This, as you can imagine, was a bit of a pain especially when QSYing to other frequencies. At that setting, both transmit and receive would actually be 27.555. For example, say I was on 27.55500 I would use the clarifier to adjust the frequency to show 27.55450. I had noticed that when using SSB on this radio I always had to use the clarifier to adjust the apparent frequency down by 500Hz. * Dimension: 120x90x40mm (4.7”x3.5”x1.6”).I don't know whether I am the only person to have suffered from the problem of the frequency display on the CRE8900 not matching the actual frequency, but I thought it might be useful to post this, as it offers a solution, should I not be alone. * Lease Function (can program lease time termination) * Wide/Narrow band selection (25KHz/12.5KHz) * Monitor, RX Inhibit, RXTX Inhibit and Emergency Alarm * All calls, group calls and selective calls Note: the blog of VK3XRA is worth a look if you want to see another review of this radio. When you live far enough away from RF pollution, you might get away with this Leixen. The transmitter section could use some extra filtering the receiver is a Halloween nightmare when you live in an urban environment. The Leixen VV-898 is a fun radio, let me be clear about that. 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. He worked barefoot, and his yagi was not even directed to my QTH. The weirdest interference, clearly an SSB signal, came from a ham radio operator nearby who was having some fun on 10 meters. Even on a relatively deaf antenna, a Diamond discone, I heard mixer products and out-of-band signals all over VHF and UHF. That proved to be something the Leixen VV-898 can’t do at all. Sensitivity isn’t everything though the capability to separate wanted signals from unwanted signals is much more important.
With an average sensitivity of -127dBm the Leixen is amongst the most sensitive radios around. The receiver is sensitive, very sensitive. on UHF it’s slightly better because there’s no third harmonic to worry about. On VHF the 2nd harmonic is just short of 50dBm down, the 3rd harmonic is only 43 dBm down. It is more than enough power for daily use, especially when using repeaters. 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. That was not the case carrier looks reasonably clean, even with reduced frequency span. Replacing the stock electret element inside the microphone for a better one might be something to consider if you want improve the TX audio.īecause I noticed a lot of intermod (see receiver section) I suspected the oscillator of being unstable, aka suffering from phase noise. 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. Slightly deprived of highs as well as lows. I couldn’t hear any LF distortion, nor excessive noise. Yet the radio will do much better with an external speaker, especially when you intend to use the radio in a car. Surprisingly good, especially with the small case and tiny speaker in mind. I could have disassembled the radio even further, but didn’t want to risk damaging my friend’s radio. The inside of the radio doesn’t reveal much. 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 menu takes a while to get used to, mainly because the manual isn’t very helpful.

Keys work well, layout is good, and the microphone is full featured and fits nicely in anyones hand.

If the Leixen would be a bit bigger, it would have the looks of a professional land mobile radio. I’ve spent a while with the Leixen now, so it’s time for a review. I was surprised that this dual-band radio was even smaller than I thought it’s actually not much bigger than a UV-5R. It was a Leixen VV-898, which he bought for just over 100 Euros. Brick had his hands full with posting about Leixen, and quite a few reviews can be found on the When I was walking the dogs a few weeks ago Teun PA0TBS joined me and took something out of his bag.
The little cheap Leixen radios made the headlines more than once.
