As well QRV sometimes /Mobile HF Robust Packet & FSK300: F1MHV & F1MHV-11

I don't have paper QSL card, and i will not have any: QSO confirmation only via qrz.com logbook and electronic QSL only via www.eqsl.cc for the time being, thank you for your understanding.

Address shown on above eQSL card sample is not valid anymore!!

When doing SSB voice, most of the time i am operating following QRGs +/- QRM:

28430 / 24965 / 21265/ 18165 / 14325 / 7185 USB / 3791 USB and a French net on 14122, but check as well PH9HB/AM recommended ones, i might be there as well (or in the near) wink

Yes, on 40 & 80m operating USB, no other choice in /AM ( http://hfpack.com/air/ ).

Updated informations (ATC flight numbers and expected "on air" times) via twitter.com -> DF1CHB

Please find bellow some pictures and few informations about onboard HF equippment:

- Old style control panel, found in 737-300 series cockpits, on some aircraft LSB operational, some not. 1 Khz step.

- 90's style HF control panel found in 737-700 cockpit, 1 Khz step, no more LSB.

- New generation HF control panel found in latest B737NG's: frequency is preset on the right side (Standby) and become in use when transfered to the left side (Active), so no chance to "scan" the band! 1 Khz step, USB by default, AM possible, no more LSB.

- HF antenna

- HF automatic antenna tuner location on classic B737 series (-300/-400/-500)

APRS take place anytime unless few restrictions, SSB voice only during low cockpit workload: SAFETY FIRST!
