ATS-4a field tested with KI6J End Fed Matcher

ATS-4a in use in VA at portable location

KI6J Matcher with #22 teflon 1/2 wave for 20M

KI6J Matcher 'hooked up' on 20M

Put both the ATS-4a and the KI6J matcher on a field test at the portable location in VA.  The half wave wire was indoors on the 2nd floor and contact was made with an F8 with a 579 report!  The LED worked on the matcher to tune the antenna and several US contacts were also made.  The power supply was a 4.5 AH Gel Cell.  The headphones were Skull Candy ear buds and the Vibroplex Code Warrior Jr. works without the plastic paddles too.

NorCal S1-S9 Xtal Socket Mod

Original 10Mhz Xtal in Socket

Socket Added

A left over piece of the LCD socket from the Code Reader is the same pin spacing as the xtal if you cut off the 'middle' pin.  After soldering the socket in position '3' now becomes a socket and I tried testing HC-29 and HC-6 crystals for testing.

KI6J End Fed Matcher in Box

KI6J in plastic box

Matcher with Lid and 5000 Ohm 'antenna'

Got the Dremel and cut some holes in the Rat Shack box to mount the KI6J End Fed Matcher in.  The 5000 ohm resistor will simulate a half wave end fed for testing.  The switch will switch the bridge circuit and LED in/out for tuning with the capacitor.  The LED will dim when the bridge is balanced and the match is close to 50 ohms.  Then throw the switch to xmit without the bridge.  A previous post has more info on this kit and a schematic.
