8) Next you should perform a RESET on the Argonaut by first turning OFF the
AF/Power
switch and then turning it back on while holding down the
FUNC
button.
!
9) The display should briefly show (Fb. 1.08) followed by (14.000.000).
!
10) Release the
FUNC
button and the display will show (14.250.000) and you are ready to go.
Resetting the Mic Gain After the 1.08 Update:
!
1) Connect a dummy load (preferred) or antenna to the ANT connector on the rear of the radio.
!
2) Place the Argonaut on the 20M band and in USB mode.
!
3) Connect a microphone to the MIC jack on the Front Panel.
!
4) Set the Front Panel MIC Gain control at about the 9 O’clock position.
!
5) While talking into the mike at a normal volume level, adjust the MIC Gain trimpot, located
on the top side of the Logic Board, until the ALC light on the Front Panel lights on voice
peaks.
Checking QRP CW Transmitter Output Levels:
!
1) Place the radio into CW Mode using the MODE button.
!
2) Turn the PWR control fully counter-clockwise to set the transmitted power level to minimum
QRP level.
!
3) Plug your keyer into the CW jack on the Rear Panel of the Argonaut.
!
4) Turn the PWR control fully counter-clockwise to set the transmitted power level to minimum
QRP level.
!
5) While sending a string of “dits”, press the KEYR button and set the keyer speed to “OFF”.
This will allow you to send a continuous carrier while the “dit” key is held down.
!
6) While sending a carrier, as described above, press the V/M button to place the Meter into low
power range. The meter will now read 5 Watts full scale until the key is released. Each time
you wish to use the low power scale you must press the V/M button while the radio is keyed.
!
7) Check the output reading on each band to ensure that the output is less than or equal to 2
Watts. NOTE: It is normal for the output to vary from band to band. The 40M and 30M
bands in particular will be higher than the rest of the bands.
!
8) If all bands check out OK, proceed to
Finishing UP
. If one or more bands QRP level is
higher than you would like to see, this can be lowered further by changing the value of R212,
which was modified earlier in step #5 under “Modifying the Logic Board”. Most radios will
work fine with the 10k ohm resister installed in this step, however, due to manufacturing
tolerance variations you may have to replace the 10k ohm with a 6.8k ohm resistor to get the
minimum QRP levels down further. Just follow the same procedures used previously to
replace the 10k ohm resistor with the 6.8k ohm. Check the QRP output levels again after
making this change.
