More adjustments done

Homemade Wrench pole.
Hard Work, Hi Hi.. 

Almost set. I believe all fine adjustments are done now.
Just one beam left to mount.
Will wait until after tomorrow.
Wind is coming - so, waiting for better WX Conds is better.

cosy... :-)

IC-9100, internal USB soundcard and PTT TX in WSJT

CAT7200 - originally created for IC-7200 to enable PTT via CI-V for RTS(request to send)
Reported to be working for Icom IC-7100.

I could not find any reports for it to work on IC-9100.
In Win2k8.1 I'm able to transmit in WSJT, WSPR, wsprx and wsjtx2.

Makes things so easy, when internally USB soundcard in the radio can be used.

Follow this to get it going:

Great stuff, John!

USB interface HRD and IC-9100

How to get TX/RX via USB using an IC-9100 and Ham Radio Delux >5.x

  • Install the USB driver from Icom first... then attach the radio.
  • Get your HRD up and running via USB-Serial(speed: 9600).
  • Choose your soundcard for TX/RX in DM780(in Win8.1: USB Audio CODEC)
  • For PTT - choose "via Ham Radio Deluxe - DM780 must be connected to HRD)
  • To make PTT work - assign TX button in DM780 to the physical TX button on the radio.

Voila !

Have fun!

Heavy stuff to do alone...

Hope for no rain tomorrow....
The rest will then be set.

Pretty heavy for the rotor to lift just 2 antennas on the H-Frame.
Weight balance in the frame will be much better when the 2 lower OWL's are set.

Still working on the antennas on the ground..
Possibly... getting them up tomorrow.
All bolts will be re-secured - all support-wire locks will be re-checked and attaching a support bolt for the Azimut rotator(to stop any potential unexpected turns in the wind):

Planning to attach the coax via the support boom for the upper antennas.
Lower antennas is on the antenna boom.

After checking - A1(upper left) has same SWR both when the W103 cable is on the antenna boom or is attached under on the under-boom.
So, I will reattach it back - and put it on under-boom.
Then the cable is following the H-Frame and not crossing the directors.

SWR plots.. A1, B1(lower left), C1 and D1

more to come..
