Narrative:
On departure; the nose gear had an unsafe red light when the gear was retracted; with a lot of air noise. We asked ATC to level us at 3000 ft. ATC asked if we needed assistance. I decided not to declare an emergency. My plan was to possibly work out the problem and then continue to our destination. The autoplt failed to engage. We then lost cabin altitude at 3000 ft. First officer was able to regain it briefly before it was lost again. A few caution lights also illuminated. The flight attendants reported a constant chiming in the cabin which was very noticeable in the cockpit. I elected not to recycle the landing gear due to previous write-ups on the nose gear. TRACON offered us a right base for a landing. We got normal green indications on the landing gear when it was lowered. I felt that the safest decision would be to land the aircraft as soon as possible. I landed 1200 pounds overweight. We were so busy that I forgot to declare an emergency for the overweight landing. I did enter the overweight landing in the logbook after gate arrival.

Title: AN MD-80 FLT CREW EXPERIENCED RED LNDG GEAR UNSAFE LIGHT AFTER TAKEOFF; ACCOMPANIED BY LOSS OF CABIN PRESSURE. AFTER EXTENSION; LNDG GEAR SHOWED THREE GREEN. THEY RETURNED TO DEP ARPT AND LANDED.
Narrative: ON DEP; THE NOSE GEAR HAD AN UNSAFE RED LIGHT WHEN THE GEAR WAS RETRACTED; WITH A LOT OF AIR NOISE. WE ASKED ATC TO LEVEL US AT 3000 FT. ATC ASKED IF WE NEEDED ASSISTANCE. I DECIDED NOT TO DECLARE AN EMER. MY PLAN WAS TO POSSIBLY WORK OUT THE PROB AND THEN CONTINUE TO OUR DEST. THE AUTOPLT FAILED TO ENGAGE. WE THEN LOST CABIN ALT AT 3000 FT. FO WAS ABLE TO REGAIN IT BRIEFLY BEFORE IT WAS LOST AGAIN. A FEW CAUTION LIGHTS ALSO ILLUMINATED. THE FLT ATTENDANTS RPTED A CONSTANT CHIMING IN THE CABIN WHICH WAS VERY NOTICEABLE IN THE COCKPIT. I ELECTED NOT TO RECYCLE THE LNDG GEAR DUE TO PREVIOUS WRITE-UPS ON THE NOSE GEAR. TRACON OFFERED US A R BASE FOR A LNDG. WE GOT NORMAL GREEN INDICATIONS ON THE LNDG GEAR WHEN IT WAS LOWERED. I FELT THAT THE SAFEST DECISION WOULD BE TO LAND THE ACFT ASAP. I LANDED 1200 LBS OVERWT. WE WERE SO BUSY THAT I FORGOT TO DECLARE AN EMER FOR THE OVERWT LNDG. I DID ENTER THE OVERWT LNDG IN THE LOGBOOK AFTER GATE ARR.
