January 2016 Technical Talk

The technical talk at the January monthly meeting was given by Rob VK6LD. Rob's system is using a ICON 706 with a pair of remote boxes, one radio box attached to the radio at his QTH and the control attached to head of the radio at his portable station. Between the remote boxes is some form of network, ethernet network or internet. At the end there was a small show, tell and demonstration of listening on different bands at his QTH in Albany, and a look at the web interface to the remote unit.

So the crux of it is, Rob can sit in his car with a good 3/4G connection and remote control his rig at his QTH in Albany. That gives me an extended definition of going 'mobile' or 'portable'.

More information from the links below, Remote Rig USA manufacturer, and complete presentation pdf of Rob's talk.

Appreciate the talk Rob.

Happy Birthday Yagi

In AR circles that word rings a bell. Yagi, yes, antenna with greater gain than a wet piece of sting. But the birthday is for the gentleman that developed and named the antenna, Hidetsugu Yagi. Born on January 28 1886 in the Prefecture of Osaka, Japan. He graduated from Tokyo Imperial University in 1909 and continued studying in England, America and Germany after 1913. Back in Japan at Tohoku Imperial University with Shintaro Uda they designed the Yagi-Uda antenna and Yagi was given the patent in 1926, patent number 69115 in Japan and 1,860,123 in USA in 1932.

2015 Aug Talk - Grounding Systems

Terry, VK6ZLT gave another lively talk, this one on grounding in the ham stack. He took us through several scenarios of what to do and what not to do, with great emphasis on an accumulation of small faults add up to big RFI, for example ground loops.

Bob, VK6PO also gave instruction on how to properly gather up an electrical cable. This may seem a simple job to over-look, but twisted electrical cable can fray and expose live-wires. Tie a piece of cord or velcro at the male socket end, so you have something to tie the cable together at the end. Then start at the female socket end, and coil the cable with a under, then over hand movement, so that the cable is coiled one way, then coiled in the reverse way. Tie the coil off with the cord or velcro, then pat yourself on the back, good job.
