Leixen Programming Cable for VV-808 and VV-898 II

I screwed up the link when I posted about the cable. I fixed it on the original post but am posting again. Sorry!

Leixen is selling the cable via AliExpress for $9.20. (There is a sentence on the listing that makes it seem like they would only sell the cable with a radio. That is incorrect. You may order the cable by itself.)

Leixen Programming Cable for VV-808 and VV-898

A couple of notes...

1. The programming cable is the same for the VV-808/VV-808S and VV-898.

2. Leixen is selling the cable via AliExpress for $9.20. (There is a sentence on the listing that makes it seem like they would only sell the cable with a radio. That is incorrect. You may order the cable by itself.)

Leixen VV-808S: Available Now

The VV-808SV (VHF) is here. The VV-808SU (UHF) is here. This is what the site says about the difference between the 808 and the 808S along with a warning (that I still think is directed at me):
1. Maybe many people ask me what is the difference between VV-808S and the old version VV-808. To be honest, it is just update some bugs and add some functions. It make the radio more convenience for use.
2. Please don't disassemble the radio yourself even if you are a seasoned ham, because you might broken the radio in accident. And you won't entitled for the after service since you disassemble the radio.
They updated the feature list with the following information/changes:
6. PTT ID (Voice broadcast PTT ID. NEW:Display 14 Digits)
31. Input frequency by using hand microphone (Up/Down can be set by the buttons of the side of the Microphone)
37. Power Supply: 12V/24V.

Leixen VV-808: Red 245 MHz Thailand Version

Leixen is offering a red Thailand version of the VV-808 in 245 MHz. I only see the listing for a bulk order of 30 at $95 each, so $2,860 total.

Leixen VV-808: Sale

I got an e-mail saying the VV-808 (VHF version) is on sale for $118.24 including shipping to the US. (The UHF version is still at $144.04 with shipping.) That's not the sub-100 number I think starts to make it interesting again and I don't know if this is just a temporary sale to gauge response.

Rotary Encoder

I got the rotary encoder in the mail today. Now, I need to carve out a little time to see if I can fix this thing.

Leixen VV-808: Popping Issue Fixed

Eileen sent me an unprompted follow-up e-mail on the popping issue - which, to me, is a good sign that they want to provide high quality products and fix any issues that are discovered in the field. Here is what she wrote:
"For the "popping" sound, it is a procedure problem, some radio would appear the "popping" sound often, and some may appear seldom, so people ignore the "popping". For fix the problem have to change the CPU of the radio. So it can just fixed by us. If some one want to send the radio back for fixing the problem, we will fix it for free, but he should pay the freight cost. But I think the freight fee maybe too expensive, so if some one can change the clip as attached by himself, I can send one to him. But I think it is difficult for ordinary people. As you know, disassembling the radio may break the radio, and changing the clip would be much difficult. And we won't warrant the radio again since it is disassembled."
I read that as a software/code (procedure) problem in the firmware. Since the chip has to be replaced, then it must be like most other radios with a write-once chip. She sent the picture below, too. I think replacing that chip is beyond my skill level. (I'm just hoping to fix the rotary encoder when I get it and that's just three solder points! That's complicated enough for me.)

Leixen VV-808S

I also asked Eileen about the VV-808S that is listed with the VV-808 and VV-898 on their site. She says:
"The VV-808S is a upgrade of VV-808. It updates some bugs, and plus some functions. For your VV-808, the bugs is nearly updated. So it may not have much differences to you."
More info as I get it. The VV-808S is not available via AliExpress yet.

Leixen VV-808: Popping Follow-up

I sent my video of the popping sound to Leixen and got the following response:
"We know what you mean for Popping. We did test, it really popping sometimes when the antenna connected. For the PoPPing, We can't find what is the problem for now. We will try to solve the problem. Thank you for your feedback."
They've been quite helpful (including with getting a rotary encoder), so I really hope they are able to solve this issue. I'd like to buy another VV-808 or two - one for the office and two for the cars. I'd like to standardize on one radio and this one is small enough that my wife won't balk at having it put in her car. Plus the price is pretty good even with the increase after they sold the first several.

Rotary Encoder

Thanks to Ken who pointed out that I can get a replacement rotary encoder. I suspect Eileen Lin of Leixen, who has been trying to help me, had to post it, so I could order it.

So that's what one looks like when it isn't in several pieces. :)

Leixen VV-808: More Popping

So it isn't just me and this is a UHF version. Thanks to SA0CEO for sharing the video! Also, I will add that when the radio is scanning, it is almost continuous popping on mine.

Another fancy iPhone video, but for giving you a small taste, I think it works.

Leixen VV-808: Popping

Still popping.. squelch is all the way up, tried a difference antenna, and operating from a different QTH. The popping volume is independent of the volume setting of the radio. Sorry for the iPhone video - working with what I got - but you can hear the pop at about 6 seconds. I don't see the green light come on like when SQL is broken and I am actually receiving.

A Theoretical Question

I have this friend...

Say a couple of guys were looking at taking something apart... because that is what guys do. Just to keep this on topic, let's pretend it was two hams and they were taking apart an inexpensive Chinese mobile radio.

The first guy, who bought the radio, took a few screws out and couldn't easily pull the cover off, so he hands it to the second guy and says, "Can you get this apart?"

The second guy messes with it for a second and then hands back the radio with the cover off. Ta da! Slice of pie, piece of cake!

A little while later, the first guy notices this:

Which leads to this:

And this (sorry - not a great picture, but you get the idea):

So, apparently, it is important to take off the knob first before pulling on the face plate as the plastic that holds the rotary encoder together isn't designed to take much force. Go figure. Oops.

The radio still works - you can use the controls on the microphone. The display is messed up (see image). It is unknown when that happened - during the opening of the case or during subsequent "trouble-shooting." Transmit and receive both seem fine.

The first guy feels like he setup the second guy for failure by just handing him the radio and asking for help. He doesn't think the second guy owes him anything at all.

The second guy feels extremely guilty and wants to pay for the broken radio.

So, theoretically, do you think the second guy owes the first guy anything? I'd like the internet to be the final arbiter in this as we can't keep passing cash back and forth.

Leixen VV-808: Disassembly

1. Remove the knob for the rotary encoder by pulling straight forward. Mine was very tough to remove.
2. Remove the three screws from the front face plate.
3. The face plate is connected to the main board via a ribbon cable, so gently pull the face plate forward.
4. Remove the four screws from the main part of the radio.
5. Lift the cover straight up.

At that point, all the easy stuff is done.

In my radio, the board with the display is marked:


The main board is marked:

Leixen VV-808: VV-808S

Just noticed this while looking for an English manual:

DTMF / two tone signaling / identification code, Stun / remote halo / activate full-featured voice encryption and other security safeguards your call,
12V, 24V adaptive.

And this:

VV-808S car radio upgrade notification

VV-808S is a VV-808 based on the upgrade, upgrade more powerful, microphone in hand to support the company's UP / DO function, 12V/24V adaptive, the convenience of our size car customers.

Leixen VV-808: Pop

I've got an annoying "pop" from the radio. I hear it every 10 seconds or so and then it won't happen for a minute. I bought a cheap antenna (MFJ-1721) to use with the VV-808. (I hate to spend a ton on accessories for my cheap radios. Also, that was what was in the big box.) My trouble-shooting has been limited to disconnecting the microphone (pop still occurs) and disconnecting the antenna (popping stops).

I'm back on the road again, so I don't expect to figure anything out today.
