The ICOM 3200A will normally cover from 140-150Mhz and from 440-450Mhz.
The search function of the radio, which can be accessed in either VFO A or B, has to be used to make the radio exceed the above noted coverage limitations.
The search feature causes the radio to scan every frequency between the preset limits. The lower limit is in Channel 0, and the upper limit is in Channel 1. For example, if Ch 0 contained 144Mhz and Ch 1 contained 145Mhz the radio would search, starting at 145Mhz, down until it reached 144Mhz. Of course it would stop on any frequency that broke the Squelch threshold.
If you changed Ch 1 to 446Mhz, the radio would search between 446Mhz and 144Mhz. However, it would skip 150.005Mhz to 439.995Mhz.
The trick is to change channels 0 or 1 to a frequency that is outside of the normal coverage range. Thus when you want to go outside of this range, use the search function in VFO mode with the squelch control fully counter-clockwise.
First, decide on whether you wish to go above 150Mhz, below 140Mhz, above 450Mhz or below 440Mhz. Please remember that the upper range will be in channel 1 and the lower range will be in channel 0.
Confused??? I thought so....How about an example.
Mission: receive normal coverage plus from 150Mhz to 152Mhz.
- go into VFO A mode.
- change the off-set to 10Mhz in the minus mode.
- select a tuning step of 15Khz
- select a frequency of 150.000Mhz
- press function.
- press and hold, very important not to let go, MR button.
- simultaneously turn channel selector knob one notch to the right.
- let go of MR button and press VFO select button TWICE.
- observe that frequency in VFO A is now 150.015Mhz.
- repeat from step 5 until frequency in VFO A is 152.000Mhz.
- store this frequency in channel 1 by pressing MR button.
Be careful, the radio will transmit out of band.
