Hi Scott for what its worth :-))  my propagation forecast for night-time
paths for the weekend is "good" for the 1st and 2nd. There was a Class C3
flare at 0100 on the 1st which will not have any effect yet.  We are
expected to enter a high speed coronal hole flow on the 3rd, which could
combine with any earthward CME component associated with the flare. This on
northerly paths the propagation could decline to fair or poor on the 3rd. My
feeling is that it will not drop below "fair" so It seems as though you have
chosen a good time for your tests.
Good Luck
Alan G3NYK

> Gentlemen
>
> JA7NI and I will be conducting a unique beacon test on May 1st and 2nd.
>
> Purpose:
> To evaluate the transpacific path to determine the viability of a QSO
> using extremely long integration lengths while evolving procedures and
> experience to determine is a  QSO will be possible under 'normal'
> propagation conditions.
>
> Background:
> To date JH1GVY and JA7NI have both been seen at VE7TIL's QTH with
> useful signals.  Despite high power used by VE7TIL  no reception has
> been confirmed in JA.  JA7NI is working on improving RX capabilities
> while TIL works on improving TX antenna.
>
> Equipment:
> JA7NI - TX antenna T-shaped, 45m high (free and clear of trees).  TX out
> is 50W. RX Antenna beverage is 160m long, but he will shortly make it to
> 350m with a preamp connected.
> VE7TIL - TX antenna T-shaped 20m vert, 20m horz, located within trees
> (soon to expand topload to large triangle shape 20m each side and
> elevate 0.5-1mH of inductance). A transmit loop is being considered for
> future experimentation.  RX antenna, 150' resonated K9AY type phased
> with with other loop for noise canceling.  TX vertical used on
> experimental SDR setup as secondary RX.
>
> Details:
> Each station will transmit a single QRSS60 character on a predetermined
> schedule.  If the other station hears they will respond with the copied
> character.  If they don't hear they continue on the sked and transmit
> their own character.  This sequence will go on until the end of the sked
> timings.
>
> Duration - 10:30 - 12:30UTC  May 1st and 2nd
> JA7NI -  'J', 137777.7Hz,  10:30, 11:00, 11:30, 12:00
> VE7TIL - 'V', TX 137778.0Hz, 10:45, 11:15, 11:45, 12:15
>
> Reports:
> Strongly encouraged from any interested station to allow us to
> understand the capabilities of each station and establish performance
> datums given propagation data being collected.
