Never repair a blown fuse with “silver paper” or with aluminium foil! Use only
“USA” type glass fuses with 2 to 2.5 Ampere. If the fuses keep blowing, check
for correct DC polarity, and if necessary, please give your radio set to your
servicing dealer to be repaired or hand it in to Albrecht’s service station.
voltage variation for this radio is up to 15.6 volts. Never exceed this voltage
under no circumstances! The transmitting stages for your AE 4190 are
electronically stabilized, and therefore it is impossible to increase output by
means of excessive supply voltage. Such attempts may lead to serious damage
to the radio set but will never increase output power!
Antenna connection
Connect your CB antenna to the ANT socket on the rear side of your ALBRECHT AE
4190. Most CB antennas must be tuned to best radiation during installation to give
highest effective communication range. CB specialists do that job with a standing wave
meter to check and adjust the aerial. Tune the aerial to the best standing wave ratio
(SWR) on an intermediate channel e.g. using Channel 1 in 80/12 mode (26.965 MHz) or
Channel 20 in all other modes.
On this channel you should attain a SWR of approx. 1.5 or less. If the SWR deteriorates
on the highest (Channel 40) and lowest (Channel 41) channels up to a value of 2.5, then
your aerial is still acceptable. SWR above 3 is too bad for good communication range.
A bad SWR may also indicate that there is perhaps an installation error or missing
ground. Problems may be caused through missing ground, especially in boats and
motor homes with fiber glass body. For these cases, Albrecht offers a special
connecting cable with matching box as “artificial ground” (AKM 27)
Some antennas, like “Gamma II” are broadbanded and do not need any
retuning during installations.
Even if your AE 4190 has a particularly robust transmitter high-level
stage which can even withstand mismatching of SWR=3, you
should still never transmit without an antenna!
