Thanks Ron,
I just went to the Webb site and listened to the ALE example.
That is it! Its an ALE call we hear.

>> >>Here is some info about ALE sounding and how it works.
>> >>
>> >>What is an ALE sounding?
>> >>In ham radio, ALE sounding is simply a station ID.
>> >>Only the callsign is sent, example "This is AA1BB".
>> >>Sounding is ALE jargon for "Station ID".
>> >>
>> >>What is the purpose of ALE sounding?
>> >>The ID is transmitted for the purpose of establishing
>> >>and maintaining communications with other stations
>> >>and to meet the station identification requirements
>> >>of ham radio rules and regulations. Sounding may
>> >>also be part of a selective calling process.
>> >>
>> >>How does ALE fit in the various ham radio rules?
>> >>How ALE sounding is applied to the different rules of
>> >>various countries depends upon that country. Under USA's
>> >>FCC rules, ALE sounding is a station ID and a communication.
>> >>
>> >>ALE sounding is not "beaconing".
>> >>ALE stations are not sending one-way transmissions like
>> >>a beacon does. All the ALE stations are transmitting and
>> >>receiving communications with all the other ALE stations
>> >>in communication with each other.
>> >>
>> >>What frequencies are soundings used by hams?
>> >>In ham-friendly ALE, part of the guidelines for
>> >>repetitive soundings is to transmit on "pilot channels".
>> >>Pilot channels are ALE jargon for a designated calling
>> >>frequency, usually only one channel per band. The pilot
>> >>channels are within a segment of the HF bands that are
>> >>designated for automatic operation by the national bandplans
>> >>or the IARU Region bandplans, depending upon which applies.
>> >>
>> >>Ham Radio ALE Pilot Channel Frequencies
>> >>
>> >>Freq kHz SSB INTERNATIONAL REGION - AREA
>> >>3596.0 USB NORTH AMERICA - SOUTH AMERICA
>> >>3617.0 USB EUROPE-AFRICA-RUSSIA-MIDEAST
>> >>3626.0 USB ASIA - AUS - NZ - PACIFIC
>> >>7040.5 USB EUROPE-AFRICA-RUSSIA-MIDEAST-S.AMERICA

>> >>Amateur Radio Global High Frequency Network (HFN)
>> >>The Amateur Radio Global ALE High Frequency Network
>> >>is a group of volunteer operators who have automatically
>> >>controlled data stations on the ALE Pilot Channels.
>> >>These are known as HFN Pilot Stations, and they provide
>> >>interconnect texting services and HF-to-HF Relay services.
>> >>The long term objective is to be interoperable with as
>> >>many different types of systems as possible. The primary
>> >>purpose of the HFN is to provide emergency and disaster
>> >>relief 24/7/365 communications. When not in use for the
>> >>primary purpose, hams may access any of the HFN stations
>> >>for normal use. Another secondary aspect of the
>> >>HFN stations is that they provide a continuous feed
>> >>to the internet, reporting all other ALE stations they
>> >>receive. This includes soundings and all other types of
>> >>ALE calls. These reports get logged into a permanent
>> >>database, and are visible on "ALE Channel ZERO".
>> >>http://hflink.net/qso
>> >>
>> >>Many other ham radio ALE operators are transmitting
>> >>soundings on the ALE pilot channels. The more operators
>> >>who are active on ALE, the better everyone is able
>> >>to connect with each other.

>> >>HAM RADIO SOUNDING INFORMATION
>> >>
>> >>What is Sounding?
>> >>In Amateur Radio ALE, a sounding is simply a 10 second ALE
>> >>transmission of your callsign (station identification). A sounding is
>> >>different from a beacon because the ALE station uses 2 way
>> >>communications; and the ALE sounding transmission is part of a
>> >>selective calling process for calling and actively maintaining
>> >>communication with other stations in the global ham radio ALE net and
>> >>individually.
>> >>
>> >>Why are Soundings Used?
>> >>The reception and communication through soundings enables other ALE
>> >>stations to know which frequencies or bands your station is active on.
>> >>When you first turn on your transceiver, you can send some soundings
>> >>so that other stations will copy your transmissions, and then may
>> >>selectively call you on the best channel, using the minimum number of
>> >>call attempts. The scanning ALE receiver listens to the soundings of
>> >>other stations each time they are heard and stores them in memory with
>> >>channels and times.
>> >>
>> >>How Are Soundings Transmitted?
>> >>Soundings can be manually transmitted, or set by the operator to
>> >>transmit repetitive soundings every hour. Usually, if repetitive
>> >>soundings are set, when the ALE controller or radio is first turned on
>> >>then there is a delay of a few minutes before the first soundings are
>> >>transmitted.
>> >>
>> >>Ham-Friendly ALE Soundings
>> >>In the ham radio ALE network, there are Pilot Stations in different
>> >>areas of the world that send soundings 24/7. This system transmits
>> >>sounding only on the Pilot Channels in the automatic station
>> >>sub-bands, and this strategy forms part of the basis of ham-friendly
> ALE.
>> >>
>> >>ALE Sounding Guidelines for Amateur Radio
>> >>
>> >>1. As an Amateur Radio Operator, you are responsible for all
>> >>transmissions of your station.
>> >>
>> >>2. Before sending soundings, or any transmission, listen carefully to
>> >>all your transmitting channels with your receiver. Avoid interference.
>> >>
>> >>3. Sounding is not CQ. If you want to call CQ, use the HFL or QRZ
> netcall.
>> >>
>> >>4. Manual or attended soundings may be transmitted on any ALE channel.
>> >>
>> >>5. For repetitive sounding, program your ALE to sound only on the
>> >>designated Pilot Channels marked PILOT in the Amateur Radio ALE
>> >>Channel List, for your IARU/ITU Region, and within your license. There
>> >>is one Pilot Channel per ham band in each Region.
>> >>
>> >>6. Program your ALE controller to use TWS Sound if possible. Using TWS
>> >>Sound increases the efficiency of ALE nets. Please DO NOT use This Is
>> >>Sound (TIS) on the ham bands.
>> >>
>> >>7. The optimum duration of a sounding transmission is approximately 10
>> >>to 15 seconds. Test and verify your sounding transmission duration
>> >>with your watch. A sounding transmission should NEVER be longer than
>> >>30 seconds!
>> >>
>> >>8. The optimum repetitive sounding on a channel is about once every 60
>> >>minutes. Please DO NOT sound repetitively on a channel more than 2
>> >>times per hour.
>> >>
>> >>9. The optimum scan rate is 1 or 2 channels per second. If you scan
>> >>more than 10 channels, use 2 channels per second.
>> >>
>> >>10. Check your transmitter operation and antenna system SWR regularly
>> >>on every channel in your scan group!
>> >>
>> >>11. Take care in programming your ALE controller (software) and
>> >>transceiver. Test it carefully and verify it for proper operation on a
>> >>dummy load before connecting your antenna.
>> >>
>> >>12. Use the Polite or Voice Detect or Busy Detect feature of your ALE.
