A nice QRP surprise this morning
We’re getting ready to hit the road for vacation. It’s been a whole year since KD2CHE and I tied the knot on a cliff overlooking Lake Tahoe.
We’re not going to be heading back there yet, but wandering through New York’s North Country a bit. I’m expecting to get a little portable QRP operation in as we poke around up there. In anticipation of the trip, I picked up a spare power supply from my brother a few weeks ago to use with the Xiegu X1M, and any other 12V items I have or may acquire when I’m not near my main setup. I decided to assemble the “motel room” version of my QRP setup here to see how it works. I have the Xiegu, my Emtech ZM2 tuner, mic, the spare PS, and a small amplified speaker sitting here on the couch. A string of 2 alligator leads is running from the ZM2 to the feed-thru from my random wire up near the window. Everything powered up, and tuned up, so I decided to answer a couple of calls on 15M.
I made USB contacts with UT7UJ in Kiev, and S51ZZ in Slovenia from my test station on the couch here in Long Island. Not bad for 5 Watts. This little rig is full of surprises. I also just found out from Ed at Import Communications through a post to the Xiegu X1M Yahoo group that he is going to be offering upgrade kits for the earlier X1M to upgrade the front panel and display to the newer version, as well as a strong possibility of a firmware upgrade that will cure many of this rig’s little issues. The firmware upgrade has already been released for the newer model.
Now, time to pack it back up, and hit the road. 73s de Neil, W2NDG
A weekend with the Xiegu X1M
So, I have now had the X1M since Friday. I have to say that overall, I like it. Friday night (as previously posted) I checked in to the
Brothers Net, and was heard clearly in Virginia, and again on Saturday night, when one of the members in Virginia relayed my check in to the operator in Maryland. Also on Saturday I logged 5 of the 7 Florida QSO Party spelling bee stations from my living room, as well as a couple of other Florida stations. Reports ranged from good for QRP, to Wow! Only 5 Watts? Keep in mind this is in a much-less-than-ideal setup.
In our apartment, KD2CHE and I are extremely limited on space, inside AND out. The X1M is attached to an L-shaped random wire in the front yard, by way of a Balun Designs 9:1 Unun, and an Emtech ZM2 tuner. Emtech recommends not using an additional balun or unun, but it seems to perform a little better with this crazy antenna.
It tunes up on most bands, and appears to tune up on 75, but signal reports were bad on 75, with a lot of RF feedback, and I can hear myself in the speakers I have attached to our TV when I transmit. 17 meters seems to be an issue with the TV speakers as well. I’d love to put up something better in the front yard, but we’ll see what the landlord and neighbors are willing to put up with. 160, by the way is a no-go, but I don’t think that’s a surprise.
I’ve gotten the hang of using the X1M pretty quickly. I haven’t used the memories yet, but I use the dual VFOs quite a bit, as well all of the different tuning speeds. Everything is fairly straight forward once you get the hang of it. Audio is what you would expect for a radio of this size (this thing is SMALL!), and fine through headphones. The receiver is very sensitive. I’ll get some actual numbers next weekend. I like that you can kill the display light to conserve batteries, which will help when portable.
I’ve tried battery power. With 8 alkaline AAs the radio seems to perform OK, however, 8 LiIon batteries are not quite enough voltage for the rig, producing some howls and distortion with the volume above about 40%. I guess I’m not too surprised at this, since 8 FULLY charged AA Eneloops only put out 9.6 volts. I will supplement that with 4 more Eneloops in series for a max of 14.4 volts. Later on, I can pick up something a little more sophisticated. I also made a coax-to-powerpole cable for mobile use, so I can always just set up next to the car when needed.
A coax power plug for making your own power cord, and a 1/8″ stereo (3 cond) plug for wiring to a key/paddle are included. The power connector is a very common size, 5.5mm OD x 2.1mm ID, or Radio Shack size M, which made powering the radio up easy, since I had a size M-to-tinned-leads cable already. I wired a straight-key up to the 1/8″ plug, and had to set the keyer mode to manual, which was also not hard to figure out. The instructions are in Chinese, but an English translated manual is available from Import Communications, or in the X1M Yahoo group.
I think the little X1M has a nice future in my collection. It’s no KX3, but for about $300, it’s a nice little radio.

The X1M Arrives!
I finally received my assembled Xiegu X1M today. I unpacked it and started tuning around before going out to dinner with the XYL, but after I got home I picked
up the mic and tried it out. Attached to an Emtech ZM2 tuner, and about 50-odd feet of random wire in the trees here, I checked in to the Brothers Net on 7192kHz. Not bad for 5 watts, and a less-than-ideal antenna. We’re off to a good start. More to follow.
X1M QRP SSB/CW Transceiver Kit
I’ve been watching this little thing for a few weeks. They showed up on the Kight Radio Store web page and after a few days, when I decided to pull the trigger, they had sold out. Today they are back in stock, and one of them is on its way to me (hopefully). Construction is described as easy assembly which I gather makes it similar to the KX3 kit. Here are the features and specs from Kight Radio:
Transceiver: X1M [v2.01]
Frequency range: 0.1 ~ 30mhz transceiver;
Modes: ssb / cw
Power output: 5 Watts (max);
Operating voltage: minimum 9.6v (dc), max 14.5v (dc);
Operating current: 0.35a (min), 1.2a (max);
Memory 100 channels ;
Automatic internal CW keyer
Keyboard can be locked;
Dimensions: 97 * 40 * 155 (mm)
Receiving sensitivity: better than 0.45uV
Frequency stability: better than 0.5ppm
Frequency accuracy: better than 0.5ppm (boot 5 minutes)
An interesting additional feature says this equipment can be connected to HAM RADIO DELUXE software. The user can choose any ICOM equipment, but the IC-718 is recommended.
The text also states that the version they are shipping to the USA is set up to transmit only on the Amateur bands.
I’ll let you know how it goes.
