Joe and all. Curious because I am not a big contester. My understanding is the 
reason for the extra coding is for producing the message sent for TX3 with both 
calls plus R Grid. If it’s a problem with extra characters involved, why can't 
you just condense the standard message to send a single call of the station you 
are working with R Grid? Wouldn’t this save the effort of having to use extra 
coding in the software for converting an odd ball grid to something that makes 
sense? Then no matter if you are in contest mode or not, everyone would see the 
same message.

Example:

Current TX3 message in contest mode:  K1JT KA9CFD R EN40

Replace TX3 message transmitted by KA9CFD:  K1JT R EN40

Rational: A CQ with one call has already been sent, and response has been 
received with both calls and a grid by the time TX3 is ready to be sent.

Thanks again for an amazing piece of software.

On a side note, I received for the first time this morning a VK4 on 630m WSPR 
just right before my Sunrise. Wow! I was wondering if any plans are coming to 
continue work on a WSPR-LF mode that I saw in the spring before the FT8 craze. 😊

Subject: [wsjt-devel] NA VHF Contest Mode

Hi all,

As an experiment, code revision r8101 in the WSJT-X development branch includes 
several changes to the way *NA VHF Contest Mode* is implemented.  The goal is 
to obviate any cause for confusion (e.g., implausible grid squares being 
diaplayed) when one station uses Contest Mode and the QSO partner does not.

Here are a few details.

1. First, remember that NA VHF Contest Mode applies only to the FT8 and
MSK144 protocols, where speed in completing a minimal QSO is especially 
important.  (Of course, you can also make contest QSOs using JT4, JT9, JT65, or 
QRA64, but they generally take longer.)

2. The checkbox to activate Contest Mode has been moved from the *Settings -> 
Advanced* tab to the main screen.

3. If you're operating in FT8 or MSK144 mode on a VHF+ band and the locator in 
a decoded message seems to imply a distance greater than
10,000 km, the program will prompt you to activate Contest Mode.

   - Click *YES* if you're making a contest QSO but forgot to activate
     Contest Mode.

   - Click NO if you really are luck enough to be working a JA, VK, or
     whatever.

The program will prompt you only once.

If you are interested in VHF contesting and able to build WSJT-X for yourself, 
please give it a try and report your findings here.
