HFLINK NEWS    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 experts. 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 What is ALE?

(read more) How ALE Works ALE Automatic Link Establishment is a direct radio-to-radio calling system, that requires no infrastructure, no internet, no schedules. It uses a digital signal on HF or VHF to connect. Each ham radio ALE station uses the operator's callsign as the calling signal. When not actively in a QSO with another station, each HF SSB transceiver constantly scans through a list of frequencies, listening for its callsign. To reach a specific station, the caller simply enters the other station's callsign just like...

USB conforms to international standards for ALE / Selcall, and enables compatibility with commercial transceivers. Note 2 The ALE-Selcall list is designed for international, regional, and local use in the Amateur Radio Service. All channels are subject to the different rules, regulations, and bandplans of the region and local country of operation. It is the responsibility of every operator to maintain the highest technical and ethical standards for all transmissions. Some channels or modes in the list may not be available in every country. The HF spectrum is a shared resource, so there is no guarantee that a channel is clear in a local area or region. Note 3 Amateur ALE standards: 1. ALE System= MIL-STD 188-141 ; FED-1045 (8FSK, 2.2kHzBW) 2. Call or sounding transmission duration: 30 seconds or less. 3. Scan rate: 1 or 2 channels per second. 4. Sounding Interval= 60 Minutes (or more) (for same channel) 5. CQ Call= Netcall to "HFL" net 6. Digi Texting Audio Centre Frequency= 1500HZ (to 1800HZ) 7. Short text messaging standard = AMD 8. TWS SOUNDING (Recommended) 9. Always transmit "CLEAR LINK" after ALL CALLS and LINKING! Note 4 Amateur ALE Net calls 1. HFL = CQ, ALL AMATEUR RADIO ALE STATIONS  2. HAM = EMERGENCY/RELIEF NET ONLY, AMATEUR:NGO/GOV 3. GPR = GEO POSITION REPORTS 4. RPT = STATION STATUS REPORTS 5. QRZ = REPLY CALL PROMPT 6. CQA = RESERVED FOR FUTURE USE Note 5* The 5MHz channels' use and frequencies may vary in each country. Although 5MHz ALE and SELCALL transmissions are authorised in some countries, USA does not yet allow it on 5MHz. Therefore, operators in USA may receive monitor the 5MHz channels, but care should be taken to lock out the transmitter from making ALE or Selcall transmissions (except in case of an Emergency). See your country's rules. Note 6 HFLINK is an international resource: for radio operators using ALE Automatic Link Establishment and Selcall Selective Calling; for the development of communications for organisations, Emergency / Relief networks; and for the development of ALE operating methods applicable to Amateur Radio Service. HFLINK is the Frequency and Address Coordination group for Amateur Radio ALE and Selective Calling. All coordination is on a voluntary basis. Note 7 This channel list is located on the internet at  http://hflink.com/ Date Effective on 15 December 2006 (15/12/06), this list supersedes all previous channel lists.
