Hong Litong HL-UV8R

So the question was asked if the $58 Hong Litong HL-UV8R was a tri-bander. Hans and others said that it
was a mono-bander that was available in various flavors. Hans even offered this mini-review:

"These are mono-band radios. Unless something improved over the last year or so,
these are NOT recommended.
My experience with this radio:
- TX audio muffled
- LCD hard to read
- Battery life disappointing (rated 1500mAh, but actually 1200mAh)
- Charging takes ages
- Parts started to fall off within a month or so
- VCO/VXO locking problems"
There is, of course, a Yahoo Group for the UV8R. (Not to be confused with the UV-8R.) No one on the UV8R group seems to know much about the radio.




And now, we have Donald who says:
"got mine yesterday. 
hong litong hl-uv8r:
2 meter,220 and 440
just a little bit bigger than uv3r
easy to program
5 watts 440
6 watts 220
loud rec audio
keypad lights up
100 channels
only has hi and low power out
mine came with bad charger.
im going to exchange it for another.
$44 cant beat it, if i can get one that works right."
That's surprising and based on all the other comments, it would mean something has changed.

Puxing PX-888K

Steve and JLWilkers mentioned the Puxing PX-888K in the comments (here, here) a couple of weeks ago, but Hans (PD0AC) is about to get his hands on one. Quoting Hans, there are a few features that make this note worthy:
  • 5 tone selective call (ZVEI,EIA,CCIR). These tones are often used in professional environments, which makes this radio compatible with commonly used professional hand-helds.
  • Scrambler, 8 groups. Although banned by law for for use by Ham radio operators, this can be a lot of fun and adds a basic level of privacy. The word ‘groups’ is presumably another word for the various frequencies which are commonly used used in voice inversion systems.
The 409Shop has them for $80. Don't forget: you may want to pick up the PX-888K in bulk to get a free jacket or polo shirt!

Baojie BJ-UV55/HYS TC-UV55

Given the luke-warm reception of the Wouxun KG-UV920R, everyone is looking at some alternatives. Following is a essentially a guest post by Nate as he reviews the HYS TC-UV55 (Baojie BJ-UV55) by watching a video review by Andre Silva of Brazil. These mobile radios were first mentioned in his earlier Mega List guest post. I've done some editing, so assume any mistakes are mine. (Already updated as I've made plenty of mistakes! Hopefully, they are fixed now.)

Many thanks to Nate for the in-depth review!

Here is basically a "second hand" review as the video is not in English and Nate could not understand what he was saying. Basically, he watched the display and compared the specs listed in the catalog page.

This video consists of two parts. It is probably not a complete overview of all the features and menus of the HYS TC-UV55 - some key features weren't even showed. (He was using the pause buttons to check out all the settings, etc). The unit sells for about 2/3 of what they want for the KG-UV920 on AliExpress. Actually, the video is about the HYS TC-UV55 (which is essentially the same radio as the Baojie BJ-UV55 based on the specs and this video).

Part 1 Highlights

- Unique way to enter frequencies, the MHz button actually allow you to change digit by digit, most radios will just allow 1 MHz steps, and then you have to scroll up or down up to 500KHz .
- 36 Menu items (00-35).
- Offset steps - 10 KHz. Same digit by digit entry Offset Frequency (can be set between 0 and 69.9875 MHz in Frequency Mode).
- To switch between VFO and Memory Channel mode, he turned off the radio, held the MENU button while turning the radio on again. This seems odd, but I don't understand what he says. There could be a more conventional way to switch between VFO and Memory Channel. Here is a video from Thailand showing the Baojie BJ-UV88 HT radio and the guy demoing the radio did the same on the HT.
- The display can do VV VU - U+V,U+U,V+V,V+U dual band working mode can be selected arbitrarily Dual Frequency standby in any band.
- The button to the left of the MENU button, is the SCAN button.
- BDR function? TX-AB function?



Part 2 Highlights

- The display backlight can be turned off.
- Separate Tone Squelch or Digital Code Squelch can be set for TX and RX.
- The video gets cut at the end, but no Part 3...




Misc Notes
- A lot of similarities to the Baofeng UV-5R (The menu system is actually the same as the Baojie BJ-UV88 handy talkie).
-The Menu button is used to enter the item/save the change.
-The display shows a used memory channel the same way the Baofeng UV-5R does: CH-001 - used channel 1, 002 - empty memory channel 2.
-Like with the Baofeng UV-5R, programing a channel for the second time, the second frequency will become the TX frequency, the first will be the RX frequency, the display will show +-
