Well, it was only a matter of time until I could contribute to this topic... yesterday became "the time."
I was flying from KLAX to KSNA, LAXX6 departure, SLI transition, and the full ILS approach for 19R... piece of cake, eh? I was flying the Citation Mustang, and it was only my 3rd time flying it. I filed the flight plan, called CLNC and got my clearance, read it back and got "read back correct," which is somewhat of a novelty, eh Keith? The departure frequency I was assigned was 125.02, while I was expecting 125.20... but did I question it? Of course not... even though I had flown the I-05 30 minutes before, and 125.02 was Las Vegas Approach. Do you see it coming? ...wait for it! I called GRND, got taxi clearance, taxied to 25L, called the tower and took off... and that's about the last thing that went right! My apologies to the controller
Passing 1000 feet, I was watching for the needle to center for the SMO R-160 to make my outbound turn + trying to control my airspeed + moving the heading bug to make the outbound turn to 220. The TWR called and instructed me to switch to Departure, which I did. I called departure and got no response. I continued to try to get the unfamiliar airplane trimmed and climbing properly, etc., and suddenly realized that departure had not responded. By this time I was climbing through 3000. I called again, waited, got no response, checked to make sure I was transmitting on the assigned frequency, was on COM1, and that the PE radio panel showed me transmitting (there was no radio chatter at all, and we've all been disconnected, eh?). Now, I was passing 4,000, and called again... still no response, and I'm thinking even if I'm on the wrong frequency, someone will certainly call and inform me. Finally, I bypassed the obvious solution (switching back to TWR and informing them of no contact with departure-- nah, that's too easy), and the main temptation (disconnect and start all over), checked the departure plate, switched to 125.2 and called departure, now level at 5000. The controller informed me they had been waiting for me to call for 2-3 minutes, and told me I should have called the tower (DUH!

), etc... I thanked him for the correction and told him that I had been given the wrong frequency. He said, "...in that case, turn left to 100 and expect vectors to Seal Beach. Of course, by now, I was halfway to Hawaii

.
The controller then had to vector me all the way around the Palos Verde Penninsula (for noise). When he next called, I thought he would be turning me towards SLI, but alas, it was to give me a speeding ticket... I was doing 230 KIAS. He told me that the speed limit below class B airspace was 200 KIAS. Well, damn! First let me say that ignorance is no excuse. Second, let me say that my real world flying ended almost 30 years ago, and a 200 KIAS speed limit was never an issue in a PA28-140. Arrrggghhh!
What else could go wrong! OMG, never, never ask that question!
Finally, I crossed over SLI, made the entry for the procedure turn, returned to SAGER--SNAKE--LEMON, got response from the GS, switched to APR mode... and the AP refused to respond... I hand flew the airplane successfully, and finally, the torture ended!
Thanks to the controller, and to Pilot Edge, for providing me with this embarrassing moment... or two... or three!
The moral of the story, or at least one of them, is to keep flying the airplane (FTFA) and don't panic... and heaven help me, that's all I did right on this flight! With one final apology to the controller, I'll sign off and give everyone time to have a good laugh.
