Friends,

Thank you for the suggestions.  Please remember that my hobby time is very 
limited because the cold comes too fast in Yukon, and I must do extensive 
work on a house we are improving to become a rental unit for future 
retirement income and because my manager has given me self-training goals 
which are vital to my continued employment and present income.

I will not be able to spend much time developing these things, writing 
software and so forth.  Since Java is one of the languages I am learning, 
working on a program related to it can be a work-related exercise.  I need 
help to make transmitter and ancillary equipment building take less time and 
still have a good experiment result to present to the Radio Amateurs of 
Canada for its case to Industry Canada.

Experiment goal: beacon steadily at 1 W ierp until May when the license 
expires.

I must also reduce the amount of time I spend on email, so you will see 
fewer postings from VY1JA for the duration of the warm weather and while 
trade certification exams are being taken.

The reason I wanted to build a transmitter which it more powerful than 
needed is that I am hoping that when it is run so that it produces the 
current needed for 1 W ierp, it will be bulletproof like the amplifier which 
Steve, VE7SL has lent me and which is beaconing at 100 W now.  It takes 
antenna changes from weather and wind and keeps on playing.  I find that I 
can readjust it on the fly.  I want to build a robust 500-1000 watt rig, set 
it at the license power limit, forget it, and not be afraid that smoke 
signals is all I will be sending.

I have an RF ammeter which shows almost no antenna base current from 100 
Watt transmitter output. To get the 2.85 Amps will require much more power. 
I guesstimated about 410 Watts.  We will find out when there is an amplifier 
in place which can generate power enough to make that RF ammeter swing to 
the centre-scale.

Reception reports like the one John sent will be greatly appreciated toward 
the experiment report which I will be developing next May.

My brain function has improved but I still have a long way to go.  If you, 
my friends, can find solutions which are simple for me to implement, I can 
continue to improve the station, and keep experiments going but am mainly 
focused on keeping this property after my retirement.

Thanks,

J.
