6. In Case of Difficulty

While   we   cannot   cover   every   possible 
problem, here are some hints for dealing with 
some   potential   difficulties.     Check   the 
obvious.     Is   your   dc   power   source   okay? 
Check power supply, cable and connector(s). 
Is   the   25   ampere   fuse   loose   or   missing? 
Antenna problems?  Try a dummy load.  Is a 
proper   antenna   connected?                 Is   any 
external   antenna   switch   connected   and 
properly   set?   Have   you   double-checked   the 
Argonaut   VI’s   many   control   settings, 
including   those   in   the   Configuration   menu, 
for your intended mode of operation? Have 
you   checked   how   the   optional   Filter’s   are 
installed   and   confirmed   their   installation 
order within the Configuration Menu?

One problem that results in no audio or poor 
audio is the fact that sometimes you make an 
adjustment   to   a   setting   and   subsequently 
nothing seems to work properly anymore. The 
method that resolves setting issues that you 
just can’t find, is to perform a Master Reset. 
This   was   discussed   in   the   “

General 

Operations

” section of this manual.

Problem:  No Receive Audio

Is the AUDIO (AF) turned up?
Is   RF   GAIN   turned   down?   Is   squelch 
activated?   SQL will appear in block letters 
on the screen.   Press FNC then FAST/SQL 
and check SQUELCH level. 
Is the speaker wire internal to the rig broken 
or disconnected?  (Have you pulled the covers 
off recently?)  Try headphones to see if audio 
returns.
Is NR off?  Under some circumstances, noise 
reduction   can   cover   band   noise  completely, 
leading the user to think no audio is coming 
from the speaker.

Problem: Distorted SSB transmit – or –
Perceived RFI in the shack.

Be certain the mic gain is set properly.   The 
ALC LED should flash on voice peaks, but 
not remain continuously lit in SSB modes.
Check the setting of the speech processor. An 
excessively   high   setting   can   reduce   audio 
quality. 
A frequent cause of a distorted SSB signal is 
inadequate   RF   grounding   resulting   in   RF 
feedback.   Common RF grounding problems 
are no ground connection, or too long a lead 
to a good ground.   Many problems relate to 
the   lack   of   an   RF   station   ground,   as 
contrasted  with a safety ground connection. 
We   recommend   bonding   all   equipment 
chassis together with short heavy metal braid 
or   strap.     Make   these   connections   from 
chassis ground lug to chassis ground lug and 
connect the last piece in the chain feeding the 
antenna   to   a   good   earth   ground.   This   lead 
needs to be as short as possible.  Lengths near 
¼   wavelength   on   any   band   used   can   be 
particularly troublesome when the far end is 
connected to earth. It is very important that 
the external power supply and the transceiver 
and   all   equipment   with   grounding   lugs   are 
properly grounded.
Another   potential   cause   of   distorted   SSB 
arises when the station is in the near field of 
the   antenna.       This   is   a   problem   many 
apartment dwellers face.  
Distorted   SSB   transmit   can   result   from 
chassis   ground   and   signal   ground   from   the 
microphone being tied together to a common 
connection.  This is a common problem with 
third-party microphones.   Assure the chassis 
ground   and   signal   ground   from   the 
microphone is separated.
RF can also be induced into the transceiver on 
any unshielded wires.
