Hi ssfahrer! The NF list is developed from observed frequency changes here in Melbourne from the start of the B13 transmission period at the end of October. Only
changes to frequency or station operation are noted on this list. Re. 3215 - in the time period that we can listen to the 90mb in our evenings from 1000 to around 2000 (it's the start of summer here), I noted no new frequency changes. 3215 does make it here but not regularly, the best time being our winter or when thunderstorm noise is lower. Re. 4840, this is heard regularly in the evenings, but cops a lot of splash from ABC Alice Springs on 4835. Again, no frequency changes were noted here.
Yes, the tropical bands do exist here also.
And as evidence of that, I noted a frequency change only this last weekend for 3965 - Iran from Kamalabad at 1745 (4:45am EDST), as listed in my recent blog post

And, as you asked, also as evidence of shortwave activity on the 90-60mb, can I suggest you check out my survey of LA stations observed during our last winter period? While the Latins are much easier for you guys in the States, but they present a real challenge for us Aussies. You'll find it at
