Don't know how Apex does it, it may be similar to how Channel Master did it.
But if you do use an external modulator, you may be able to change the channel it uses, from the usual 3 or 4 to 2, 5 or 6 by removing the usually 4 legged crystal and installing a regular 3rd overtone crystal cut for 55.25MHz for channel 2, 77.25 for channel 5 and 83.25 for channel 6. I found that crystals for 18.432MHz will also usually work for channel 2, 25.75MHz for channel 5 and 27.75 for channel 6. Depending on how much fine tuning the set's tuner will allow, 27MHz crystals from CB radios may work well enough. This assumes such crystals will oscillate in the channel 5 frequency region.
