German callsign on the basis of French one: F1MHV
Unfortunately, not able to speak German, only French & English, sorry.
Operating mainly /Aero Mobile on HF and /P on VHF & UHF, D-STAR some times, testing 30m & 20m HF APRS/AM: DF1CHB-11, tx only ( http://aprs.fi/#!call=a%2FDF1CHB-11&timerange=43200&tail=43200 )
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!!
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.
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)
- HF transceiver part of the HFS-900 system. Some provide 2000 to 29999 Khz, some are limited from 2800 to 23999 or 26999 Khz. 400W PEP.
- HF transceiver in avionic bay located bellow the cockpit
- On the newest 737NGs, HF transceiver is located aft, beneath the vertical stabilizer in order to shorten the coax lenght. On the pic bellow, there is a free space in the rack for the missing HF2. Behind the HF rack, flight recorders are visible.
- Headsets are Sennheisers, mostly HME45-KA
- Audio panel
- SELCAL panel: on the picture bellow, SELCAL (http://www.selcalweb.co.uk/)was trigged by SM7DTT on 20m when flying west of Morocco coastline, using an mp3 file of the audio selcal code created using Multimode software (http://www.blackcatsystems.com)for Mac OSX.
- Sample of SELCAL coder used by ground stations
Hobby has no priority over flight duties: SAFETY FIRST!
Conditions to be "On Air": cruising level, low workload, low traffic airspace, well common sense!
I might have sometimes difficulties to copy calls and other figures, beside "standard" QRM, you might consider:
1) always dual (sometimes triple) frequency watch: always emergency 121,500 Mhz on VHF n°2
2) Boeing 737s cockpits are noisy compare to modern aircrafts such as A320 or Fokker 100/70. ;-)
