On departing runway 09 at yakima airport, my clearance was to fly direct to the ykm VOR, thence on V298 nwbound, a magnetic course of 310 degrees. The VOR is located just a short distance from the airport to the northeast. After liftoff, I flew runway heading while attempting to identify the VOR and center the CDI to the VOR. I did not get an identify or a to flag, so executed a climbing left turn toward the VOR area. I finally got an identify and determined I had flown past the VOR to the northwest. I turned back to the VOR, continuing to climb. ATC queried my intent, apparently noting I was not established on course. I advised I was returning to the VOR and would proceed on course. After crossing the VOR, I turned on course, but again lost my identify. My original indication before losing the identify was I needed to turn right to intercept the 310 degree outbnd right. I was flying a heading of approximately 330 degrees when ATC again asked why I was off course. I replied I was not receiving the VOR and they advised I was well right of course and to turn wbound, maintaining VFR conditions, as I was nearing a restr area. Their original heading apparently took me into a portion of a restr area as I got back on course. In the meantime, I dialed in the VOR on both navigation's, received clear idents, and verified with ATC my position as to what radial I was crossing. ATC suggested a return to the airport because of possible unreliable equipment. (They advised other aircraft were receiving the VOR with no problems.) I determined to continue the flight, as both navigation radios appeared to be working normally. My biggest error as I see it was in failing to maintain visually my position (other than terrain clearance) while dealing with my problem. When ATC asked my position, I believe I told them I was northwest of the VOR when I was really northeast--a simple visual check would have verified this. I was preoccupied with flying the airplane and figuring out why I wasn't picking up the VOR. (Note: prior to this flight, we had come into yakima from pendleton, or on V4 and I had received the ykm VOR with no problem.) I did have 2 passenger and had them scanning for other aircraft, but I should have stayed more aware of my position visually, so as not to get in the proximity of the restr area. A second problem on this same flight dealt with icing. I had flown in ykm some 45 mins prior to departure on this flight from sun valley, and had been at 12000' MSL in the clouds from pendleton, or, to ykm, with no ice at all. In ykm, my briefing for the flight to sea indicated forcasted icing conditions along the route above the freezing level to the tops at 15000' MSL. Since I had just been there, with no icing. I determined to go. Sure enough, during the climb out, we started picking up rime ice at approximately 9000' MSL, climbing to 12000'. We aborted the flight, diverting to ellensburg. I simply should not have gone with reported conditions, even though I had not experienced icing on the earlier flight.

Title: PLT DEVIATED FROM ASSIGNED CLRNC, PENETRATED RESTRICTED AIRSPACE.
Narrative: ON DEPARTING RWY 09 AT YAKIMA ARPT, MY CLRNC WAS TO FLY DIRECT TO THE YKM VOR, THENCE ON V298 NWBOUND, A MAGNETIC COURSE OF 310 DEGS. THE VOR IS LOCATED JUST A SHORT DISTANCE FROM THE ARPT TO THE NE. AFTER LIFTOFF, I FLEW RWY HDG WHILE ATTEMPTING TO IDENT THE VOR AND CENTER THE CDI TO THE VOR. I DID NOT GET AN IDENT OR A TO FLAG, SO EXECUTED A CLBING LEFT TURN TOWARD THE VOR AREA. I FINALLY GOT AN IDENT AND DETERMINED I HAD FLOWN PAST THE VOR TO THE NW. I TURNED BACK TO THE VOR, CONTINUING TO CLB. ATC QUERIED MY INTENT, APPARENTLY NOTING I WAS NOT ESTABLISHED ON COURSE. I ADVISED I WAS RETURNING TO THE VOR AND WOULD PROCEED ON COURSE. AFTER XING THE VOR, I TURNED ON COURSE, BUT AGAIN LOST MY IDENT. MY ORIGINAL INDICATION BEFORE LOSING THE IDENT WAS I NEEDED TO TURN RIGHT TO INTERCEPT THE 310 DEG OUTBND R. I WAS FLYING A HDG OF APPROX 330 DEGS WHEN ATC AGAIN ASKED WHY I WAS OFF COURSE. I REPLIED I WAS NOT RECEIVING THE VOR AND THEY ADVISED I WAS WELL RIGHT OF COURSE AND TO TURN WBOUND, MAINTAINING VFR CONDITIONS, AS I WAS NEARING A RESTR AREA. THEIR ORIGINAL HDG APPARENTLY TOOK ME INTO A PORTION OF A RESTR AREA AS I GOT BACK ON COURSE. IN THE MEANTIME, I DIALED IN THE VOR ON BOTH NAV'S, RECEIVED CLR IDENTS, AND VERIFIED WITH ATC MY POS AS TO WHAT RADIAL I WAS XING. ATC SUGGESTED A RETURN TO THE ARPT BECAUSE OF POSSIBLE UNRELIABLE EQUIP. (THEY ADVISED OTHER ACFT WERE RECEIVING THE VOR WITH NO PROBS.) I DETERMINED TO CONTINUE THE FLT, AS BOTH NAV RADIOS APPEARED TO BE WORKING NORMALLY. MY BIGGEST ERROR AS I SEE IT WAS IN FAILING TO MAINTAIN VISUALLY MY POS (OTHER THAN TERRAIN CLRNC) WHILE DEALING WITH MY PROB. WHEN ATC ASKED MY POS, I BELIEVE I TOLD THEM I WAS NW OF THE VOR WHEN I WAS REALLY NE--A SIMPLE VISUAL CHK WOULD HAVE VERIFIED THIS. I WAS PREOCCUPIED WITH FLYING THE AIRPLANE AND FIGURING OUT WHY I WASN'T PICKING UP THE VOR. (NOTE: PRIOR TO THIS FLT, WE HAD COME INTO YAKIMA FROM PENDLETON, OR ON V4 AND I HAD RECEIVED THE YKM VOR WITH NO PROB.) I DID HAVE 2 PAX AND HAD THEM SCANNING FOR OTHER ACFT, BUT I SHOULD HAVE STAYED MORE AWARE OF MY POS VISUALLY, SO AS NOT TO GET IN THE PROX OF THE RESTR AREA. A SECOND PROB ON THIS SAME FLT DEALT WITH ICING. I HAD FLOWN IN YKM SOME 45 MINS PRIOR TO DEP ON THIS FLT FROM SUN VALLEY, AND HAD BEEN AT 12000' MSL IN THE CLOUDS FROM PENDLETON, OR, TO YKM, WITH NO ICE AT ALL. IN YKM, MY BRIEFING FOR THE FLT TO SEA INDICATED FORCASTED ICING CONDITIONS ALONG THE ROUTE ABOVE THE FREEZING LEVEL TO THE TOPS AT 15000' MSL. SINCE I HAD JUST BEEN THERE, WITH NO ICING. I DETERMINED TO GO. SURE ENOUGH, DURING THE CLBOUT, WE STARTED PICKING UP RIME ICE AT APPROX 9000' MSL, CLBING TO 12000'. WE ABORTED THE FLT, DIVERTING TO ELLENSBURG. I SIMPLY SHOULD NOT HAVE GONE WITH RPTED CONDITIONS, EVEN THOUGH I HAD NOT EXPERIENCED ICING ON THE EARLIER FLT.
