Ah, the Ol’ (new) MTR3b! Loved the way a POTA can be pounced on… I don’t think I could manage a Pile Up. I just don’t… Any hooo, I did notice the N6ARA Tiny SWR… I first saw one a weekor so back on a QRPer guest post, and right then ordered one. I’ve been tracking it’s arrival, and it arrives today! Great video Thomas! 72 de W7UDT
I keep all my spare 9v batts in a plastic box I 'm old school and cheap! I just put a piece of black tape across the terminals so they don't short out on each other so far 50 yrs no shorts!. missed you on this one Thomas. and Joshua, looks like you both had good time will keep on huntin! 73 agn ed Ellis WA1RKS
great job Thomas. I stumbled across some rechargebles 9v's as well that I use for powering one of my RX aerials on MW it helps to cut down the noise from wall warts! and they also get used with my MTR4b that I take away with me to listen to the bands on holiday . 73's Nick G8SYE
I have one suggestion, Thomas: Get a couple of caps for those 9V batteries. You don't want those to short against the terminals as they can do quite a current dump and generate a lot of heat. I keep my 9V batteries in a storage box with a lid (a compartment for each battery) to avoid anything coming into contact with the terminals. Fun video. I'm glad to see a younger guy learning code. 73 de AG7TX
This is another great K4SWL video! The small SWR indicator is really cool. But, keep in mind that resistive bridges tell only part of the SWR story. RF impedance is composed of both resistance and either inductive or capacitive reactance (which can be any value including zero). The little LED SWR bridges do not indicate the degree of mismatch resulting from said reactance.
Thomas thanks for the information on the 9v lithium and the swr meter. Great stocking stuffers from the wife. Not sure if you are familiar with the QRPGuys LED Tuning Indicator. Also an SWR meter for qrp. This model thas an absortion bridge built in preventing damaging your radio with high swr antenna while in tuning mode. You can also use this feature to limit for TX output from 5 to 1 Watt. Even better than that is the tiny swr/power meter. LY2H has a video on."The best ham radio accessory I wanted for my QCX/QDX transceivers!" Size of a match box digital meter rated for 0.1 to 11watts from 80m to 10m. Keep up the great work. Don't change a thing.
Oops! After looking at the K6ARA SWR indicator manual, I see that it is not a resistive bridge. Great! So my previous comments do not apply to that well designed device! Many other LED SWR indicators such as in the ZM-2 ATU do have the shortcoming of not being able to indicate true SWR.
At 9V the MTR3B puts out 3 watts max. It has 650 mAhr available. Tha average consumption operaring at 9V is about 260 mA. The operating time would be about 2.5 hrs. My experience confirms that 2 hrs is easy to obtain, but I have never run the batteries completely dead.

Truly impressive. Less than 30 minutes ! Wowsers !

You'll love that Mini SWR meter, Rand!

Yes, a very good suggestion! I might 3D print some.

Gm Tom hope you and family had an awesome tnx gvng
We did. I hope you did too!

was the speaker ok? thank you for the video.
Oh yes, the soundcore is a great one!
How long can you operate that battery with 10 watts?
At 9V the MTR3B puts out 3 watts max. It has 650 mAhr available. Tha average consumption operaring at 9V is about 260 mA. The operating time would be about 2.5 hrs. My experience confirms that 2 hrs is easy to obtain, but I have never run the batteries completely dead.
