HAM Radio logo

I'm looking for a new HAM radio logo. Free to submit your ideas, the radio station will operate worldwide and in HF VHF UHF SHF bands. It should also include the Swiss banner. The station name are two letters followed by one number and three more letters. For discretion the callsigh name is not published, but it's like AB4ABC.
The best is you search to "Amateur Radio logo" to see what already exist. Off course I ask a unique design (not a copy from another).
What I'm looking is below but not mandatory
- Perspective effect
- World map in background
- Self explicit logo
- Off course beautiful and unique

Please send mockup to let's me choose from all propositions. I don't want your portofolio I expecting the design of my logo.

This job can earn more designs for others callsign if it's well done.

Budget is limited but it's my budget for this work
