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.
