TOPIC:

I've set up the azimuth reader on its own for use in a VHF rover operation. It works perfectly and should let me know exactly where my antenna is pointing no matter the direction of the car. I would like to change the background image. I'm considering a compass rose rather than world map.

I see that a right click on the app says "do you want to load new background image." Are there file size (pixels), shape (number pixels x number pixels), and file type specifications that I should take into consideration? Thanks for any insight you can provide. 73, Jim, K5ND

Dear Jim,

I know the app was designed with this map generation site in mind: ns6t.net/azimuth/

But I can't tell you exact size of the image - I am pretty sure that as long as you get the scale about right you should be fine.
It will resize the image to fit the window.

Hi Dragisa,

Thanks for your response and further direction. The map generating site looks very interesting. It should keep me occupied finding just the right map for my VHF work. I'll update my results later. BTW - you can find my blog post on the sensor at this link Pointing Rover Antennas -- 4O3A Magnetic Azimuth Sensor

Thanks again for your help and the great product.

Dear Jim,

Wow, nice, thanks for the link! Very glad you like our product!
Don't want to jinx it but we got some software improvements incoming for it as well.

p.s. Love your article, very well written!
Do you mind if we share it on our 4O3A Signature Facebook page?

Thank you for your kind words. Please feel free to share my article to your Facebook page.

I will update you on my map results later and update the blog post.

I look forward to the improvements you're planning for the sensor.

Have a great day,

Jim, K5ND

That was easy. I used the website you suggested for maps. That worked great. Since I'm operating VHF, I selected a map of just the USA. Your app is looking for a PNG file. So that's what I provided. It looks great and I'm sure I'll be making a few adjustments. I've updated my blog post and attached a photo here.

Thanks so much for your help.
