  • Leixen VV-898SP 25W Dual Band Backpack Mobile Radio What’s better than making the Leixen VV-898 into a go-box? Buying one that’s ready to go! Introducing the Leixen VV-898SP, the mobile backpack transceiver you can take virtually anywhere you need it!
Greetings one and all!
So I'm having a rather annoying issue reading from my radio. I've tried everything, leading up to finally posting my problem here. When I go to read information from radio, I've recently been getting an 'ERROR' message. It doesn't display as a popup, or anything invasive. Instead the computer and radio think a successful 'read' just occurred, but it sneaks an error in there anyway. I feel like I'm missing something stupid simple.
So here is my setup. Radio is a Leixen VV-898SP (Backpack Version) with the standard setup with stock antenna and mic. Radio pack is fully charged when off the wall, so power isnt an issue here. I'm using two different, but similar programming cables to connect it to my Windows Xp Professional SP3 32-bit machine. (Both cables Im using are stock USB-RJ45 programming cables shipped with this radio. They have worked for me in the passed.) Ive been using CHIRP (latest build) and the VV898 User v03 software to try getting the info from this radio. I haven't attempted the Jetstream JT270 program yet, but I feel the results would be similar.
After setting the proper Com Port, and making sure the stock USB to RJ45 cable was connected, I turn on the radio, and attempt to read. The radio will say 'Waiting' on the display, and will take about 30 seconds for CHIRP to read it all. It all seems like its reading ok. In CHIRP, the error message appears in the first channel. A little strange. Picture below.
Apologies in advance! I know the pictures are hard to look at. I had to take pictures of my screen.

I attempted using the Jet settings comparable with this radio, to no avail.

I tried reading it in the Leixen 1.03 programming software (Version 200.100.3), and it will pop up with a box 'Please check all connections and communication port settings!'
I know darn well my connections are sound (drivers installed and working) and my com ports are set correctly.
What could I be doing wrong? Thank you for any input.

The little cheap Leixen radios made the headlines more than once. Brick had his hands full with posting about Leixen, and quite a few reviews can be found on the WWW. The radio is also known under other names, such as Jetstream JT270M.

When I was walking the dogs a few weeks ago Teun PA0TBS joined me and took something out of his bag. It was a Leixen VV-898, which he bought for just over 100 Euros. I was surprised that this dual-band radio was even smaller than I thought; it’s actually not much bigger than a UV-5R. I’ve spent a while with the Leixen now, so it’s time for a review.

Look & Feel
If the Leixen would be a bit bigger, it would have the looks of a professional land mobile radio. Keys work well, layout is good, and the microphone is full featured and fits nicely in anyones hand.

The menu takes a while to get used to, mainly because the manual isn’t very helpful. Yet I managed to figure it out in a matter of minutes, probably because by now I’m a proficient interpreter of cryptic ChinEnglish manuals.

The inside of the radio doesn’t reveal much. I could have disassembled the radio even further, but didn’t want to risk damaging my friend’s radio.

RX sound quality
Surprisingly good, especially with the small case and tiny speaker in mind. Yet the radio will do much better with an external speaker, especially when you intend to use the radio in a car. I couldn’t hear any LF distortion, nor excessive noise. So far so good.

TX Audio
Slightly deprived of highs as well as lows. It won’t win any HiFi award, but all stations agreed that there were no other issues which would prevent one from understanding what you’re saying. Replacing the stock electret element inside the microphone for a better one might be something to consider if you want improve the TX audio.

Transmitter quality
Because I noticed a lot of intermod (see receiver section) I suspected the oscillator of being unstable, aka suffering from phase noise. That was not the case; carrier looks reasonably clean, even with reduced frequency span.

Power output
With 10 Watts output on VHF and 8 Watts on UHF (confirmed) the Leixen VV-898 isn’t trying to compete with the bigger radios. It is more than enough power for daily use, especially when using repeaters.

Harmonic suppression
I wasn’t really impressed. On VHF the 2nd harmonic is just short of 50dBm down, the 3rd harmonic is only 43 dBm down. on UHF it’s slightly better because there’s no third harmonic to worry about.

Receiver quality
The receiver is sensitive, very sensitive. With an average sensitivity of -127dBm the Leixen is amongst the most sensitive radios around. Sensitivity isn’t everything though; the capability to separate wanted signals from unwanted signals is much more important.

That proved to be something the Leixen VV-898 can’t do at all. Even on a relatively deaf antenna, a Diamond discone, I heard mixer products and out-of-band signals all over VHF and UHF.

Gimp user manual 2.10.10 free. Tabs and docks system introduced. Allows text to be re-edited. Script-fu scripting support improved greatly.

The weirdest interference, clearly an SSB signal, came from a ham radio operator nearby who was having some fun on 10 meters. He worked barefoot, and his yagi was not even directed to my QTH. It took a while before I found the source; I obviously scanned the lower part of the 2 meter band first to find the elusive signal.

Conclusion:
The Leixen VV-898 is a fun radio, let me be clear about that. Quality-wise you get what you pay for. The transmitter section could use some extra filtering; the receiver is a Halloween nightmare when you live in an urban environment. When you live far enough away from RF pollution, you might get away with this Leixen. If not, look elsewhere.

Note: the blog of VK3XRA is worth a look if you want to see another review of this radio.
