Polytone station [XPH]

Can anyone tell me when the first polytone station appeared? I found a recording from 1981 in my collection, so they are there for at least 17 years!

XPH hunter Andy Bell discovered that XPH not only changed their usual frequencies in November, but also one of the transmission days.

XPH's morning schedules are now on Tuesdays and Fridays - they were on Wednesdays and Fridays. Obvious frequency ID of 215. XPH also changed their time slot to winter time.

Apparently something went wrong as the first November transmissions were on the October frequencies. They eventually changed to a new set of frequencies.

November morning skeds:
07.00 UTC - 11634 kHz
07.20 UTC - 12434 kHz
07.40 UTC - 14834 kHz

Andy sez "I wonder if the station manager read his Spooks mail and realised they hadn't changed frequencies"

Andy continues.... "tuned in for XPH this morning (Tue, 17 Nov 98) on the November frequencies. However the 0720z transmission went out on 13434 kHz and not 12434 kHz as expected."
