After a half century in ham radio, my interest today has grown toward forging the future of the Amateur Radio Service through modernization of our HF communication systems and methods. I believe in the importance of hams embracing new technologies, especially in HF. Miniaturization, mobility and portability, interoperability, interconnectivity, as well as digitization of signals and selective calling systems are playing a big part in our future.HF is an extremely valuable resource at the core of ham radio. Background Story I learned morse code at the age of 8 and built my first AM radio on a breadboard kit at 11, from a box of transistors and parts. I rewound the coil with magnet wire and picked up some hams talking on 80 meters. I've been working in electronics ever since. After an early career with telecom networks and radio stations, my knowledge of the details and nuances of electronics increased... I wanted to create products and invent new things. I went into RF Engineering in Silicon Valley... designing such things as pagers, early cellphones, satellite gear, antennas, cutting-edge MRI machines, telecom equipment, and flat panel displays. As a corporate exec these days, I don't get as much time to do design engineering. Ham radio provides an outlet for that spark of electronic creativity.

HFpack Calling Frequencies
SSB, CW, ALE, or SELCALL may be used for calling or QSOs on the HFpack SSB Calling frequencies.
Standard CW Offset
Approximately +500Hz to +1500Hz CW freq offset is used on the HFpack HF Portable SSB calling frequencies. Cross-mode CW to SSB QSOs (Upper Sideband voice) are encouraged, especially when signal levels are low or conditions are not reliable for SSB-SSB QSOs.
USB. Note about Upper Sideband use by HFpack
Upper SideBand (USB) is the standard on all HF bands for HFpack SSB voice QSOs, including the bands below 10MHz! USB has become the international standard for non-amateur HF SSB voice and other modulation methods. The HFpack and HFLINK groups have adopted the UpperSideBand Standard to achieve complete compatibility with a wide variety of commercial and mil portable HF radio systems that amateurs are using. With the advent of simultaneous "multimedia" SSB voice, CW, image, text, selcall, ALE Automatic Link Establishment, HF-APRS, and digitized QSOs on the same channel, UpperSideBand standardization will become even more important.

AMATEUR RADIO ALE CHANNELS
All Amateur Radio ALE channels use "USB" Upper SideBand (including frequenciesbelow 10MHz). USB conforms to International Standards for Automatic Link Establishment,and enables interoperability.
This ALE channel list is in everyday use in theAmateur Radio service, for normal communication internationally, regionally, and locally. ALE channels are frequency coordinated internationally, and operators are subject to the differentrules, regulations, and bandplans of their region and local country ofoperation. There is commonly an ALE signal active on the air, every minute of every day on these frequencies. It is the responsibility of every ALE operator to maintain thehighest standards for all transmissions. Somechannels 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 achannel is clear in a local area or region. ALE uses LBT (Listen Before Transmit) If a channel is occupied at any given moment, ALE will try to select another channel instead.
Amateur Radio ALE standards:
1. ALE System= MIL-STD 188-141 ; FED-1045 (8FSK - 2kHz Bandwidth)
2. If repetitive sounding, transmit soundings only on the Primary Data Channels or Pilot Channels for your IARU Region.
3. Calling or sounding transmission: Maximum Duration = 22 seconds.
4. Sounding Interval= 60 Minutes (or more) for same channel.
5. When sounding, always use "This Was Sound" (TWS).
6. Scan rate: 1 channel per second when scanning 10 channels or less.
7. Scan rate: 2 ch/sec or faster when scanning 11 channels or more.
8. Digital Modes Centre Audio Frequency = 1625Hz
9. Short text messaging standard = AMD .
10. Always transmit "CLEAR LINK" after ALL CALLS, QSOs, and LINKS!
Amateur ALE Net Calls
1. HFN = Global ALE High Frequency Network (HFN) Calling any Data/Text ALE Station
2. HFL = Calling Any Voice SSB ALE Station
The 5MHz channels and band frequency segments vary in each country.
USA: Operators on the 5MHz channels may use NALE (Non-Automatic Link Establishment) with attended/manual sounding or no sounding.
HFLINK is an international resource: for radio operators using ALEAutomatic Link Establishment and Selcall Selective Calling; for thedevelopment of communications for organisations,Emergency / Disaster Relief networks; and for the development of ALE operatingmethods applicable to Amateur Radio Service. HFLINK is the Frequencyand Address Coordination group for International Amateur Radio ALE and SelectiveCalling.
