The Buzz
The recent entry of the Anytone 8R series has raised some eyebrows lately.  Here, we are going to take a look at the TERMN-8R (aka terminator). First, this is definitely not a rebranding of an old design, but a fresh set of features not usually found in one model.

Features such as a Bi-Directional Cross Band Repeat function, Pre-programmed Weather Channels with Alert Tone, and 2TONE and 5TONE squelch and Paging for the EMS and Fire services, and the Part 90, 95A, 95J certifications for Commercial, GMRS and MURS in the US.
 
What’s in the BOX
A nicely written and illustrated 104 page English manual, belt clip, lanyard, Earpiece/Microphone, 7.25 inch (18cm) flexible antenna and hefty 2200mAh 7.4V battery with charger.

I noticed the side of the 2200mAh had a small charging jack. When I checked the AnytoneTech accessories page, I found that a 12V mobile charger is available for on the road charging.

First Impression
After inserting the battery, you immediately notice the overall weight and feel of the radio. It has a solid feel and fits my large hand nicely.

The top of the radio has the traditional Volume/PowerOn switch and Channel Selector. The left side has the PTT switch and well as two programmable function switches. The right has a 2 pin ‘K2′ Kenwood, Anytone, Wouxun, Baofeng style connector, meaning most available accessories will be totally compatible.

My prior Anytones have somewhat of a concave keypad. I found the button access much easier. The keypad numbers and definitions both light up making manual programming a bit easier.

Transmitter
The TERMN-8R transmitter has 3 power levels. For Normal operation, the power levels can be changed from the keypad. In the GMRS and MURS mode, the power levels are fixed. My Over the Air contacts have received excellent quality and level reports.
Power Levels clock in as follows:
VHF – 5.6W,  2.4W,  1.2W
UHF – 4.5W, 2.25W, 1.25W
GMRS – 4.15W
MURS – 1.95W

Dual Receivers
The TERMN-8R has Dual Receivers that function over six bands: VHF, UHF, Aviation Band (108-136MHz), Shortwave (AM 2.3 – 30MHz), AM Broadcast (520-1710kHz) and FM Broadcast (64-108MHz).  Both the FM Broadcast Band and expanded Aviation Band include 100 memory channels each and can be used with Fast Scan (see below)

Dual Receivers allow for receiving two signals simultaneously, rather than just sampling for activity. This is important if the sub-channel is set for Weather Alerts (1050Hz) or EMS / EmComm Services Alerts or Paging. It also provides for bi-directional Cross Band repeating.

To eliminate side channel interference, the radio’s receiver reverts to true Narrow band when selected.

GMRS and MURS operation (FCC part 95A / 95J certified)
This TERMN-8R can be switched to operate on any of three modes. GMRS, MURS or Commercial/Normal. To eliminate the possibility of being on the wrong band, a Key Press at PowerOn selects either GMRS or MURS mode. The channel frequencies are hard coded in the firmware as well as their power levels, but allow for CTCSS/DCS tones can be added/changed via the keypad.

Commercial Application (FCC Part 90 certified)
For Commercial, Fire, EMS and EmComm use, the TERMN-8R is fully certificated with 2.5kHz steps, and software which prevents Field Programming.

Cross-Band Repeater
This function allows retransmitting a VHF signal to UHF (or UHF to VHF).  To test, I set the main channel to a local VHF repeater, and the sub-channel to a UHF simplex channel, then activated the Repeat function.  Audio reports both to and from the repeater were excellent.

In this mode, both receivers are active simultaneously. The first active receive signal takes repeat priority. When that signal drops, both receivers return to active standby.

Aviation Band
I had a chance to play with the Air Band receiver that covers the entire 108 to 136MHz. Up to 100 channels can be stored and either individually selected or scanned. I entered 10 of the most used frequencies in the area, then activated the scan mode. When a signal is found, the receiver paused for 5 seconds, then returned to the scan mode. The scanning process can easily be stopped by pressing one key.

Another nice feature is Fast Scan. This increases the radios scanning rate to 10 channels per second. Three time faster than my Baofengs. Especially nice when scanning stored Air Band frequencies.

Even if your not close to an airport, keep in mind that an aircraft running 10W and flying at 20,000 ft has a range of approximately 170 miles.

Shortwave Bands (AM)
For those enjoying the Shortwave bands, there is AM coverage from 2.3 to 30MHz.  You can enter a frequency directly, then enter the scan mode if desired.  Even with the supplied antenna, I was quite pleased with what was received.  Attaching the radio to a full size outside antenna connects the SWL to the rest of the world.

NOAA Weather Alert
The seven US NOAA weather alert frequencies are preprogrammed into the radio. There are 3 options to choose from. ON, OFF and ALERT. When WX Alert is chosen, the NOAA weather channel remains silent in the background until the 1050Hz emergency tone signal is received. This is especially useful in areas where severe weather conditions are prominent.

Dual PTT Capability / Programmable Function Keys
There are two PF keys below the PTT switch. Either can be programmed to function as a sub-channel (lower display) PTT button, while the PTT switch activates the upper channel.

The PF keys can also be used to select your choice of:
– Battery Voltage display
– Frequency display
– Tone Calling (DTMF/5TONE/2TONE/MSK)
– FHSS (Frequency Hopping)
– Tone Pulse (1750, 1450, 1000 or 2100Hz)
– Alarm Button
– Dual PTT
– MONI (Squelch off)

Channel Banks
The radio supports 200 channels and 10 memory banks. Group 0 contains all channels entered into the transceiver. Banks 1 > 9 can be assigned up to 32 channels each.

I found a nice added feature that isn’t on my 3318UV-A. If I want to remove a channel from a particular bank, I can dial in the channel, press two keys, turn the knob and it’s gone. Eliminates the need to me to use the computer to delete the bad ones.

2-TONE Sequential Paging
This is extremely useful for the EMS user. I personally have used 2-tone pagers in the past (Motorola and Plectron). It’s nice to know that I can now monitor local EMS channels with one radio. The advantage of the TERMN-8R’s dual receiver is the pager tone will come through, even if the other receiver is active.

Detailed instructions on how to set up the 2-tone and 5-tone paging system can be found here.

Software
The OEM software is relatively easy to follow, and with a little practice, easy to navigate. Some areas may be a bit tricky, and I’ll try to address those area in the Miklor FAQ section.  CHIRP developers are aware of the new Anytone 8R series, but it takes time to reverse engineer the software.

As always, it is recommended to get a quality programming cable so you spend more time talking on the radio and less time loading special drivers to your PC. I personally use an FTDI cable that is Plug ‘n Play with no driver issues.

Upgradeable Firmware
The TERMN-8R has Upgradeable Firmware. If features are added in the future, your radio is not becoming obsolete. The firmware can be updated by an authorized dealer so you will always be able to  have the latest version available to you.

IMHO
I think the developers of the Anytone TERMN-8R outdid themselves on this one. The inclusion of the:
– Certified GMRS, MURS and Commercial in one radio
– Cross Band Repeater
– Two internal receivers
– Upgradeable Firmware
– 6 Band capability
– 200 channels/10 Banks
– Dual PTT
– 2TONE / 5TONE / MSK Messaging
– Stun / Kill capability
makes this one of the most versatile radios on the market.

The David Sarnoff Amateur Radio Club down in Princeton, NJ has been distributing the following announcement. They're a great bunch of guys who always put together a good QRP Field Day effort every year - so I am going to post this for them:

Pi Day Special event station – N2RE Princeton, New Jersey

Most people know John K3NXU well as the busy bee who maintains Miklor.com. Starting today, John will be an author here too.

We have a long history of exchanging information behind the scenes, but in an informal way. No surprise here; our websites have a lot in common. We started to exchange more and more e-mails lately, talked to each other on the phone and concluded that a more official cooperation would be the next logical step.

So, there we are: Miklor.com and hamgear.wordpress.com are ‘tying the knot’. We hope (and expect) that this will benefit our readers. John’s first article, his take on the Anytone TERMN-8R, will be published later today.

The 432MHz UKAC contest is usually a pretty dismal experience for me, low elevation, local noise and a mediocre antenna makes for a difficult evening. Last weekends VHF/UHF contest and some tests with fellow club member Stewart​ (M0SDM) on Sunday evening convinced me to try operating portable this week.

I have a small Moonraker 7-element ZL-Special on the main antenna mast, purchased originally for monitoring satellites and was pressed into service for SSB when I got licensed. It has never wowed me performance wise and I have been intending to replace it for quite a while but since I only use it one day a month it hasn't been a priority. So the mast came down last night and I removed it so I can take it out with me to operate portable from some higher ground tonight.

Using the 2m delta beam in June 2014

Last year I had a go at operating portable from the car and posted a write-up. It is my intention to repeat this exercise but with the 70cm antenna on top of my 'painters pole' mast. I have serviced the antenna and fitted a new short run of quality coax and spent a far amount of time with the AW07A analyser adjusting the antenna's tuning capacitor and have got the VSWR right down to 1.1:1 on 432.200MHz so things should be optimal.

I am looking forward to this evening, hoping it pays some dividends.

As I mentioned the 24 hour March 144/432MHz VHF Championship contest took place last weekend. I took part to give away some points just grabbing a few short sessions with the radio. I concentrated on the 2m band due to my issues on 70cm.

In my AW07A analyser review I mentioned some issues with my 2m LFA YAGI, thankfully these have been resolved. The use of some wire wool to remove some corrosion and a hacksaw to take 10mm from the long elements of the loop allowed the end elements to 'trombone' in sufficiently to get the antenna resonant and the VSWR is down to 1.2:1 on 144.300Mhz.

I only made 18 contacts, but was happy with the distances achieved with 30W, getting a lot further south than I normally do, given I am 18m ASL. There was also some local wideband noise (I captured a screenshot on the SDR) and the conditions gave some interesting fading.

Noise across the band

   

The ANILE-8R was not the first Anytone Tech model I unpacked, but it will be the first to be reviewed thanks to its simplicity.

Baofeng vs Anytone
In terms of design this radio resembles the Baofeng BF-666S/BF-777S/BF-888S series: 16 channels, no thrills no frills, no display – just on/off/volume, a flashlight and a 16-channel selector. Both radios tell you which channel is active by using a speech processor. Based on this the two radios could be regarded as competitors.

I kept my Baofeng BF-666S in spite of its generous amount of flaws: the receiver can be trashed by about any out-of-band signal or mixer product, the oscillator isn’t stable (phase noise, which causes reciprocal mixing), and RX audio sounds raw, unfinished even. TX audio however is fine, battery life is great, and the price (below $20) is hard to beat.

The consequence of Baofeng’s cheap design is that I only can use the radio when I’m far enough away from any RF pollution. As you can imagine I was very curious if the ANILE-8R would outperform the Baofeng or not.

In the box
The radio, antenna, 7.4 Volts 1300 mAh battery, charger, power adapter, headset, small strap, manual.

Build quality
These radios are ideal for outdoor activities, because there’s not much you can break. The Baofeng already did well, but the Anytone feels much sturdier. It’s well built.

Side keys
There are three side keys and you can program them yourself. At default the upper key will switch on the flashlight, the middle one will tell you the remaining battery voltage, and the last one will bypass the squelch (monitor).

Programming options
Scanning, priority channel selection, CTCSS, DCS, and DTMF calling methods (individual or group calls).

Phase noise
The first thing I looked at was phase noise. During instruction evenings I use the Baofeng as the prime example of poor design; all I could hope for was that Anytone did a better job. They did.

The first image shows the Baofeng (notice the wide ‘shoulders’ which shouldn’t be there), the second image is the Anytone. I slightly zoomed in on the Anytone carrier to get a better view.

Harmonics
The Baofeng has no detectable harmonics, the ANILE-8R has one at -57.62 dBm. It’s just short of the -60 dBm I like to see, but nothing to worry about.

TX audio: loud and clear, just excellent. The most memorable quote from a listener was “I can’t tell the difference between this one and your gear at home.”

RX audio: Same story: loud and clear, with no noticeable distortion.

Sensitivity (@ 435 MHz): -125 dBm (@ 50Ω, 12 dB SINAD).

Frequency accuracy of this sample: -26 Hz.

Power output (@435 MHz): 1.2 Watts / 4.2 Watts.

Front-end: good. Unlike the Baofeng, the receiver doesn’t collapse quickly.

Bugs:
I noticed that RX audio muted when I switched on the flashlight. Audio stayed muted while a signal was present. Audio came back after:

• the carrier dropped and returned
• pressing PTT or one of the side keys.

Toggling the flashlight on/off had no influence.

I forwarded the bug to John K3NXU (Miklor) and the owner of Anytone Tech. It didn’t take long before my findings were confirmed. However, a few days later I found an option in the software which caught my eye: “Eliminate Squelch Tail When No CTCSS/DCS Signaling”. The default value was 55.2 Hz. When set to ‘Off’, the strange influence of the flashlight on reception is gone. Problem solved.

Conclusion:
Anytone Tech’s ANILE-8R is a very good radio and can make you forget the Baofeng BF series. Only when I start nitpicking I could make a remark about the belt clip. It didn’t seem to be designed for this radio, as there was quite a gap between the clip and the battery. I solved the problem by bending it a little bit.

Remember that album from Mike Oldfield? A user on YouTube found out that this album contains a hidden and unintentional CW message.

This was caused by a powerful VLF station located next to the recording studio, which interfered with the recording equipment. Because the signal is very weak nobody ever noticed it — until now.

The video below shows you how to receive VLF signals with nothing else than an antenna plugged into the microphone input of your sound card and SDRSharp to make it visible and audible.

The decoding of the the Tubular Bells signal is shown at 9:54.
