I hope that's will not be a 'just install and use'  box. :-(


These kind of devices almost killed the spirit of amateur-radio. Thankfully the maker/hacker-community came to save us.

After I played with it, it's not to bad. I used the demo for droid and played the test files on Nvis.club and it works pretty slick. I think it will be a good challenge to go in the field with low power and see what it will do providing we can get some more operators using it.

As I wrote, destination ID is used only to select a station which can send acknowledge.

All station receive all messages.

If you send "CQ", good way is to send it to "0" ID.

Re: Need info on reliable refurbished computer source

Don Coker
 

I have bought two Dell OptiPlexes and one Dell Laptop, all renewed off of Amazon. Stuck with Dell because it is easy to get the drivers and other support info. Both OptiPlexes arrived and worked as represented. The Laptop would not boot, so got a return authorization that cost me nothing and a credit back in 10 days. Got another Laptop and it worked just fine.  Overall, I have been happy.

VE3GTC, Graham
 

have a look at Dell refurbished computers. These are computers that are only a few years old and back to DELL after being leased to some business or corporation:



good deals, good service in my experience.

Re: Need info on reliable refurbished computer source

Dave Corio
 

Andy, I'll give you first-hand info on Monday or Tuesday! XYL & I been doing business with Amazon for quite a few years and never had a problem. Looked closer, and all the reviews were at least 3 years old or more. Ended up ordering a refurb unit for $260 and should have it Monday.

Dell Optiplex 900
16G RAM
Intel quad core
3.1 GHz
1 Tb HDD
DVD drive
Wifi
Win 10 Pro (could be Home
10 USB ports

Maybe stupid of me, but I also got a 3-year warranty for an additional $35 in addtion to the 90-day Amazon warranty. Hate buying service contracts, but seemed like a good price for a piece of used equipment.

I have had good luck buying them off ebay.  Looked at the feedback and found the higher rated ones.  Over the last 10 to 15 years I have bought 5 or 6 and only have 2 that have failed.  They both ran many years and were only turned off to move them around from place to place.

Bo, OZ2M
 

Hello group

It might be me but I haven't been able to find out how to implement PS-18 from the links and information given here. I believe I have a good head start having implemented FSK441, FT8, ISCAT, JT4, JT6, JT65, JT9, MSK144, Opera (no official doc.!), PI4, T10, WSPR and QRA64. My general advise is to document the protocol in full and an easy to find page/location and/or open source to have a fair chance of being successful.

To show your amateur callsign, you need to include it to message.

Digital ID of your terminal is sent and shown automatically.


Good way is to include your callsign in the beacon message text as

#;N0CALL-12;Comment there

In this case any AprsGate which hears you
sends your beacon as "Position" packet (or Status packet, if GPS is off) with your N0CALL-12 callsign to APRS network.
