[NLRS] 10 GHz Cumulative and web page

[Chris Cox]

I had noticed that too, however, I just edited the formula to reference 
the km cell rather than the miles cell.  I also edited the km cell formula 
to round the distance to the nearest whole kilometre as before that it was 
simply usinf the integer value and always rounding down.

Thanks to all that were out this weekend and apologies to those I missed.

Perhaps the best part so far for me was to FINALLY isolate my abysmal 
receive problem.  It turned out to be the short UT-141 section that ran 
from the TCXO relay to the bulkhead SMA socket.  I still don't understand 
how the performance didn't improve when we previously tried bypassing it, 
but that was indeed the culprit.

Having found that there was yet another problem biting me.  This time on 
transmit.  The 12 to 24 volt doubler that drives the TCXO relay had failed 
and was only emitting 12 volts which was by far insufficient to pull in 
the relay.  So, having isolated that one at the third site I tried 
operating from, I continued out the day by using two 12V gel cells in 
series and manually switching the relay when going to transmit.

I got up early this morning and repaired these two defects.  I built a 
DEMI-standard relay/capacitor charge pump onto a small piece of Veroboard 
that was in the box already and then drove over to Lenny's cul-de-sac 
about 1 mile away.  Worked a number from there before returning home to do 
the fanily stuff I had comitted to.  Gary, W0GHZ, and I rangchewed on 
10368.1 for about 25 minutes whilst Gary, LJC, and Bruce, 'FZ, moved on to 
there second site for the day.  It was kind of fun to be passing 
coordination traffic back and forth on 10GHz as the two metre FM rigs 
weren't able to handle the paths for Bob, AUS, and Lenny, SHF!

I was teling Gary about a really neat five-legged switching power 
regulator chip that's available.  This chip will step up a 5-15V DC supply 
to a fully-regulated 3 to 60V output at 2 amps.  I am using this device in 
my backup transverter that I'm building to run the brick oscillator.  A 
full circit diagram fo rthe part is available at the folowing URL:-

The device is available form Digikey and costs about $5.

See you in September!
