CALIBRATION
Most functions within the BayPac are self-calibrating. However, there are two
adjustments which must be made by the user since they vary with the type of
radio being used. The first is the modulation ‘‘Level Adjust’’ located on the
top of the BayPac unit. This adjusts the level of the tones going to the
microphone input of the radio. It must be set to provide a transmitter
deviation of about 4 KHz. The second adjustment is the receiver volume
control. This setting is not particularly critical. You may notice that the
calibration program has you set the level rather high. This is done so that the
BayPac can scale the level to its needs. Both of these adjustments can be
made using the BAYPAC.EXE program provided on the BayPac Setup Disk.
Instructions for making these adjustments are provided by a Help Screen
within the program. You will need a second receiver to listen to your signal
during the test. Be sure to perform the testing on an unused (Not Packet!)
frequency. Use a dummy load if at all possible and keep your transmissions
short.
CALIBRATION PROBLEMS
The tone level from the BayPac is adjustable from zero to about 1.25 volts
peak to peak. This wide adjustment range may cause the adjustment to be
critical on radios with very sensitive mic inputs. If you feel it is a problem in
your case, you can insert a resistor in series with the mic audio (Yellow line)
to reduce the sensitivity of the adjustment. The resistor value will vary with
the radio, but a good starting value is 10k ohms. The resistor will fit easily
inside the connector housing.
RF INTERFERENCE
The BayPac modem was designed with RF immunity in mind. Not only is its
circuitry designed to minimize the generation of radio emissions, but it is
also designed to suppress emissions from your computer. Nevertheless, if you
operate the unit in the presence of excessively high RF fields, you are
probably going to have problems with both the computer (especially laptops)
and the BayPac. If this situation is unavoidable, you can increase your
chances for success by using shielded cables from an interface box as shown
in figure 6. This approach is especially helpful when using an HT in portable
operation. RF induced problems are easily identified since they generally
cause the BayPac and/or computer to become totally inoperative (lock up).
You can reset either by simply turning off the power and then restarting the
program. WARNING
Excessively high levels of RF could permanently
damage your equipment. Try to keep your antenna at least a few feet away.
HELPFUL HINTS
Check the BayPac Setup Disk for the HINTS.DOC file containing operating
tips to increase your enjoyment of both the BayPac modem and the Baycom
software.

SUPPORT THE BAYCOM TEAM
The Baycom Terminal Program, written by DL8MBT and DG3RBU in
Germany, is the product of enormous effort and considerable expense.
Hopefully, the current release of Baycom is but the first in a series of releases
that will follow in the footsteps of its forerunner Digicom (Commodore 64).
Tigertronics encourages you to support the authors with a contribution to
their effort. You can find their address and further information near the end
