Narrative:

At XX58 pm, the sac local controller heard an unidentified voice hail an aircraft in the airport traffic pattern. The voice called itself 'base station' and told small aircraft X to change to frequency 122.85. Small aircraft X replied with 'roger.' soon thereafter, the voice told small aircraft X to 'disregard 122.85, base station doesn't have 122.85.' when small aircraft X was safely on the ground and taxiing on ground control frequency, an unidentified voice called to small aircraft X 'nice landing.' FSS specialist at XY15 pm engaged an individual at the base of sac tower in conversation. This man identified himself as mr X, sacramento, ca. Mr X said that he was talking to his brother in small aircraft X by using his hand-held radio. He related that, although he knew it was wrong, he felt that talking to his brother while in the air would be neat. Supplemental information from acn 251114: my brother was flying from wvi to sac. I was at sac waiting for his arrival with a new hand-held aircraft radio which I wanted to test out. I have an aircraft license for the radio. When the plane was 10 mi out from the airport on approach, I briefly tried to contact his small aircraft on tower frequency 119.5, I did not talk over any other pilot or the control tower. I briefly requested that he change his frequency to 122.85 (coordination of aircraft and ground station). Because he only had 1 radio on the plane, he was not able to change channels since he needed to stay in contact with the control tower. I then attempted no further radio communication with him. At the time I did this, I thought it would be permissible to be able to use the tower frequency to briefly request the pilot to change to another channel, which would allow ground communication. Sac FSS took my name and address and reported me to the FCC.

Title: UNAUTH ILLEGAL USE OF ATC LCL GND CTL FREQ. VIOLATION FARS. VIOLATION FCC REGS.

Narrative: AT XX58 PM, THE SAC LCL CTLR HEARD AN UNIDENTIFIED VOICE HAIL AN ACFT IN THE ARPT TFC PATTERN. THE VOICE CALLED ITSELF 'BASE STATION' AND TOLD SMA X TO CHANGE TO FREQ 122.85. SMA X REPLIED WITH 'ROGER.' SOON THEREAFTER, THE VOICE TOLD SMA X TO 'DISREGARD 122.85, BASE STATION DOESN'T HAVE 122.85.' WHEN SMA X WAS SAFELY ON THE GND AND TAXIING ON GND CTL FREQ, AN UNIDENTIFIED VOICE CALLED TO SMA X 'NICE LNDG.' FSS SPECIALIST AT XY15 PM ENGAGED AN INDIVIDUAL AT THE BASE OF SAC TWR IN CONVERSATION. THIS MAN IDENTIFIED HIMSELF AS MR X, SACRAMENTO, CA. MR X SAID THAT HE WAS TALKING TO HIS BROTHER IN SMA X BY USING HIS HAND-HELD RADIO. HE RELATED THAT, ALTHOUGH HE KNEW IT WAS WRONG, HE FELT THAT TALKING TO HIS BROTHER WHILE IN THE AIR WOULD BE NEAT. SUPPLEMENTAL INFO FROM ACN 251114: MY BROTHER WAS FLYING FROM WVI TO SAC. I WAS AT SAC WAITING FOR HIS ARR WITH A NEW HAND-HELD ACFT RADIO WHICH I WANTED TO TEST OUT. I HAVE AN ACFT LICENSE FOR THE RADIO. WHEN THE PLANE WAS 10 MI OUT FROM THE ARPT ON APCH, I BRIEFLY TRIED TO CONTACT HIS SMA ON TWR FREQ 119.5, I DID NOT TALK OVER ANY OTHER PLT OR THE CTL TWR. I BRIEFLY REQUESTED THAT HE CHANGE HIS FREQ TO 122.85 (COORD OF ACFT AND GND STATION). BECAUSE HE ONLY HAD 1 RADIO ON THE PLANE, HE WAS NOT ABLE TO CHANGE CHANNELS SINCE HE NEEDED TO STAY IN CONTACT WITH THE CTL TWR. I THEN ATTEMPTED NO FURTHER RADIO COM WITH HIM. AT THE TIME I DID THIS, I THOUGHT IT WOULD BE PERMISSIBLE TO BE ABLE TO USE THE TWR FREQ TO BRIEFLY REQUEST THE PLT TO CHANGE TO ANOTHER CHANNEL, WHICH WOULD ALLOW GND COM. SAC FSS TOOK MY NAME AND ADDRESS AND RPTED ME TO THE FCC.
