Xiegu X108G Outdoor Version

Continued Review: October 14, 2015

Having played with the radio mostly doing some CW operations and some shortwave listening I have stumbled across a few little issues that I am hoping can alos be fixed by Xiegu by way of firmware issue.

I have to say once again that this little radio does pack quite a punch for what is in the box, and at the same time this radios performance is guaranteed inside the amateur radio bands, anything else like expecting a hard headed shortwave radio or am broadcast band radio for DXing might be just a bit naive.

Again I have operated this unit on cw and have still to test it on SSB. But in my cw tests I can tell you that the cw tone tested against other radios seems to be spot on. When up against the FT-857 the blue light flashes right along on the same frequency. The 500hz filter also works extremely well and takes all that noise out and allows working the intended station easy. I run the radio with the ATT off and signals are clearly heard without a problem on my windom. I used straight key for my operations but there appears to be an issue with the built in keyer, it wants to add extra characters so until this is fixed stay with a straight key.

So what have I found that needs to be addressed on this radio, let me start:

I was attempting to check into a voice net on 40 meters one evening as they were looking for checkins on phone or cw. So I figured I would test the split function out and set one VFO to cw and the other to SSB, well I was surprised to find that the radio will not transmit cross mode, I would have to have both VFO’s in the same mode to do anything which did not work obviously.

The second issue that brought me to this split mode was the fact that no CWR (CW Reverse) is present that will allow me to listen to the required SSB while in cw mode to check into the same net.

This has been addressed with Xiegu to see if there is a firmware fix for the issues stated, including the Iambic keyer problem. As the radio is now it would make a good SSB rig, but performance as a dedicated cw rig and not being able to check in using CWR kind of takes away the joy of portable use and using the radio as a go-kit emcomm rig. The 20 watts of power and its size is nice when you need that extra bit of punch.

The multikey microphone as well as the two programmable keys makes the mike a handy addition to this radio. HRD can be used and the IC7000 is the settings that are used in HRD to use the radio. We are still working on pin outs for the ACC jack to figure out if full PTT and audio in and audio out are present for digital operations and HRD.

Voltage Test: I did a voltage test to see what the minimum lowest power was to allow this rig to operate, this was asked of me by another portable radio operator. So I found 11 volts is the absolute minimum that the X108G will operate, once 11 volts is reached the radio will then start to motorboat and funny things happen to the radio, many of my battery packs I use for portable operations and teh other radios I use will cut off at 10.6 volts.

The other test that I want to do is to test the radio against an SDR radio like my KX3 or even by SDR dongle to see if any transmit spurs exist outside of the ham bands while in cw. This radio has attained FCC Certification so I know it has already gone through some hoops and hurdles.

So while I await a response from Xiegu I will continue to enjoy this little radio that has been designed as a minimalist radio with no extra bells and whistles attached to it.

The price is certainly falling for this rig, but quite a few people have expressed disappointment. I cannot comment on these reports. Some are disappointed saying it is, “cheaply made”.

This is a trend of our age: I have noticed that M&S underpants are now thinner and not as good. My wife recently bought a coat (not M&S) and this was thinner than the one it replaced.  No, making goods to fit a price seems to be the way things are today, rather than built to last. This says lots about our “consumer society”. Things are not made to last any more: they are designed to wear out or fail so we buy new items.

This is a state of affairs that ultimately cannot last.

The next world radio conference (WRC-2015) is drawing close to opening. Worldwide, radio amateurs are hoping for a contiguous 5MHz allocation, rather than the channelised allocations common in many countries. A 60m band would be really useful as the sunspot numbers decline and the higher HF bands become far less useful for DX. Whether this contiguous allocation will happen remains to be seen. Most of the lobbying has been done, so I guess we now have to wait and hope.

My new copy of RadCom is due towards the end of next week. I wonder, if as in PW, there will be a “tight lipped” policy as appears to be the case for all advertising in PW a few weeks ago? You can almost hear ICOM saying, “do NOT sell the IC7300, as this is for NEXT year, if at all”.

Certainly the UK selling price of the Yaesu FT991 has, as predicted, dropped some way. This will go lower still in the months ahead. If the IC7300 has had to be delayed (software issue maybe, or are they afraid the lack of 2m/70cm will be a problem, or is there a major design issue, or are they worried about the selling price versus the Yaesu FT991?) this would be a great shame.

I was expecting to see this in the UK by Christmas and selling for less than the FT991. I now have my doubts. The next RadCom may give us some clues.

X108G Review October 2015

By: Fred Lesnick VE3FAL

http://www.cqxiegu.com

Note: All firmware updates are done at your own risk and caution should be used when installing or updating any firmware into this radio. The removal of any covers or mods will void your warranty. Never hit the RST button while in the engineering menu. All settings should be written down and stored in a safe place in the event that RST is hit or if a firmware update makes any changes as all radios are aligned individually. To find these setting do the following then take a picture or write them down:

I placed an order for the Xiegu X108G and it was shipped from China via D.H.L. on Sept 25 and arrived here on Sept 29 2015 at 12:30 PM. The unit was well packaged and no damage to the box at all after the trip from China. Inside the box was the X108G, Xiegu sticker, power cable (much longer then first models, but still no in-line fuse), microphone and microphone cable, as well as USB cable for firmware updates. Manual for radio was in the box and a warranty card with serial number of radio attached. The radio is equipped with front and back handles.

Unboxing the unit after its arrival:

Powering The Radio Up

An inline fuse should be installed on either one or both of the power cables before the radio is powered up to avoid any damage to the radio. I finally got the chance to power the radio up and see how this unit plays after all the updates and fixes that Xiegu made to make this radio a seller. First thing I did was to put my call-sign into the radio, this is undocumented but was found by a fellow X108G owner while playing with the radio.

This is how it is done:

Press F3 on powering up. Use the VFO to select letters/numbers then to move onto the next letter press INS button for each letter or number, when finished hit save. The radio will power back up. Switch it off and on again and you will see your call sign where the word Xiegu used to be.

Powering the radio up (continued)

After going through the supplied Operating Manual and getting familiar with what each button does (many changes to these buttons since versions 1 and 2) I was ready to hook my windom antenna to the SO239 connector and listen on 20 meters SSB for a bit. Tuning across the band with the 2.3k filter on signals were clear and clean, I was in AGC-S and pre-amp was in off position. Signals on 14.300 were an S5 with the pre-amp off and came up to a solid S8-9 with the PRE on, no distortion or overmod was heard or encountered nor was any splatter from adjacent signals heard. A move to 40 meters and LSB I was able to pick up a station on 7.188, and just like USB signals were right on where they should be, I was listening on my VX1700 with windom as well and noted the similarities in signal and quality. Once I was happy there I went to 20 meters and tuned to CW and went to 14.020 and monitored a station in the UK working an N3 station stateside, both signals were S5 and I had .5k filter on and no stations nearby were heard breaking through. A quick tune by the PSK frequency on 14.070 yielded a bunch of PSK signals. Next will be to hook up a key and attempt some contacts using a straight key and testing the waters that way. I will also hook the microphone up and try make a few SSB contact and get reports on both USB and LSB to compare. Videos of the radio in use and contact’s will be recorded so others can see and hear how well this unit works.

So what are some of the features this radio offers? First off is the display on the outdoor version, this display is bigger and brighter and designed for use outside where it is brighter, of course a video and pictures to show this will follow. Next is low current operation, with my power supply set at 13.1v on receive my meter shows 600ma of current draw, the stated current draw on transmit at 20 watts is rated at 7.5A, but again I will test this later. 2.3k and .5k filters for SSB and CW choices. The radio offers SSB,CW and AM modes and can be tuned from .5-30mHz and includes all shortwave bands in between the filtered amateur bands. Multi-function microphone. Variable power output from .5 to 20 watts. Adjustable microphone compression, Dual VFO’s, Split feature, accessory port for digital modes as well as jack for morse code key and external speaker. Many other options to list but will talk about those in a later review.

So this is a start and looking forward to playing with this radio and putting it to the test. I should add there is a 1 Year Warranty on this unit from date of purchase.

Communication‘s with Xiegu as well are fast. Xiegu also monitors the X108G Yahoo Group which can be found here if you are looking for more information as well about this radio and what other radio owners think of it, the group can be found here:

https://groups.yahoo.com/neo/groups/X108-Transceiver/info

I look forward to taking this radio out portable and testing it and bringing more information out there for potential radio buyers.

It Can Still Be Done! Kit Building is Alive and Well
By Kevin O’Hern Carey WB2QMY

Kit building is as old as amateur radio and as popular as ever. The attraction to kit building comes from the learning experience of building an electronic project, the pride of knowing how components work and the money saved by doing it yourself. A longtime kit builder himself, Kevin shows us that kits for all kinds of radio projects are readily available today, but that it’s also a fun experience to do with your children or grandchildren.

Digitally Speaking: The Original Digital Conversation
By Cory GB Sickles WA3UVV

This month our digital guru goes old school as he examines the original digital conversation: Morse code. The attraction of CW is multilevel: it’s a mode available to all license classes, an efficient use of bandwidth, and a natural for low power DIY ham stations. Furthermore, savvy CW operators can put together a small, capable station at a fraction of the cost of voice mode stations. Despite the fact that the Morse requirement for amateur licenses was dropped in early 2007, CW operating is a popular as ever.

TSM Reviews: Manhattan DJ-1997 FTA Satellite Receiver
By Ken Reitz KS4ZR

The new Manhattan DJ-1997 receiver is smaller and less expensive than its predecessor and yet more capable. It goes a long way toward blurring the lines between traditional cable and satellite TV services and the new direction consumers are inevitably migrating toward: Over the Top TV. We’ve seen similar activity with services offered by new TV sets: direct access through apps to Netflix, Hulu, Pandora and a host of other non-cable/satellite video and audio services, including direct access to Web content. This is disruptive technology in the best sense of the word.

The Norden Broadcasts: America’s Ace in the Hole
By J. Wandres

While British forces in WWII had mounted successful radio-based propaganda campaigns, the US had no such program until 1942 when the US Office of Naval Intelligence put together an unlikely trio, which included a doctor, a lawyer and a Hungarian émigré. They created a fictitious character named Commander Norden and broadcast what they said was the truth in German aimed at German warships. But, how successful was the program?
