H. LATE NOTES
If you wish the QF-1A to drive a speaker in “bypass”
you must obviously connect the QF-1A input to a rig
output which is capable of driving a speaker. (Some
headphone outputs, but not all, can drive a speaker).
When the filter is “on” virtually any high-level rig
output can drive it.
However, in “bypass” the rig’s output is connected
directly to the QF-1A output jack - The rig must be
capable of driving the speaker, if any, connected to the
QF-1A output!
I. REIALIBILITY
The QF-1A has proved to be extremely reliable. In the
past most units returned had nothing wrong with them.
RF pickup seems to have been virtually eliminated,
however if pickup should occur, we emphasize again
that there is nothing wrong with your unit. Any
problem must be solved in your shack. (See section:
“In case of trouble”.) Reports are that all owners have
been successful, usually by eliminating ground loops,
or using an AC line filter, in these rare stubborn cases.
J. TECHNICAL SUPPORT
Please utilize on-line Amateur (HAM) radio web sites
for questions regarding operation of this unit beyond
the scope of this documentation. Most HAM radio
sites have message forums (Q&A databases) that are
frequently viewed by experienced knowledgeable
people.
