I've been reading up on propagation and looked up a near real time map of f0F2 and guessed I should try a kiwi SDR in Hawaii.

 There was DW with a pretty nice signal whooping away.

Before sunrise the BAT reading was 12.8 and PV was zero. DW seems to quickly recharge the battery starting around sunrise and finishing within a couple of hours

BAT  13.8
O TMP   61
I TMP   61
PV  796

The three digit PV numbers are puzzling!

I noticed listening last night that the last whoop before telemetry is now more of a long dit than the normal whoop.  Was that just an anomaly of yesterday?

Hi Syfr!

I've been logging the telemetry from DW for a while now and here is what I have observed.

Most of the day the BAT reading sits at 13.7 with the PV reading a single 4 which is about what a typical PV controller might consume in milliamps while not charging the battery. Once in a while I will catch a three to 4 digit reading as if the charge controller is topping off the battery. Somewhere after 3 PM the BAT reading ramps up to 14.3 (equalization volts) and the PV reading is in the 400 to 600 range. After sunset the BAT reading slowly declines until it hits 12.8 prior to sunrise. During that time the PV reading is 0 although once in a while it reports a 1 (A2D noise I guess). Around sunrise (06:30-ish) the PV reading starts at a couple of digits and as it ramps up so does the BAT reading. Around 07:45 I see the PV reading peak in the 1100 to 1200 range. Within an hour after that it is reading 4 or 5 with the BAT reading sitting at 13.7 or 13.8. Am guessing a couple of amp hours were sent back into the battery so the panel and battery are not small.

I'm convinced PV is reading out in milliamps and correlates well with the BAT readings.

I believe it has always been about 2/3 of an upward sweeping whoop. Am guessing it is just a matter of timing as to when the microcontroller decides it needs to send Morse Code rather than analog whoops.

Thanks for sharing your observations on the PV telemetry.  I normally don't listen early in the morning as I have the opportunity to  this week, and the sun availability vs PV number correlates well to what you describe. 

I've noticed also, that the battery is pretty stout (especially given the duty cycle of the transmitter) and its recovery time is short, which supports your observation on the capacity of both. It's a well designed system and hopefully will be with us a good long time.

Wish we could send out the Geek Squad to service Windy.

  I had never noticed that last slash before telemetry as being truncated as I heard it yesterday. Perhaps the AGC of whatever radio I was using further shortened it to the "dit" I heard

One of the other nice things about DW is the excellent frequency stability despite today's higher temperatures.

Listened to DW last nite and could hear it inside on the whip  antenna on the portable. Really impressive performance for a very marginal receiver.

Windy appears here earlier and disappears earlier than the whooper.
