Hello all, I tryed out the pass on APRS about 12:50 UTC today. Very very strong satellite 57! Could not digepeat a packet for some reason. I think i was a little confused about the paths, what are the paths for to and via? Im using UISS. Got many frames of Telemetry this pass as well! Also bob you should at PSAT to oscar.dcarr for recepetion reports. I noticed very few people got digpeated... Also bob the frames that have all the numbers in them, what do they mean, are the just noisy tlm frames? Also for all the people out that wanted to know what their frame of telemetry means here you go:
PSAT Beacon specification:
CALL beacon MODE NOF DET AGC VC IC TMP
Where: CALLidentification of the beacon (callsign)beaconkeyword indicating beginning of dataMODEA or B (A – transmitter always on, B – transmitter turns on, if BPSK31 signal is present)NOFnumber of frame (0 … 999)DETpercentage of BPSK31 detection (0 … 99%)AGCpercentage of AGC operation (0 … 99%)VCsupply voltage (10 mVolts)ICpower amplifier current (mAmps)TMPtemperature of PA transistor (deg C)
The AGC measured voltage is highly nonlinearly dependent on the input signal, morover the limiting values of measurement vary with temperature of the chip and its supply voltage. Indicative only conversion equation was computed as from 50Ohm generator to input of receiver Pin = 0.472xAGC-113.5 [dBm, %]
Example:
W3ADO-5 beacon B 044 03 24 540 198 +28
It means mode B active, frame number 044, BPSK31 03 %, AGC acting 24%, supply voltage 5.40V, PA current 198mA ant temperature of the PA transistor of +28°C. Fm PSAT To APRSON Via ARISS <UI pid=F0 Len=52 >[08:47:54] s#018259,0z200,jkIjkHjkGjkFikFikDikAhkahkbgkbgkcgkd
