THE MOST COMPACT 144 MHz MOBILE
The smalest 144 MHz mobile available, the IC-27H measures only 38 millimeters high by 140
millimeters wide. As an added bonus, the IC-27H. through ICOM engineering, is able to contain
an internal speaker to provide ease of mounting and make the unit one small compact complete
package
HIGH OUTPUT POWER
In such incredibly small package. the IC-27H is able to provide 45 watts of output power. And
even though the IC-27H is the smallest available two-meter mobile unit, it has sacrificed none of
the features found in fully featured VHF mobiles.
9 MEMORIES
The IC-27H has nine memories available to store receive frequency transmit offset, offset direction,
and subaudible tone.
Memories are backed up by a lithium backup battery, which will store memories for up to seven years.
32 SUBAUDIBLE TONE ENCODER
The IC-27H (U.S.A. version) comes complete with 32 standard subaudible tone encoder ready to
go and controlled from the front panel knob. Each subaudible tone may be selected by the main
tuning knob and stored into memory for easy access along with the frequency.
MULTI-PURPOSE SCANNING
The Memory Scan allows you to monitor nine different memory channels, the Programmed Scan
provides scanning between two programmed frequencies, and Full range Scan scans the entire band.
The scanning speed is switchable. and the auto-stop terminates scanning when a signal is received
or a channel is free.
PRIORITY SCANNING
Priority may be selected to be either a memory channel or a VFO channel. By using sampling
techniques. the operator can determine if a frequency he is interested in using is free or busy.
SPEECH SYNTHESIZER
As an added plus. the IC-27H features an optional speech synthesizer to verbally announce the
receiver frequency of the transceiver through the simple push of a button. This allows the operator
to hear what frequency he is operating on without looking at the frequency display.
I bought my unit when it was about 10 years old. It has been in my car for about a year. In the beginning I had problems with the squelch. This was however fixed by replacing the potmeter. Unfortunately, it is not industry standard and cost money. To be on the safe side I replaced both volume and squelch potmeters.
Operating the radio from the car is easy. The only snag is that I have placed it so that I sometimes accidently rotate the channelswitch away from my repeater channel. Therefore I miss a LOCK button. The sound from my mic gets good reports. 45 Watts gives a good takeoff when I drive through the landscape. The built in speaker has sufficient volume.
I have enjoied the rig and sold it to get a newer FT-8100R.
