Michael G0POT reviews the Go4Lo
Customer feedback "I was surprised at the accuracy of the power measurement, with the change in indicated power taking place within a fraction of a watt as indicated on my 2955 test set. I was able to test the SWR indication at 2:1 and 3:1 and it gave the expected indication.
A very good addition to my portable set-up!" Tony August 2016

The Go4Lo II is a unique SWR bridge with built in power indicator. It is designed for home or field use in situations where the operator wants to concentrate on tasks other than looking at a conventional SWR meter.
The Go4Lo is battery powered; a tap of the single control button wakes up its microcontroller. The main feedback from the Go4Lo II is audible. SWR is indicated by both the frequency of the tone and the number of bleeps per second. The tone frequency drops as the SWR approaches a VSWR of 1:1; above 10:1 a constant tone is sounded. An SWR LED flashes at the same rate as the tone bleeps too! Once you have finished using your Go4Low II, it automatically goes back to sleep to conserve battery life.
A power indicator shows the power range:
The transition at 5 Watts allows QRPers to accurately set their power to be within the standard QRP range.
An overload warning sounds if the power exceeds 115 Watts.
SWR and power are measured using the popular and well respected Tandem-Match circuit.
The Go4Lo II is powered from a single 9 Volt battery (not included). The expected battery life exceeds 1 year due to the low-current design. Naturally, we have built in a low battery warning indicator to give you time to get a new battery.
The Go4Lo II kit is supplied in two forms.
The Go4Lo II is also a great tool for radio users with impaired eyesight - why not build one for a friend?
Note: the Go4Lo II requires a steady carrier for optimum performance.
Dont forget our range of patch leads that will be perfect for your Go4Lo II!

Another decent kit from Richard. It is straight forward to build but care must be taken when preparing the mini coax. Some of the solder pads are rather small too. Alignment is easy and carried out with a multimeter. As I'm QRP, I haven't tested it at 100W yet otherwise it does everything claimed of it.
I recommend this kit.

I am a blind ham. I had a sighted ham build this kit. It is perfect for the blind op. 1:1 swr is indicated by slow low beeps, the faster and higher the beeps, the higher the SWR.
My only suggestion is that Richard offer a service to build the kits for blind folk who can't. Thanks for an excellent product! It is the only one available for the blind at the moment.

yet another excellent product from sota beams very pleased with it and well documented and so easy to build and use on my first outing into the ooloo worked all round Europe on 4 watts and to put the icing on the cake got 559 from Brazil and highly recommended. Well done to the sota team makes my mountain tuner even easier to tune

Very pleased with the Go4Lo II, the beeps make the adjustment of my mountain tuner much easier. An enjoyable kit to build, it took a couple of hours on a rainy afternoon. I opted for the enclosure kit, this finishes it off nicely and holds the battery in fairly securely. I found the most time consuming part to be trimming and fitting the coax coupling through T1 and T2. Alignment requires nothing more than a transceiver, 50 ohm dummy load and a digital volt meter. Seems accurate - it agrees entirely with my transceiver's built in SWR meter on all the HF bands I've operated.
