PSAT2 coverage improves 10-22 June
PSAT2(NO-104) will enter about 2 weeks of good USA coverage between about 10 to 22 June. Normally its low inclination orbit favors the southern USA. But the orbit is also elliptical and so there are times when the elevation angle to more northern stations rises as much as 20 degrees.. Bringing higher latitude stations into the footprint..
Currently it's VHF Xponder has been in DTMF & APRS-to-Voice (A2V) mode but with the ISS digipeater being inactive, we will enable PSAT2 for normal APRS operations plus the A2V feature.
its HF/UHF transponder will remain in linear operation for PSK31 SSTV and Voice.
We also note that PSAT(NO84) has awakened from poor sun angles and we will try to activate its digipeater.

As noted below. We have enabled PSAT2 for APRS on 145.825 and it should be 4 times stronger than PSAT (+6 dB). Also it has the APRS-to-Voice enabled for your enjoyment.. See http://aprs.org/psat2.html for how to use the A2V feature..
We tried to enable PSAT digipeating but it died. a day later. We will keep an eye on it and enable it again if it becomes stable. Bob, WB4APR

Bob How about NO-103 digipeater ? I remember we tried to turn ON, but no success. Do you want to try again ?

Its here! PSAT2 (NO-104) is entering a great operating period for 10 to 22 June in the northern hemisphere. Passes are late evening but moving earlier.
As noted below. We have enabled PSAT2 for APRS on 145.825 and it should be 4 times stronger than PSAT (+6 dB). Also it has the APRS-to-Voice enabled for your enjoyment.. See http://aprs.org/psat2.html for how to use the A2V feature..
Also we have enabled PSAT (NO84) digipeating.

NO-84 has very few live ops beaconing lately, but it had a nice signal the last few passes.
NO-104 was good tonight, but I was not able to decode packets or get digipeated, the voice downlink mode was pretty clear.
The APRS birds are very enjoyable (without the QRM of voice).
