Release Version 1.0

Version 1.0 has the same functions as Version 0.95.
If you are using version 0.95 you do not need to upgrade.

Release Version 1.03

Version 1.03 has the same functions as Version 1.0 and 0.95.
If you are using version 1.0 or 0.95 you do not need to upgrade.

1.Changed DVSwitch install script (for new version)
2.Changed the script to be compatible with the new DMR protocol.

• Set default TX/RX frequency to the same.
  3.Apply the new BM Host List (DVPi manager)
  4.Removed BM Host which was set as default.
  (The US1 server, which was previously set as the default, was discontinued in May 2021)

Release Version 0.95

DVPi uses the USRP Client protocol.
When you install and use DVSwitch, you must read and comply with the license that appears. The user is responsible for the license for the use of DVPi.

Version 0.95 is a candidate version of Version 1.0
so, If there are no major problems you won't need to upgrade to Version 1.0.

What was added in Version 0.95 (1.0)

1. DVPi is stabilized.
   The goal is 10 hours of nondisruptive operation, but most of the test devices have been running for more than 24 hours.
   The main purpose of Versoin 1.0 is stabilization

2. Viewing the status of other Talkgroup is now possible again. (bottom line in TG Button)
   I have created a server program that manages the DMR Talkgroup status. Several Amateur radio operator are servicing the server.
   You don't have to do anything for this.

3.ThumbDV settings are now supported by DVPiManager.

4. DVSwitch 1.6.0 is supported if you install DVSwitch on DVPi
   (builtin DVSwitch)

5.There are several minor UI changes.

6.A recording function has been added. It was added in Version 0.88
When you press the record button, the sound output from the speaker is recorded. You can export to Wav file from DVPi Manager.

7. And Minor bugs have been fixed

If not a big problem, this version will be Version 1.0 as it is.
Thank you for using it.

Release Version 0.88

---

DVPi uses the USRP Client protocol.
When you install and use DVSwitch, you must read and comply with the license that appears.

---

Version 0.88 is a test version. If you want a stable version, please wait for Version 1.0.

What was added in Version 0.88

1. D-Star protocol support
   DVSwitch supports DMR, DStar, YSF and NXDN protocols. DVPi activates the D-Star protocol.
   (If you are already using D-Star, you will not be able to use it on two at the same time. If you want to use D-Star in DVPi, you need to log off in another device. If anyone has solved this problem, please tell me)

2.Dual VFO Mode
You can use two VFOs in the same way as a conventional VHF/UHF transceiver.
You can use two DVSwitch servers or DVLink. Or, if you operate DVPi as Standalone, you can create session 2 by copying the existing installed DVSwitch in DVPi.

3.Add expansion hardware

• TX Led
• Function Switch 2
  Function Switch2 can be used as Mode change or VFO change according to your selection.

4.Other bug fixes

Release Version 0.7

Although the test has not been completed yet, no major problems have been found, so we will release it in advance.
Currently attached files can be changed at any time.
If no major problems are found in a few days, Test is removed from the release version name.

Changed in Version 0.7A (changed 0.79 -> 0.7A)
1.When DVSwitch is automatically configured by script, DMR User information is additionally written to DVSwitch.ini (description), MMDVM_Bridge.ini (qrz.com/user callsign)
Thanks DS5QDR

2. Added 1 line 127.0.0.1 dvpi to /etc/hostname
   Thanks G4ZAL

3.Fixed a bug where the sender information is not changed on the screen when the sender is changed quickly (within 200ms)
you have already installed Version 0.79 and you have no problems using it, you do not necessarily need to update to Version 0.7A.

---

Changed in Version 0.79
(For more information, please visit www.hamskey.com)

0.Add a script to easily set DVPi as stand alone (builtin DVSwitch)

1.Several bug fixes

• Fixed an issue where the encoder switch was closed by pressing the encoder switch in the keypad window.
• Fixed the problem that DVPi was not sometimes executed after booting from RPI4
  (I delayed the time to try to connect to the Analog Bridge 5 seconds after booting.)

2.Added Function Button
3.Added Sub menu (+More)
Squelch mode
Unlink function
Auto Log Send ( If you run a program like Log4Om on your computer, the log is automatically transferred.)
Enabled / Disabled VOX
Show RMS for Setting VOX

4.Added VOX
5.CPU Temperature check -> display on main window
6.Voice guidance
7.Quick Menu using Function Key
8.Mode for the visually impaired
9.Separate the audio processing part into a separate thread
10. Show other Talkgroup status

Release Version 0.5

Changed in Version 0.5

1.Talk group change function from the keypad screen to the encoder
2.The DSP function was simply modified for speed, etc.

• DSP to use only interpolation and LPF
• Added gain setting for volume increase when using LPF function
• By default, the DSP function is disabled.
  3.Change font on call sign panel (to distinguish I, J, 1, etc.)
  4.Reserved settings for FUNC1, FUNC2, and FUNC3 extension keys (this is not used, it is only a reserve)
  5.Log record transmission function (using the format used by wsjt-x)
• I know that I am not using LOG because it is DMR communication.
• I applied what I made for my next project.
• It would be nice to use it for net control or memo.
  6.UserDB update function
  7.Added * and # alphabets to the keypad window.
  8.The icons in the Configuration window have been rearranged.
  9.Fixed some bugs

There will probably be no major functional changes up to 1.0. It will focus on bug fix and stabilization.
