New whooper beacon on 4095.65
Teotwaki:
Easy armchair copy her at home tonight. No ear strain!
BAT 13.1
oTMP 94
iTMP 99 (interesting, only 5 degrees above ambient)
PV 1 (it's dark out there
Teotwaki:
A bit noisy here at home and also on KFS SE
BAT 13.1
oTMP 103
iTMP 106 (interesting, only 3 degrees above ambient)
PV 2
Charlie_Dont_Surf:
It looks like the battery voltage is dipping from the immediately preceding logs, taken at roughly the same time of the evening and an earlier sunset now.
08/23/2022, 0400 UTC, 4095.6 KHz carrier frequency, received on the KPH kiwi SDR, Point Reyes, CA, SINPO 25232.
BAT 12.1 (V)
OTMP 100 (F; still hot in the desert well after dark. Also perhaps the sensor is not in the open air.)
ITMP 107 (F)
PV 1

They state the otmp readings are from an outdoor sensor and the battery has a low volts disconnect. In all of my logs I’ve never seen the voltage below 12.8 and given my own weak skills with Morse a very low appearing reading was more likely to have been 13.1 rather than 12.1 volts.
I cross check temps by looking across temps in desert towns as well as seeing that DW’s two readings usually have a 3 to 7 degree delta based on time of day. A year ago I saw the iTMP hit 120 degrees.
Charlie_Dont_Surf:
Yeah, the signal was fading up and down last night and maybe I copied the battery voltage incorrectly.
Here is a recording of much better reception on the KPH SE beam kiwi SDR at 2230 UTC 23 August 2022 in the afternoon sun.

In any case, it sounds like the battery voltage is up to 14.3 Volts right now with the sun at "full gas".
