New SKYWARN Standard Operating Procedures (SOP) Posted

Our ARLinks Skywarn Team has been busy working on an updated version of our new Skywarn Standard Operating Procedures (SOP).  The team is lead by Randy Wright, AE5RW and with assistance from Josh Carroll, N5JLC.  In all, there are 10 members on this important team.  Please familiarize yourself with our new procedures.  The new SOP represents much input and many suggestions from club members over time, along with input from other Skywarn organizations and personnel from the National Weather Service (NWS) Forecast Office in North Little Rock.  This SOP remains in draft form at this time and if you have input or would like to make a suggestion, please contact one of the team members as soon as possible.  The CAUHF Group may vote to adopt or reject the new SOP document at the next regular meeting on July 9, 2018.

Let’s All Get Together! 

baofeng_UV82For quite some time, we have considered establishing standard simplex frequencies for use within the CAUHF Group (and for anyone else who wishes to play along with us).  All of these frequencies fall within the ARRL Band Plan for VHF and UHF.  Here’s what we’ve come up with thus far.  We will not use PL tones on any simplex frequency (unless it becomes necessary in the future).  During special events, disaster drills, etc., we can refer to these as “tactical channels”.  Please program all of these simplex frequencies into your mobile radios and HT’s.  You never know when you might need them.

VTAC Channel VHF UTAC Channel UHF
VTAC-1 National Simplex 146.520 MHz UTAC-1 National Simplex 446.000 MHz
VTAC-2 146.535 MHz UTAC-2 446.025 MHz
VTAC-3 146.550 MHz UTAC-3 446.050 MHz
VTAC-4 146.565 MHz UTAC-4 446.075 MHz
VTAC-5 146.580 MHz UTAC-5 446.100 MHz

Some folks just pick any old frequency for simplex but that really is not wise.  If you are not careful, you can accidentally pick a repeater frequency.  Also, you must remember that VHF simplex frequencies need to be at least 15kHz apart and UHF simplex frequencies need to be at least 25kHz apart (as shown above) to avoid interfering with each other.  We began with the VHF National Calling Frequency as the baseline at 146.520, then for each succeeding “channel”, we went up 15kHz.  We also began with the UHF National Calling Frequency as the baseline at 446.000, then for each succeeding “channel”, we went up 25kHz.  At this point, this is merely a proposed plan–just a suggestion.  Let’s hear your thoughts.
