I've been monitoring the 8m band recently (yes, 8m!). It's generally an ISM band with some experimental licenses issued in the US, Canada, and other countries, as well as a few amateur allocations in Europe. Some great propagation happening today between Australia/NZ and USA/Canada, on 40.68 MHz.

Also, a very good signal here from VA2CY up on Île d'Orléans QC, with apparent doppler shift due to the movement of Sporadic E clouds between our stations. If you look closely at the top, there's a very weak trace from another station with some aircraft scatter (no decode). I think that is WM2XCW in Point Roberts,BC near the Canada/US border. ETA: confirmed this is not doppler shift, it's transmitter drift.

@vk6flab They will show up if they are just listening, which is the case here. It's valid for people with the right experimental license, and possibly at very low levels within Australian ISM rules (I'm more up to date on the US rules here and it is in the microwatt range on these frequencies).

@vk6flab I don't see it listed in the ACMA database. Could be a made up callsign for rx only.

@vk6flab That is bananas. I've been out of .au for a few years now so didn't know this. All of the VH5A* entries in ACMA are for commercial or govt users in SA. One close callsign is the Bureau of Meteorology, so I was wondering if it was them monitoring for space weather.

@vk6flab Look at the footnotes, especially 150. Why this is not called out explicitly in the national regs is unclear (FCC does the same here -- you need an army of lawyers for this stuff).
