FYI this was the last summer you will see RMV in the CW beacon form.Past its use by date.
To this end I am attempting with difficulty to establishing a wspr beacon on 293 the RMV allocation.
RMV and RMH are in the way f wspr users.
I have a TS680S like Lloyd FP uses on VK4TVL.
I am waiting on an interface and RS232 module.
I thought I had internet access at Dundas but it has been firewalled so I haven't any way of getting a time sync unless someone can tell me how to do it on a shoestring using a prepaid mobile and I mean cheap.
the beacon could run 10 years, and as in past I have never nor will get financial assistance, and not asking for it, but I don't need a $500 a year account either.
so I am open to ideas.
A dedicated exciter.
Time syncing, how can it be done without internet?

Re: VK3RMV beacon
Hi Steve,
On my Albany remote station I'm using iiNet 3G service (wholesale carrier is Optus).
See: http://www.iinet.net.au/internet/broadband/mobile/
I am on the 4GB/month broadband plan and as I'm already an iiNet customer, I get a $5/mth discount off the advertised price ($14.95/mth). No contract, month to month only.
If you are onlyuploading WSPR spots and time syncing, I'm guessing you would use that much data at all in a month, so maybe you could get by with 2GB/month and if you're a customer of iiNet or one of their subsidiaries, this will cost you $9.95/month.
With iiNet you also get a public IP, so you can remotely access your equipment at the remote end via the internet if required.
Equipment wise, I purchased a Dovado Tiny 3G/Wifi router and Sierra Wireless 320U Aircard 3G/4G USB dongle from Telco Antennas in Brisbane, which cost around $230.00 all up.

Hope this helps.

Possibly through GPS? http://wsprnet.org/drupal/node/2708VK3ZAZ wrote: Time syncing, how can it be done without internet?
W3PM has done it with WWVB but we're outside its coverage http://www.knology.net/~gmarcus/
PS: VK3RMV on 6m has been appreciated. It's always the first frequency I tune to when on 6m and the most reliable signal heard. It's usually copiable at water level with either the 40cm ped mobile loop or end-fed wire.

I haven't used C# to write to the windows clock but that shouldn't be insurmountable.
If you don't have an IDE a reasonable free one is - http://www.icsharpcode.net/OpenSource/SD/
Have fun

You haven't said if you are running a computer to generate the WSPR, and what type.VK3ZAZ wrote: Time syncing, how can it be done without internet?
There are ports of xntp to Linux and WIndows, and it contained an interface module for NMEA from a GPS decades ago. At the time, consumer GPS had terrible jitter on the NMEA output, but it would have been plenty good enough for the task you have in mind. I suspect the modern xntp daemon can read both NMEA sentences and PPS clock, and you can by a GPS module that delivers those for about $20 (I have some on my UAVs).

Check out the IZ2BKT time sync prog. can sync. from gpsTime syncing, how can it be done without internet?

Certainly the easiest to get going in a Win7 environment. and quite stable here.VK4BLK wrote:Check out the IZ2BKT time sync prog. can sync. from gpsTime syncing, how can it be done without internet?
