Thanks. I’ll try to make some more videos sometime.

[@loughkb]

My tr(u)sdx will probably be in the mailbox within the hour of me typing this. I was working on a portable paddle design, but the one you showed is just about perfect. I guess I'll just have to make a small USB rig interface custom for the radio instead. 🙂 Clever EFHW too. I like building it around the connector like that.

[@thekhakihat3233]

Thanks Kevin. I’m honored that you watched. I’ve learned a lot from you in your videos. You can contact Adam K6ARK for info on the paddles and the efhw kit at www.k6ark.com/

This is so cool, portable setup, and custom made from I what I can tell. Would be really useful in emergencies. I'm clueless on radio stuff, maybe I should get my licence and learn more about it. And custom electronics is also very interesting.

[@thekhakihat3233]

Have you gotten your license yet? It is a fascinating hobby. The radio isn’t custom though. The battery pack is just stuck on with double sided tape. Nothing fancy.

[@MrVertigo1971]

Great Video - very inspiring! Can I please ask for the name of that military pouch? Thank you.

[@thekhakihat3233]

The pouch is one I purchased from a friend several years ago, and I don’t see the exact same one on the maxpedition website. The M1 waistepack appears to be the most similar. www.maxpedition.com/collections/pouches/products/m-1-waistpack

[@vitogriffin8902]

I think that particular one was the anemone. As shown, it's perfect for this neat kit, and of course it's discontinued like all the good stuff. They make one similar called the pup that's very similar, but has Velcro instead of the buckle. There's plenty of similar models by other manufacturers. Blue falcon makes one really close.

[@pathopkins4500]

Hmmm even the same color .... hi hi hi =) I was pondering what bag or pack for it and looks like you might have a winner =) I have a Elecraft T-1 tuner and ZIP CORD dipole antennas / feedline for each band =) I use 8 - AA battery pack to feed my rig =) I like your idea 14500 Li ion though or even 18650's =) Good job on the setup =)

[@thekhakihat3233]

Thanks!

[@WillemLuntungan]

Nice portable radio +++

[@o2bnov0307]

This setup is my ideal portable unit. In my current job I travel at least 1wk/month. Being able to carry HF along would be amazing. So, this rig or the Venus SW-3B?

[@thekhakihat3233]

Just fwiw… I just did my first cw pota activation with this rig. It was working fine when I ended. When I got the radio out the next morning it will not transmit. Not sure what’s going on yet.

[@o2bnov0307]

@@thekhakihat3233 Oh no! I hope you get your radio back on the air soon.

Update... its working fine now. I think I may have had it in usb mode or something stupid like that.

[@leobismarck]

I was thinking if the combined 14,8v might be a bit high for the finals of this trx? Could you share some more experience if the radio is holding up fine when running it with the 4xbattery pack? tnx es vy 73 de Leo DL2COM

Nice set up mate. Do you have a video that covers making your antenna?

[@thekhakihat3233]

I don’t. This is the K6ARK antenna kit… he has a video where he shows how to build it. Thanks for watching.

[@SMB_SpeedTwin]

Thanks for the reply. Did you get the QRP or 20w Kit?

[@thekhakihat3233]

@@SMB_SpeedTwin it was the 10w/qrp kit

[@SMB_SpeedTwin]

What power supply are you using? Is that the DL1DN designed option? I fitted the DL2MAN one yesterday and it’s just too bulky takes away from the ease of pack up and transport.

[@thekhakihat3233]

The battery holder shown here is a 4 x 14500 cell stuck to the end of the trusdx with double sided foam mounting tape. It covers up the PA and USB ports, which I never use. It provides about 16v to the radio which makes some people uncomfortable. Now I mostly use 3 x 18650 cell holders secured to the back of the radio with heavy duty Velcro. I detach the battery to pack up the radio.

[@JimmyBaevsky]

I like your voiceless video Mr Hkaki Hat, Sir.

[@vlad-st]

Is this a 4s linion battery? Did you have any problems with voltage being too high, or is ok to run it with a 4s in your experience?

[@thekhakihat3233]

Yes, this is a 4s li ion battery. The radio will work with this voltage as long as the antenna has a low swr. I have since changed to a 3s battery to give me more wiggle room. Thanks for watching.

[@nine7295]

I think you can use LiFePo4 cells then it's 3.2 V per cell instead.

[@ke4est]

Man, I got to get me one of these. Been putting it off.

[@thekhakihat3233]

Have you gotten one yet? They are handy to have in the bag for an EDC radio.

[@iamsoulcandy]

Wow that’s a tiny setup! What is the farthest transmit and receive from that setup?

[@thekhakihat3233]

Hello soul candy. I believe I have been able to contact France from a SOTA summit in Virginia on 20m cw. It is a very capable rig. I usually pursue more regional contacts on 40m though. I have done multiple POTA and SOTA activations with this rig on voice and cw. It’s not fancy, but it works. 73 - AA4K

[@thekhakihat3233]

A shortwave radio for listening is not terribly expensive… but you get what you pay for. There are several online resources for learning Morse code (CW). I am using LCWO.net. There are also phone apps. A local radio club may also help.

[@stephane-710]

Very nice vidéo. Did you not check your SWR before starting to transmit? Which SWR value do you reach with this LW? Thanks . Stéphane. FR.

[@thekhakihat3233]

Thanks Stephane. At the time of recording this video my impression was that the antenna was fairly reliable so I didn’t always checked swr before transmitting. I have had a few problems with it lately, so I do check it routinely now. I usually get swr less than 1.5:1 depending on how I set up the antenna. Usually just varying the height of the matching unit above the ground has a significant effect on swr.
