I might be back near London next week for the first time this year and get an updated scan as for 108 why even bother it hasn't been able to exist for more than a few days whoever it is that tries to come on?
I picked up something on 108.0 a couple of weeks ago on a Sunday playing drum and bass, audio was in and out, buzzing crackling etc sounded like they were testing, it had RDS "_WK-END_"
