Hello,
these rigs are attracting the interest as I can see in many forums.
It is true that its price is very affordable but bear in mind they lack from a technical service support, and the quality is arguable. They are sent even without a manual, although you can find some guidance on internet.
Here and there there is a ramp up of information, comments and videos.
Just to make it clear there are two different models:
-
Model A: mainly advertised as the uSDR, is the basic 80 to 10 m transceiver, with a small speaker microphone. Weight is about 400 gram.
-
Model B: mainly advertised as the uSDX, is a 80-10 m variant (despite many wrongly post it as being a 160 - 6m transceiver) with built-in battery (12,6 V 5000 mAh) and a built in microphone in the chassis. Weight is about 690 gram (similar to a KX3, but not the same thing!).
Some of the adverts say it is a 10w battery, but they seem exagerated.
These are power output values extracted from the video of DL1DN for Model B:
Output power (approximate):
- Test 1: Internal battery
6W 80m
6W 60m
5.8W 40m
4W 30m
5W 20m
3.5W 17m
3.5W 15m
1,8W 12m
2W 10m
- Test 2: 13.8V external supply
8W 80m
8W 60m
7W 40m
5W 30m
6W 20m
4.5W 17m
4.5W 15m
2W 12m
2.5W 10m
RX current drain is 80 mAmp.
TX current drain about 900 mAmp.
I would say this is a QRP rig (5w) in the most frequent SOTA bands, and reduced power in the higher frequencies.
It is interesting to look at how it looks like inside (component solder quality), and also to see
the comments in the video concerning some bugs.
Dealing with settings of the rig via a single Menu button is not very friendly, moreover when you are exposed out in the wild!
Anyway, maybe it is a nice rig for a newbie that just wants to get the taste of being portable.
Stay tuned to read more of them in the coming weeks, as users publish some feedback.
