Testing:
Double check all the soldering point then connect power and turn it on. If the current is around 80-90mA,
it’s OK to proceed. Current higher or lower than 90mA, there are issues that must be corrected before
processing.
Plug your headphone to phone jack, put signal generator to ANT, put generator with a 5uV signal, adjust
frequency to 7.100Mhz or close to this frequency, put EK-1A on same frequency, now adjust VC to receive a
700Hz beat frequency, then adjust T1,T2 to max the receiver sensitivity.
Please plug your key to Key/Paddle jack, test key, if it’s OK then testing finished. Now we can finish the
assemble.
Secure the back cover with screws, put studs on the display board and then secure the front cover. Install
two knobs, assemble finished.
