Allowing the rotor flow to work via bearing on QRZ?


 

Folks,
I’ve got the rotor flow designed by Dave wo2x, and it works well when I enter a degree heading, and turn the rotor to what is specified. However, I’d like to find a way to implement something that would allow that rotor flow to go out to QRZ look up a callsign, and turn my beam based on the callsign’s bearing from my 4th I’m assuming that’s possible?
Thanks.


 

Hi Justin

I have done exactly that with the rotor flow you have using N3FJP AC Log. When rotor flow is in tracking mode it can receive azimuth from AC Log. Also there is a callsign window in the rotor flow. Enter call and hit return. It sends call to AC Log which does call lookup. aC Log returns azimuth. Then when QSO is complete there is a log contact button in the flow. It logs the contact in AC Log.

This can be adapted to any logging program that has appropriate API interface.

Justin,

I'm wanting this as well. I've been thinking about the most generic way to implement it and still unsure. We all run different logging programs so that makes it tricky. For instance, I'm using HRD and I'm not sure that Dave's flow would work.?


 

Attached is a simple flow to enter a call sign, and to return bearing and distance. ? It does a lookup from hamdb.ord, and uses the lookup to calculate bearing and distance. ?No account setup is necessary.

You would need to check two things from HRD.?

1. If they have a command you can send to HRD (PC’s IP and a port number with a call to request QRZ lookup.?
2. If HRD can broadcast out an azimuth for a QRZ lookup.?

If the answer is yes to both then it should be easy to modify my rotor flow.?

I use smart SDR for Mac for my flex, and TS-control for my Kenwood ts-890, both written by the same author, and in my perfect world, I’d like to use Dave’s flow to manually enter a callsign, have it find out the bearing of the callsign from my location turn the rotor toward that heading, and then I’ll log it manually. ?I just can’t work out how to get that flow to talk to this app that resides on either my MacBook Pro, or MacBook Air depending on whether I’m traveling or not. ?I do have Tailscale working, and wow, what a neat way to access your flows when you are away from the shack. ?

Alan,

Does Hamdb use actual AZ or center of country? N1MM+ uses center of country.?

I could incorporate your Hamdb flow into the RT21 flow so you would have the option of manual or tracking for rotor. That way you don’t always have antennas turn on every lookup.?

Dave and all
?
Hamlib only returns lat and lng, ?I included bearing and distance functions on the flow for the calculations using QTH coordinates..
?
Hamlib only has US and Canadian Call signs. ? I am working now and a country centerline to centerline function.
?
Alan


 

I have revised the call sign to distance / bearing flow.
?
HamDB only has QTH coordinates for US and Canadian call signs.
?
So....
?
I added a function that will find the country lat/lng for the Call Sign's prefix, using a look up table. ?I then use the bearing and distance functions to calculate bearing and distance from your QTH to the centerline of the non us or non-conada ?country.
?
The flow will present the results of either HamDB, if the country is US or Canadat (QTH to QTH) , or Call sign country centerline from your QTH, if not US or Canada.

HI lan,
Could I get your help to install this in to my dashboard?

Thanks,
