+The Hope FM Mfg product page, with links to application notes is: [[http://www.hoperf.com/rf/fsk/RFM22B.htm|here]]  Pinout Diagrams are on page 61.
 Note Frequency range legally available is 434.04MHz - 434.79MHz according to IR2030.
+Now using radio1.write(0x73,0x03); // High and radio1.write(0x73,0x00); // Low in rtty_txbit, gives a much tighter signal.  Detailed here: http://ava.upuaut.net/?p=408 Thanks to Dave Akerman suggested (as recommended by Navrac)

+===== Testing =====
+In the warm office, Signal rx'ed loud and clear on 434.190.700 Mhz rather than the set 434.201 Mhz

+Sentence is: $$PROM,2,000010,0.000000,0.000000,0,0,25,42*63B0

+===== Habhub Payload Config =====
+Using the form [[http://habitat.habhub.org/genpayload/|here]] I generated a payload config:
+Payload Name: G7PMO $$PROM
+Primary, 434.175, USB, RTTY, 480, ASCII-7, 50 Baud, Parity none, 2 Stop bits.
+{"type":"payload_configuration","name":"G7PMO $$PROM","time_created":"2012-11-18T22:25:32+00:00","metadata":{"description":"G7PMO's ProMini Tracker"},"transmissions":[{"frequency":434201000,"modulation":"RTTY","mode":"USB","encoding":"ASCII-7","parity":"none","stop":2,"shift":480,"baud":50,"description":"Primary"}],"sentences":[{"protocol":"UKHAS","callsign":"PROM","checksum":"crc16-ccitt","fields":[{"name":"sentence_id","sensor":"base.ascii_int"},{"name":"time","sensor":"stdtelem.time"},{"name":"latitude","sensor":"stdtelem.coordinate","format":"dd.dddd"},{"name":"longitude","sensor":"stdtelem.coordinate","format":"dd.dddd"},{"name":"altitude","sensor":"base.ascii_int"},{"name":"satellites","sensor":"base.ascii_int"},{"name":"battery","sensor":"base.ascii_int"},{"name":"temperature_internal","sensor":"base.ascii_int"}],"filters":{"post":[{"filter":"common.numeric_scale","factor":0.001,"round":3,"source":"battery","type":"normal"},{"filter":"common.invalid_gps_lock","ok":[4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20],"source":"satellites","type":"normal"}]},"description":"$$ProM Std format"}]}
+Doc ID: 7ca1c7874831f6e8a0616ca98add1600
+Note the filter I use to identify if I have a satellite fix "{"filter":"common.invalid_gps_lock","type":"normal","ok":[4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20],"source":"satellites"}"
+I should really implement another variable in the sentence to define lock directly for the PUBX code, but I am told the above should do what I want it to do.
