[Lowfer] VLF ... VTX3 on 18.2 kHz

[Dave Brown]

Used to hear VTX3 (from India)  all the time on 18.2 (or was it 18.1?) with 
mostly machine morse ID,  interrupted regularly with hand sent 5 letter 
groups and other such stuff. It disappeared  several years ago and not heard 
it since-although not been able to listen for last 2 years- shack still 
recovering from quake damage.
