Hi Vlad,

I have two requests and one question.
For about 40 years I'm a member of the VHF and up contestclub PI4GN. We contest on 144 (as PA1T) and 70 cm up to 24 GHz as PI4GN. 

At home I have the possibility to also transmit on many VHF and up nands and like to SDC for it. So I made a contest called VHFREG1 for it in SDC which is attached to this e-mail.
Using a call history at the moment from the N1MM website (as I'm on vacation now and can;t access our better database we use during the contests).

Request 1
- the program shows the distance to a contest station (between 6 digit locators) on screen left from the bands.
Request to add antenna direction based on GRID6 locators also n screen (not to country as it shows above in the screen). Then we know where to direct the antenna to when the qso is difficult.

Example:    PA1M: JO33GE     PA1T: JO33HF
Shown is the distance: 17 (km) - Between Auto and 50.0
Now shown: 216 degrees (SSW) - above in the New QSO1 window but that is between countries
Please add between the two grids: 44 degrees (NE)

Proposal: add the direction to the station under the distance already shown before the bands on screen?

Request 2
- add more bands, now up to 23 cm. Also add up to 24 GHz.
  13cm      9cm      6cm       3cm      1,5 cm
  2,4 GHz  3,4 GHz   6,8 GHz  10 GHz   24 GHz

Or canI do that myself?

Question
The lower left of the QSO window shows stations from the callhistory file but also it shows stations not in it (and not having a grid).
Where does this info come from?

PA1TO is in the list but has no grid.

Kind regards,

Hi Thomas
Your suggestions are interesting, I will try to implement them. I don't think it will be difficult.

The lower left of the QSO window shows stations from the callhistory file but also it shows stations not in it (and not having a grid).
Where does this info come from?

This list is generated based on the Master.dta file. See the "Cluster" tab.
