AOR AR-8000 Scanner

Before buying this scanner I read so many reviews and was convinced I would love this radio. Almost everyone only had really good things to say about it. Oh, what a scanner. Picks up so much, works great etc. Considered legendary, It's got a bit of a cult following. So when I got it and started using it, to say I was disappointed was an understatement. It turned out to be the worst receiver I have ever owned. It was so frustrating to use. The squelch was terrible, scanner keeps resetting itself to tiny kHz steps size and the mode kept resetting also. Speaker was muffled and didn't sound good at all.

Every action required a lot of work. This was a scanner that really showed its age. Not in condition, but with its long drawn out and annoying way of operating. Worst Auto mode ever. Battery life wasn't great either. AA batteries [it takes 4 AA] didn't last long. Even my rechargeable batteries which are 2500mAh didn't last very long. I ended up buying a mains adapter from eBay [pictured]. I got lucky and managed to find a cheap original AOR adapter. But still, it didn't really make my experience using the scanner any better. It was just too frustrating to use.

I have to say, this is the only AOR receiver I have ever had, and going on my experience with the AR8000, it will be my last. Specs were good on paper, and reviews were great, but using this scanner in real life was a pain. Comparing the AOR8000 to my Quansheng K6 [upgraded with Egzumer software] was a real eye opener. Like night and day. The Quansheng was 10 times better. So much easier and hassle free to use. Functions and settings are easy to perform, screen is excellent, squelch is good overall, and the speaker is much clearer.

Receive Strength

This surprised me the most. After reading all the reviews about how good the AOR8000's receive strength was, I expected it to pick up signals that my upgraded Quansheng had no chance of receiving. This was not the case at all. The AOR and Quansheng K6 were nose to nose at picking up signals. The only difference was that the signals on the Quansheng were much clearer and had a better quality about them overall. Now, I know that the AOR8000 is old tech by today's standards but still, I never thought for a second that a cheap [but great] radio from China would basically outperform one of the legends of the scanner industry. I expected the complete opposite.

I think it just shows how far radio technology has come, and how cheap a good performing radio can be once you strip away all the marketing hype and over the top profit margins. I sold my AOR AR-8000 handheld for a cheap price to a guy on Gumtree who already had one but needed another one for parts. He was very happy with it. But I think he had owned his AR8000 for a long time and was so used to using it that he'd rather fix his old one than buy something else. Good on him. But for me, I couldn't get used to it and I would never buy another one. 

Baofeng 1701 Inverted Screen + More

The Baofeng 1701 screen can be changed to almost any colour combination that you can think of. But for the colour changes to save permanently, it needs to be programmed with the CPS software and cable. Without that, the changes made to the screen will look like they have been saved while the radio is still on. But turn the radio off, then back on, and you will see the screen has gone back to its default white setting. If the user has the CPS software and cable this is not an issue as all display changes are done through the software and permanently saved.

I didn't buy the cable with my radio, so none of the changes I make with the screen colours can be permanently saved. But there is still one way to change the screen colour that will be permanently saved, even without the cable and software. And that is inverting the screen colours. This is easy to do from the radios menu. And I think I prefer it to the full on white.

To do this follow the instructions below. Please note. My Baofeng 1701 has OpenGD77 installed. So the menus might be a bit different if your model does not have OpenGD77 installed.

How to make the screen inverted [with openGD77 installed]

Click on the highest green button on the left to go to the menu. From there select "options". Click on "display options". Scroll down until you see "Screen: Normal". Use the scroller wheel knob at the top of the radio and select "Inverted". Press the green button on the left [above the P1 button] to save changes. And that's it, the screen is now inverted to white writing with a black background rather than the other way round.

DMR: Leveling Out The Audio

In another post about the 1701 I talked about how one of the things that was quite annoying about this radio, and maybe DMR in general, I'm not sure, was the fact that the audio levels were totally out of whack. Like, when listening, [RX / receiving] one side of the conversation would be at a nice volume, while the other side of the conversation would come through so loud and almost blow my ears and the speaker up. After a bit of research it turns out there is an option in OpenGD77 that somewhat addresses this issue. 

It's called DMR Rx AGC. While the developers of OpenGD77 do state that its not perfect, turning this setting on can help level out the audio levels so they are more balanced on each side. I am testing this out right now but first impressions are that it is making a difference. This is great because the difference in audio volume levels from either side of a received signal was ridiculous and required constant adjustment of the volume knob to keep the volumes at a reasonable level from both sides.

If you want to turn this feature on please follow these instructions. Press the top green button [above the P1 button] to go to the main menu. Click "options". Then "sound options". Find DMR Rx AGC and use the top scroller wheel knob to select one of the dB options. Mine is set to 0dB and that seems to be working well, so I would recommend you use that to begin with.

You can always test / change it to something else in the future. Once 0dB is selected press the top left green button to save the changes. And that's it. Hopefully you should hear a change, making the audio volumes more balanced from each side.

Baofeng UV-28 Plus Tri-Band First Look

Quick first look at a new analogue radio from Baofeng. The Tri-band Baofeng UV-28 Plus Transceiver, with GPS, Bluetooth and App Programable radio is a really nice, well equipped radio for the price. The App is basic but can be used to program the radio not only with the Windows operating system, but also with Android and Apple iOS. This opens up the programming abilities for a lot of people and should make the radio easier to live with. The frequency range is as follows: 76 - 108MHz, 136-174MHz, 220-260MHz and 400-520MHz. It's a 10Watt radio and Transmit power seems good in real-time.

 

Good screen colours, nice audio, well-lit display and keypad. Average build quality. Airband reception seems a bit poor, with some scratchy / choppy signals, but could be decent enough with the right antenna. PTT button is a bit different to what we see on a lot of other radios in that it's quite flexible when pressed or messed with on every angle. Most PTT's are solid and don't move other than in and out when pressed. This one is more flexible / wobbly. But secure and intended to be that way [wobbly] by design. Some might like it, and some might not. Anyway, for a full in-depth review of the Baofeng UV-28 Plus, please watch the YouTube review video above. It's a long video but worth a watch if you're considering buying this radio.

Castle Vale CB Radio In The Mid 1990's

I'll always remember when I heard CB radio for the first time in the mid to late 1990's. And it wasn't a nice conversation. It was an argument between two guys. One of them was definitely from Castle Vale, and I'm not sure but I think he was in a tower block which was called Concord Tower [now long demolished]. I can't remember his name, but he went by the callsign / handle of either silver rod, silver star, silver bolt, or silver something. If I could take a guess I would go with silver rod. These two guys were arguing over who had better equipment in their homes, and who owned better stuff. Comparing stereo separates, clothes, scanner radios, all types of stuff. I couldn't believe how materialistic that "silver rod" guy was.

Over the weeks / months of listening it became clear that this silver rod guy was a complete idiot, arguing with anyone and everyone about having better stuff than everyone else, like it was a competition. It was all he ever talked and argued about. Bragging about his CB setup, his Bose separates and speaker systems, His Armani Jeans, how he has loads of money and only uses things he buys a few times and then throws them away etc. He literally only went on the CB frequencies to argue with people about how much money he had and start trouble.

Not sure what happened to him. But I think trouble may have found him. I remember a few times him having arguments with people and arranging to meet up and fight it out. Maybe someone took him up on his offer. This isn't out of the realms of possibility either, it does happen. I've heard people on the CB's in the UK arrange to meet and duke it out a fair few times. And sometimes it has happened. There was something similar recently, where someone was shouting his mouth off. 

He is well known on the CB radio circuit in the Birmingham area. I do know his name but I won't say it. Anyway, he started giving it the big one and said something quite bad about someone's family member. And because some of the CB community in the Birmingham area is quite tightly knit [they know each other in real life and meet in person regularly, go to each others houses etc], people knew where this loud mouth guy lived. So the person he was arguing with went round to his house and punched him in the face.

Did he deserve it? Possibly. However, he is a total pisshead and sounds harmless really. All talk. A fragile alcoholic that most people would be scared to hit in case serious damage was caused. So most people wouldn't have bothered. It wasn't worth it. But sometimes you get one that's young and / or stupid enough to take it to that level and not think about the consequences. Thankfully the guy who got punched was OK afterwards. He tried to save face by coming straight back on the CB chatting away like he was unfazed by it all. But I think that encounter shook him up and taught him to have a bit more respect. 

Anyway, I wonder if something similar happened to silver rod... I listened to him for a while back in the mid to late 90's, then I was busy with other things and never listened to CB radio for quite some time after that. You have to remember, scanners were much more interesting in those days with the Police, Ambulances, the Police helicopter, cordless phones etc. CB radio seemed quite boring in comparison. When I returned to CB radio some years later he was nowhere to be heard. 

Although I have to admit, I never stuck around for long as I was always so busy in those days. Always outdoors living life. Does anyone remember "silver rod" [I think] from Castle Vale and what happened to him. I would love to hear if he ever grew up, became a better person and looked back at how much of an idiot he was. Hopefully he did. I wonder if he's still out there, still listening in after all these years...

Listening To SDR Frequencies Online Free

If you don't have an SDR dongle, a normal scanner, or a portable SDR receiver like the Malahit DSP2 , there are still ways to listen to SDR radio. There are some websites that list lots of SDR / Scanner frequencies from all over the world that can be listened to online for free. I was quite surprised when I found a few to be honest. I never thought they existed. But technology just keeps on rolling forward. All you really need is an Internet connection to tune in.

Image: One of the channels I have been listening to: g0xbuwebsdr.ddns.net

I've been listening to all types of stuff. American CBs / truckers, people talking in little towns in Utah, 2 meters in the UK, CBs from all over the UK, airband and much much more. Basically, anything you could listen to on SDR radio or a normal scanner multiplied by 100 due to your signal range not being limited to the capabilities of your own radio equipment.

So, many countries can be heard. I only understand English, so I just stick to the English speaking countries. But there are so many that are foreign, like Russia, South America, France, Italy, Netherlands, Finland etc. Something for everyone really. 

Of course, the big difference here is that with scanners / SDR dongles etc, no Internet is needed to pick up signals. But obviously with only listening online it is absolutely needed. Still good though, as almost everyone has the Internet these days. But if the Internet goes down your hours of listening to SDR online are over... For a while.

Anyway, my favourite websites for listening to SDR so far are:

How To Scan Saved Channels Egzumer

So this is presuming you have already saved some channels to the memory that can be scanned, and that Egzumer is already installed. First off, turn on the radio. You should now be in the VFO dual frequency screen, in frequency scan mode. There will be an "F" to the left of the frequency. Press and hold down the number 3 on the keypad to toggle between frequency scan mode and memory scan mode. On the screen, "F" is for frequency scan and "M" is for memory scan. Make sure M is on the screen so that memory mode is selected. Please see the picture enlarged if you are unsure.

Image: Picture shows memory mode "M" selected, and the two "I" symbols which represent scan lists.

Make sure that there is at least one "I" looking symbol is to the right of the frequency in the top corner. These "I" symbols represent scan lists. There is a total of two of these. If both scan lists are selected you will see 3 "I" like symbols next to each other in the top right hand corner. One on its own, and two close together. This means both scan lists are selected [On] and will be scanned once a scan is started. To toggle between scan lists, turn one or both on or off, press and hold the number 5 on the keypad for a second when in memory mode. You will see the I's in the corner disappear and reappear when pressing and holding number 5. For the first time, make sure that all three I's are present in the corner.

Now to scan the memory channels just press and hold the scan button on the keypad. Once it starts scanning release the scan button. And that's it. You are now scanning the saved channels like a normal scanner would. You can then use the up and down arrows to to scan up and down, or continue scanning when it stops on a channel. If it won't scan further than one channel up / down when using the arrows, just press and hold down the scan button again to continue scanning through the channels.

In Summary:

• On the main VFO dual frequency screen in frequency mode - Press and hold down number 3 for one second to activate memory mode.

• Make sure scan lists are selected ["I" symbols in the right corner]. If not, press and hold down number 5 for one second once or twice to activate one or both scan lists.

• Press and hold down the scan button for one second to start scanning your saved channels.

These instructions are the same on all radios that have Egzumer installed. So this will work with the UV 5R Plus, UV K5 8 and K6.

Rare PINK Quansheng

Came across this on the Quansheng subreddit and thought it was quite cool. Never seen one before. A rare bright pink Quansheng K5 / K6. The person who bought it said they got it from alafone.com, and it goes under the colour "red" on that site. But it is pink. It's the same as any other Quansheng UV K5 8 other than being pink. I did do a quick search on Aliexpress and Amazon to see if it was available and it was not. I did find a nice blue one for sale that I've never seen before though. I had a quick look at the website where the person bought it from and on there it is called "rose red" in terms of the colour name. There's also some camouflage / army green / desert style Quansheng's also.
