I come back with conclusions after experiencing the new Radtel firmware for Abbree 2520. For AR-2520 version V1 (without GPS) the firmware does not work. For AR-2520 version V2 (with GPS) the firmware is perfectly compatible, improves the graphic interface and menus, solves several bugs such as blocking on scanning, channel organization or power on off mode. Unfortunately, there is no improvement in airband reception. We are waiting for a firmware update that will solve this as well.

To anyone looking to acquire commercial radio programming software:
Please do not make requests for copies of radio programming software which is sold (or was sold) by the manufacturer for any monetary value. All requests will be deleted and a forum infraction issued. Making a request such as this is attempting to engage in software piracy and this forum cannot be involved or associated with this activity. The same goes for any private transaction via Private Message. Even if you attempt to engage in this activity in PM's we will still enforce the forum rules. Your PM's are not private and the administration has the right to read them if there's a hint to criminal activity.
If you are having trouble legally obtaining software please state so. We do not want any hurt feelings when your vague post is mistaken for a free request. It is YOUR responsibility to properly word your request.
To obtain Motorola software see the Sticky in the Motorola forum.
The various other vendors often permit their dealers to sell the software online (i.e., Kenwood). Please use Google or some other search engine to find a dealer that sells the software. Typically each series or individual radio requires its own software package. Often the Kenwood software is less than $100 so don't be a cheapskate; just purchase it.
For M/A Com/Harris/GE, etc: there are two software packages that program all current and past radios. One package is for conventional programming and the other for trunked programming. The trunked package is in upwards of $2,500. The conventional package is more reasonable though is still several hundred dollars. The benefit is you do not need multiple versions for each radio (unlike Motorola).
This is a large and very visible forum. We cannot jeopardize the ability to provide the RadioReference services by allowing this activity to occur. Please respect this.
Abbree AR-2520 Software?
- Thread starter mfn002
- Start date
After using this Radtel RT firmware update for a month on my Abbree 2520, I must say it is an improvement but!
There is this problem with stronger signals, at least in my case. If someone is emitting on a close-by frequency, like PMR CH12 and my station is set to receive on CH 6, I hear constant squelch opening and noise, no matter which channel is emitting around. If a signal is strong, I get squelch opened and that horrible noise and it's unbearable. It's like its bandwidth of reception is set too wide to something around 192000khz or I don't know but it is a big mess up....

That is the case with almost every single Cheap Chinese Radio. The front ends are wide open and you get a ton of interference from strong or close by signals. Not a lot you can do about that, aside from buying a different radio.
Please provide a link to the Radtel RT-20M software
I also have the radtel firmware on my abbree 2520. I must say the one feature that i do like is the radio turning on at vehicle start. The abbree didnt do that, i had to manually turn it on.
My biggest beef with both is that you cant import or export cvs files. With 999 channels this is a must!

You are right, bandwidth reception is set too wide that makes the front end overload most of the times. Any idea how to fix this?
My review after using Radtel RT-20M firmware on Abbree AR 2520.
Old CPS does not work anymore nor the Tuning Tool provided in this forum.
Update has made lots of improvement but still there are overloading issues. Airband needs improvement as strong signals gets voice distorted but if you're in parking garage or under some structure which makes signals weak, you will get clear voice on Airband.
Overloading issue is concerned if you are listening on frequency 172.650, and some nearby radio starts TX on 172.850 you will get constant squelch and noise. This much wide bandwidth reception makes the radio front overload most of the time when you are moving in urban city area.
Any idea on how to adjust bandwidth reception?

unfortunately you have to use the radtel CPS , the save formats are different mores the pity. They have different file extensions and a simple rename doesnt work . slowly bit by bit i am having to manually put into radtel format all the channels i had in abbree format. if only you could export and import cvs files
One more thing i noticed when i updated Abbree to RT-20 firmware is that the station becomes slow in terms of procesing commands.
If someone is talking or if there is noise (RX is on) if i press PTT button, station goes wild and emits - im guessing a 1750tone instead of carier signal...and that is a big problem.... Waiting for Firmware update and i hope theyll fix that.
And a question from me for someone with more XP...Is there a way to revert to old firmware?
Just for sports.

Password when set by software is 707070
Did you get anything out of it? Likely you've done the same as me and installed the RT20M update and need the password 707070
I have discovered that you can use the Ruyage UV58Plus setting on CHIRP to program the ABBREE AR-2520, the only problem is that if you copy a set of freqs from another radio on CHIRP it will cause an error if any of the freqs have a "TSQL" in tone mode. Change the tone on any freq with a TSQL to "none", write to the radio, then... open up the UV252 CPS for the AR-2520 read from the radio and then correct those freq to the way you want them, then write back to the radio. It is still easier than manually entering freqs into the UV2520 CPS.
cable pin out it's work for me, i buy cheap baofeng cable for 2 dollar, and my bofeng cable has different color
BLUE GND PIN 3
RED RX PIN 4
YELLOW TX PIN 7
because i have bad eye, quite difficult to crimp it with RG45, so i cut pre made cable + rg45, and connected together.... (white green -> BLUE pin 3) (blue -> RED pin 4) and (white brown -> YELLOW pin 7). and it work well...
