Hi Mark,

Are the frequencies quoted dial frequency or centre frequency?

My 40m gateway is on (dial) 7.049110 LSB. I'm using a modified AEA PK232MBX so my tone pair is still 2110/2310Hz so the centre frequency is 7.048600

As far as I'm aware there's only two other 40m gateways,

40m 7048.600kHz LSB
VK2IO-4 Sydney Primary Net Station (also 7.047.17 LSB)
VK7HSE-4 Kingston Secondary Net Station

The old frequency used to be centred on 7.036 but with the band plan changes several years ago the decision was to made to move to the current frequency.

Hi all,

I'm now running receive-only HF APRS iGates at the AREG low-noise remote HF Receive site, which is north of Adelaide. The antenna is a broadband conical monopole. The callsign is currently VK5QI-3.

The receivers are sitting on:
30m: 10147.6 kHz USB
40m: 7045.2 kHz USB

These iGates are using direwolf, which is hooked into the Airspy HF SpyServers which are running up at the site. This allows the receivers to be shared amongst many clients, of which the HF APRS decoder is one.

Information on the scripts I'm using to run this is available here: https://gist.github.com/darksidelemm/6b60767714295962771bca7b728b343c

The 30m iGate has been running for a while, and has seen stations as far away as Europe.
