Yes, that is correct. It uses a non-resonant design to acheive a brad band match. That does mean that it needs an external ATU to access all the bands as most internal transceiver ATUs don't have sufficient range, especially at 40m and 30m where the performance is more of a compromise than for 10m.

Hi, The 40/30M setup for the I-Pro Traveller is quite sensitive to position relative to ground, especially if the ground is wet. Raising it up can help a lot. Glad you found the video useful.

The element tubes are all 2.5m long so that is the length of the package for shipping. The main element comprises 2 of these tubes so that is 5m long.

Yes, very true. I have now built a new decoder using the ESP32 and new algorityms which is better at decoding hand keyed CW. It also includes a practice mode to analyse your timing accuracy.

Hi Alexander, Yes, I'll look at posting links to the source files. Currently working on an ESP32 version of the decoder and will also put some info up about that when I get chance. Kind regards, Tony

Hi, the I-Pro Traveller weighs about 7kg. You can find more details on the website: www.proantennas.co.uk/i-pro-traveller

@@proantennas Tx!

Agreed.

Hi Gregory, Orienting the capacity hats vertically will unbalance the system and reduce the effective height above ground. Performance changes will be subtle but one noticeable change is usually an increase in the noise floor that will reduce signal to noise performance on receive. Kind regards, Tony

Hi, thanks for the contact. The maximum power is 1000W PEP on 10m and yes, it should also work well on 11m.

Thanks Andrew

Hi Tim, thanks for the comment. Let me know if you have any questions.

Hi, thanks for your comment. Yes, it took some time to implement it on the Arduino but I am very pleased with the result. There is a lot more detail in my website whats new section: www.proantennas.co.uk/blog I am still tweaking the software and will adding another update soon. Happy to share the code with anyone who is interested.

Hi, Thanks for the comment. I have to update it now as I have changed the matching transformer mounting arrangement. Hope you are staying safe in India.

@@proantennas QSL thanks very much, stay safe 73

Hi Arnie, There is a lot of information on the Pro Antennas website in the what's new blog section: www.proantennas.co.uk/blog I am not quite finished with the code yet but will publish the sketches when it is ready - don't hold your breath, it has taken me 9 months to get this far! I don't think I have published component values on the schematics either but I can do that shortly. If you would like these in the current state, ahead of publication, contact me via the website and I will send them to you as is. Kind regards, Tony

@@proantennas Thanks! Great work so far. Yours is the first sketch I have seen that uses an adaptable Goertzel frequency to decode CW. The other sketches that use the Goertzel algorithm that I have seen all use a fixed audio frequency for decoding.

@@arniep740 Hi Arnie, Yes, that was the main challenge - finding a way to decide which audio frequency to focus on and then adapting the Goertzel calculations without creating floating point calculations that take far too long to process. With refinement, I'm hoping it will match the better PC based solutions but using a much lower powered processor.

Thanks for the feedback. I will take that into account in future vids

Hi Nigel, The Dual Beam Pro is more compact than a full size dipole and easier to mount at height. The smaller size coupled with the balancing matching transformer also means It has lower receive noise levels. The Dual Beam Pro is also directional with 2 lobes radiating at right angles to the main element. This gives a gain of up to 11dBi or around 8dB relative to a simple half wave dipole. I hope this helps. Kind regards, Tony

@@proantennas thank you for the reply one last question I have got a external atu but convinience of built in atu does make for a easy life generally speaking do you think the atu within my Yaesu ft950 would tune 20 to 10m many thanks

Hi Nigel, I can't guarantee it but you should be fine on 20-10m with most built in ATUs. The native SWR for these bands should be between 3:1 and 6:1. Kind regards Tony

Not to everyone's taste but I like it and it takes the edge of my commentary :-)

Thanks Hassan, glad you like it.

Thanks Paul. Get in touch via the website proantennas.co.uk if you have any questions.

Thanks Jeremy. Glad you found it useful. Hope you are getting on ok with your Dual Beam Pro.

Thanks for the comment - let me know if you want any information.
