|First Ham Radio 24/7 ALE |
HF Network is On The Air
with ALE-SMS Email
June 2007 - A team of radio operators successfully deployed 5
stations on the air, in the first phase of a global constellation of
ALE HF stations, in the new ham radio ALE HF Network. The new HFN Pilot
Stations are equipped with scanning ALE transceivers, multiband antenna
systems, and special software control systems. Ham radio ALE users in
the field on HF connect with the HFN Pilot Stations to exchange digital
ALE-SMS text messaging to and from internet devices such as cell mobile
phones, black berry type devices, PDAs, PCs and laptops. ALE users also
relay ALE messages to other ALE HF users via the same system. More information about the ALE High Frequency Network will be available soon.
|HFLINK Comments to ARRL on New Data Communication Protocols|
15 May 2007 - HFLINK responded to ARRL's February announcement
that it seeks comments from amateurs concerning development of an
open-source, non-proprietary, data communications protocol suitable for
use by radio amateurs over HF fading paths.
Read the HFLINK response letter here.
|ARRL's announcement was discussed at length in the HFLINK Forum.
The response includes recommendations, information, specific details,
and research on non-proprietary HF protocols that are presently
available for further development by the amateur radio community, and
adoption of these as ham standards for HF data communications and HFIP.
Hams can take advantage of the HF industry's vast research and
development through adoption of a suite of protocols based mainly upon
PSK and MFSK waveforms found in MIL, STANAG, and FED standards. HFLINK
recommends the immediate installation of an ALE station at ARRL's amateur radio station W1AW,
and the commencement of QST bulletins using ALE text messaging via AMD
and DBM formats, as a flagship example and a platform for the
advancement of new data communication protocols. The recommendations
include a basic common access layer using 141 ALE adaptions for amateur
radio, as the universal foundation, with a flexible array of several
high speed and robust formats and protocol layers for HF messaging,
chatroom, data transfer, SMS, email, and HFIP. Specifically, HFLINK
recommends that ARRL supports the development of a new PC software program that is modem-neutral, for HFIP, using the STANAG 5066 open 5066 standard. ...more info
||NOAA Forecasts Late Start for Solar Cycle 24
The next 11-year solar cycle will most likely start March 2008 and peak in late 2011 or mid-2012 – up to a year later than
expected – according to a forecast issued today by NOAA’s Space
Environment Center in coordination with an international panel of solar
|Originally expected to start between late 2006 and early 2007, the delayed onset of Solar
Cycle 24 stymied the solar expert panel and left them evenly split on whether a weak or
strong Cycle 24 lies ahead, but it seems at this point as though none of them are predicting a
record-breaker. In the cycle forecast issued today, half of the
panel predicts a moderately strong cycle of 140 sunspots, plus or minus 20, expected
to peak in October of 2011. The other half predicts a moderately weak cycle
of 90 sunspots, plus or minus 10, peaking in August of 2012. An average solar
cycle ranges from 75 to 155 sunspots. The late decline of Cycle 23 has helped
shift the panel away from its earlier leaning toward a strong Cycle 24. Now
the group is evenly split between strong and weak. ...more info
