I was departing LBB airport and the Ground Controller that I was talking to was
very hard to understand, I had to ask him to repeat himself multiple times. When
he informed me to squawk 5111 and departure frequency would be 119.3 I replied,
"Squawk 5111 frequency 119.3." He then attempted to inform me where to go on
the runway which I had him repeat three times. His instructions were to taxi to
Lima via Sierra. I then taxied to Sierra via Lima and held short of Runway 17R,
which he did not inform me to do. I held short because an aircraft was taking off I
then replied "Holding short at Sierra," he seemed put out by this. He then told me
to change to tower on 120.5 I misunderstood him and switched to the wrong
frequency I don't remember what it was, but I switched back and he repeated
120.5 and seemed very frustrated with me, he then made me wait about 3 minutes
until the King Air arrived at Taxiway Victor. He cleared the King Air to depart then
me. When I was cleared to takeoff Runway 17R I was advised "caution wake
turbulence behind the King Air that I was following." I replied, "Cleared 17R caution
wake turbulence." When I took off I was cleared for frequency change, I then
changed frequencies to 119.3 and called about 2 to 3 times. My aircraft was very
hard to control, I assumed it was the wake turbulence of the King Air, so I pitched
up for Vx to avoid the turbulence. I had no response so I turned to my on course
heading to avoid any other turbulence and repeated to contact departure. I then
decided to look over my flight plan and found that LBB departure frequency was
119.5. I the reported to 119.5 and was informed that I need to report my deviation.
Synopsis
A light plane pilot encountered wake turbulence after takeoff behind a King Air,
causing some control difficulties.

Narrative: 1
We were on the SEAVU arrival into LAX. We had experienced some wake turbulence
on the arrival since we were following a larger aircraft. The autopilot was turned off
during the wake turbulence and the First Officer was hand flying the aircraft. I was
busy trying to re-engage the NAV mode since it was also disengaged for some
reason. We were issued instructions to descend via the SEAVU arrival and cleared
for the 25L approach (we both thought he said 25L). I was then trying to figure out
what altitude to put in the altimeter. Once we were set up and tracking the 25L
localizer we were switched over to a different approach controller. After we checked
on with final approach we were asked by the Controller which localizer we were
tracking. I responded with 25L. He said we were supposed to be on 24R. He gave
us a heading and told us to intercept the 24R localizer and cleared us for the
approach. We had no other problems with the flight after that. We had planned for
25L and were busy dealing with wake turbulence and automation when we were
cleared for the approach. Fatigue was a factor as well since it was late at night. I
had flown a redeye the night before and did not get much sleep during the day on
my layover. LAX can be a tricky airport to fly into since they clear you to descend
via the arrival and clear you for the approach at the same time. We were never told
which runway to expect ahead of time and there was absolutely no emphasis on
the runway we were cleared for. When the only communication is "Cleared to
descend via the SEAVU 2 arrival and cleared for the 25L arrival" it can get a little
