That's interesting considering an FCC database search discloses that they have no license to operate on 461.7250 mhz. or 462.200 mhz. in Virginia. They are licensed as WPGZ424 to operate on 152.3600 mhz. (base) and 157.6200 mhz. (mobiles).
Most cab companies are very concerned that competitors will steal their fares. One local operation moved from UHF to 800 mhz. in an attempt to have "secure" communications from the competition. Frequently the competition would arrive before the
called cab and on occasion there were fist fights. An 800 mhz. trunk provider convinced them to move to 800 mhz. where their comms would be "private". He did not tell them their transmissions were analog in the clear and 99% were on the first
frequency in the trunked group. Their competition soon knew. Upon realizing their comms were not any more secure on 800 mhz. than UHF, they dropped 800 mhz. operation and reverted to a cheaper UHF two way operation. Speech inversion is a relatively
cost effective way for cab companies to achieve some level of comm security.
