions : A, B, C, M, X
  • During a solar X-ray outburst, the lower frequencies are the first to suffer, with subsequent fading up the frequency spectrum over a short period (usually less than a hour). Signals crossing daylight paths will be the most affected (obviously as X-Rays come from the sun).
  • If you cannot hear signals there may be nothing wrong with your receiver or antenna. To see if a fadeout has occurred go to http://www.solarham.net/xray.htm
