The Polar Explorer – A High-Efficiency Transmitter

Thanks for your interest in The Polar Explorer! Although I am diligently continuing development on the Polar Explorer, it is not yet ready for beta testing or release for sale. My main interest in this project is to bring this new technology to the Ham market. However, I want to make sure the technology is received well and not tainted by shortcomings in my particular implementation. Therefore I'm continuing to work to give it the best possible reception by Ham users.



Thanks for your patience – watch this space for future news updates on the Polar Explorer!

Any idea what the release date will be?
I signed up for beta testing.

@K1KP Inquiring minds want to know.

 

It's hard to believe its been over a year since our trip to Dayton. In that time I have continued to study this new technology as my full time vocation, filling up another 250 pages of lab notebooks. Although I have closed the list of beta testers (I have more than I can support), I do have your information on file Bob and will be in touch when it's time to start beta.

Thanks for your continued interest,

-Tony, K1KP

 

He asked, "Any idea what the release date will be?"
Seems like a valid question under the circumstances.

 

Update!

I’m pleased to announce that Polar Explorer technology has been integrated into the latest FlexRadio product, the Aurora series radios. This is the result of a 6-year collaboration with FlexRadio to develop the product, and explains why the Polar Explorer website (polex-tech.com) has not been updated since 2019. Development of the Polar Explorer as a standalone transmitter was discontinued when work on Aurora began.

I invite you to visit the FlexRadio website for all the details at https://www.flexradio.com/aurora

I knew it! As soon as I saw the specs/features of the Flex Aurora, I said to myself, "This is the Polar Explorer!"
Great to see the technology becoming a commercial product.

Congratulations to you Tony, and everyone else who worked on the Polar Explorer!

Updating old house wiring for a 500 watt amp, what does this mean?

I have my own version of K4XU's original 575 watt Microsemi VRF2933 P-P VDMOS amp built around 1995 that has been running off of regular 120V service for 30 years.

This amp was similar to the the later KPA500 amp design and never in the past 30 years have I had to update my house wiring for this amp and I doubt that the KPA500 would have any issues running off of any 120 volt service.

I'm have been using this amp at 4 different QTH's from the boonies of Prescott, Arizona, Olathe Ks., Phoeniz Az and Salem, Or., all on standard 120 volt service with no mods required to any of my house wiring.

In his original Microsemi dev amp, as I remember Dick, KX4U, was measuring around 68 % efficiency after the LPF and T/R switch.

Oh yeah after looking at the Flex price and the added value and my ROI which is minimal if any, I still prefer the TANSCEIVERS anyday.
