Ham Pager Setup Base on MMDVM

08/31/2018 | RADIO | 没有评论

火腿的第一台传呼机

Ham Pager源于http://hampager.de

寻呼机是多年前,在手机尚未普及时的一种通讯工具,在还有寻呼台的时候,首先我们需要在寻呼台注册。然后缴纳一定的台费和机子费,然后按缴费所购买的时长来提供服务。自从寻呼台相继关闭,曾经寻呼的频率已经清频退网,国内这种服务已经基本不再提供。当然,一些业余兴趣爱好者可以用一定的技术手段来制造一个发射终端,该终端必须在1W以下的功率,因为这个功率范围是免照范围,普通老百姓都可以随意使用。寻呼机最早是摩托罗拉为主导品牌,发展到后期,一些国产的寻呼机在功能和使用性能上已经超越了某些国外品牌。常见的寻呼机编码有两种格式。一种是POCSAG(低速编码),另一种是FLEX高速编码。当然在后期在国内也发明了一些有自主知识产权的编码形式。要想给寻呼机发信息你必须得知道两个基础的信息。第一是寻呼机接收使用的频率。第二是寻呼机的地址码。寻呼机的频率可以通过一些公式计算出来。地址码则需要一定的软件和硬件来读取出来,也可以采用追码的形式追出来(穷举法),寻呼机的地址码最大一般为2097151。

MMDVM Pi-Star to Hampager

Ref: https://hampager.de/dokuwiki/doku.php?id=mmdvm

MMDVM, MMDVM_HS_HAT, MMDVM_DUAL_HAT with Pi-Star (Pi*)

What do I need?

Hardware

  • MMDVM
  • MMDVM_HS_Hat
  • MMDVM_DUAL_HAT

with Firmware >= 1.4.1

Software

PiStar >= 3.4.16 or MMDVM-Host Version ???

Which Pagers can be used

How to set up Pi* for PROCSAC (DAPNET) with MMDVM_HS_HAT or MMDVM_DUAL_HAT

Already have a working installation of Pi-Star (Pi*)?

Yes, I have already a running Pi-Star:

Update and Upgrade Pi*’s base system services and packages

  • Login to your Pi* Installation via SSH using Terminal,cmd-Promt or putty (Standard is „ssh pi-star@pi-star“ (you can miss the :22 at the end, because it is the standard port)
ssh pi-star@pi-star [Enter]

Now you will be asked for the Password – Standard-Password is „raspberry“ without „“ or take the password you have changed in Pi-Star Dashboard.

You will see the Welcome Message in ASCII-Signs

Now you have to Enter the following commands:

1. PI* uses a write protection so the command to unlock the filesystem for editing is:

rpi-rw [Enter]

2. Now get the latest Version of Pi* and all needed software components:

sudo pistar-update [Enter]

3. Upgrade the Pi* Installation to the next following Version:

sudo pistar-upgrade [Enter]

Repeat the last command (sudo pistar-upgrade) till you get a message „you have installed the latest Version of Pi* – No update needed“ or a similar message.

It is not possible to directly Upgrade to the newest Version! So you have to repeat the pistar-upgrade several times.

For example: You have installed Pi* Version 3.4.13 and want to get onto Version 3.4.16

You have to use the command „sudo pistar-upgrade“ 3 times to get from 3.4.13 to 3.4.14, than from 3.4.14 to 3.4.15 and 3rd time to get from 3.4.15 to 3.4.16.

The last output in terminal should be:

    You are already running the latest version…
    Sleeping a few seconds before making the disk Read-Only…
    Finished

Upgrade the firmware of your MMDVM-Hardware

for Upgrading MMDVM_HS_Hat board conected to GPIO you have to enter the command:

sudo pistar-mmdvmhshatflash hs_hat [Enter]

for upgrading the original MMDVM-HS_DUAL_HAT board (made by Andy, Florian (DF2ET) and DB9HAT) conected to GPIO you have to enter the command:

sudo pistar-mmdvmhshatflash hs_dual_hat

If you get a message that the flashing process was successfull, the hardest part is done. If not, repeat flashing or ask for help in the „MMDVM-BM“ or „DAPNET User“ Telegram-Messenger Groups.

Do a restart now with

sudo reboot now [Enter]

Configure Pi-Star and enable DAPNET

If not already done you should register on https://www.hampager.de and than Register a New Transmitter.

You will get a „DAPNET AuthKey“ by email if your ticket is arranged by a Team-Member.

Now it`s time to Login into the Pi*-Dashboard!

On a Windows, Mac, or Linux-based computer (not the hotspot itself) that has WiFi enabled, open a browser window and navigate to (trailing slash needed):

  Windows: http://pi-star/
  macOS, iOS, etc.: http://pi-star.local/
  On some mobile devices, the url won't work. In that case, try the Auto AP IP address: 192.168.50.1

Go to Admin Area and hit „Apply Changes“ somewhere, like if you would save any changes – even if you did not change anything. This will reload the page and force Pi* to reload store and reload the Configuration. During this process all missing or by update added sections will be loaded and shown correctly.

Now you should still see the Configuration view and in the „MMDVMHost Configuration“ section, switch on „PROCSAC“ and then click „apply changes“.

The Page will reload – now search for the „POCSAG Configuration“ section and fill out the needed values:

  • Node Callsign POCSAG – Enter the POCSAG node callsign.
  • Radio Frequency POCSAG – Enter the POCSAG radio frequency. Per Andy Taylor in the Pi-Star User Forum : „If we get good buy in from repeater keepers, we could have a really good paging network with great coverage, especially if we all use the same standard frequency.“ In Germany, where are already a lot of repeaters we use 439.987.500MHz, which will be the deafault entry in Pi*!
  • DAPNET AuthKey – Enter your authorization key for the Decentralized Amateur Paging Network. Which you got by Mail after you registered a New Transmitter as I told you on the Beginning of Configure Pi-Star and enable DAPNET

No Pi-Star installed yet:

Please google for a Pi-Star installation guide. A nice one is written by KE0FHS on https://www.toshen.com/ke0fhs/pi-star.htm or visit the main website of the PI-Star-Project under https://www.pistar.uk/

Testing points on a Raspberry Pi

02/06/2018 | RADIO | 没有评论

Below is a list of test points which can be found on Raspberry Pi 2, 3 and some are also on b+.

With the use of a multimeter, these test points can help with troubleshooting hardware issues.

I have yet to find any formal documentation about these test points. However, I do know they exist.

PP3 GND
PP4 GND
PP5 GND
PP6 GND
PP7 5V after polyfuse
PP8 3V3
PP9 1V8
PP10 Goes from 3V3 to 2V on brownout
PP11 DAC_2V5 (for composite video DAC)
PP12 AUD_2V5 (for PWM audio drivers)
PP13 Goes from 3V3 to 2V on ACT activity
PP14 SD_CLK
PP15 SD_CMD
PP16 SD_DAT0
PP17 SD_DAT1
PP18 SD_DAT2
PP19 SD_DAT13
PP20 H5V
PP21 RUN signal (reset)
PP22 Goes from 3V3 to 2V on activity of green (link) ethernet jack LED
PP23 Goes from 3V3 to 2V on activity of yellow (speed) ethernet jack LED
PP24 COMPVID
PP25 AUDIO_L
PP26 AUDI_R
PP27 VBUS (USB 5V power)
PP28 ETH_CLK (25.000 MHz)
PP29 VC_TMS
PP30 VC_TRST_N
PP31 VC_CLK
PP32 VC_TDI
PP33 VC_TDO
PP34 GND
PP35 GPIO6 of LAN9514
PP36 GPIO7 of LAN9514
PP37 CAM_GPIO0
PP38 CAM_GPIO1
PP39 SCL0
PP40 SDA0

Below is an example of how you can use PP9 to confirm that the regulator is supplying 1.8v correctly.

Ground can be sourced from the SD card slot

And the exact location of PP9;

Adafruit has some great information covering the Raspberry Pi power circuitry. link

八重洲 Yaesu有几款快速充电器CD-41 or CD-30 VXA-10 or CD-15,其中比较常用的是CD-41;

IMG_2646

在使用了一段时间后发现我将手台VX-8DR或者FT-1DR放在充电器上并不能充电,即使将手台或电池从CD-41上面拿下,充电器充电完成的绿色指示灯也是点亮的,也就是Full Charge指示灯常亮故障。

IMG_2669

考虑可能是将手台接触CD-41电极时产生了ESD效应(高电压放电)。

IMG_2670

这可能会导致切换充电回路的P-沟MOSFET (Q2)管子损坏,这个小的贴片原件型号是2SJ204,当然也可以用BSS84 or IRLML9303TRPBF代换,也可以用其他相近参数的管子替代,小心更换。

IMG_2517

 

IMG_2518

更换为新管子后该故障消失,可以正常充电!你不必再花钱去买个新的充电器了!

iCOM IC-7100内部结构

03/04/2014 | RADIO | 没有评论

IC-7100具有一个设计前卫并具有时代感的触摸屏控制器。 IC-7100与其他收发信机,诸如IC7410、9100的设计既有相同之处也有很大不同。通过全面的软件定义,在DSP和编解码芯片完成所有的调制和解调。其他信号处理也可由软件完成。

BDMPA4H(AUH}32IOHYB12DS

模拟设备是放大器和混频器。 带宽,低通滤波是通过分立元件完成,但所有的信号滤波,由DSP进行。

我们看一看印刷电路板。 机械设计很简单。

TX晶体管波段,1.8 – 470兆赫。该晶体管用螺栓固定到一个风扇冷却散热器,从下方看到的,与小信号板折叠到侧面。

IMG_0288

小信号板由一个同轴电缆的RX和TX射频输出,外加两个扁平电缆做其他连接。

IMG_0300

在小信号板PCB顶侧有DSP芯片。 有运行TRX的三个数字芯片。

前言
什么是APRS
APRS是英文“Automatic Packet Reporting System”的缩写,中文译为“自动分组报告系统”。这个名称是发明者Bob Bruninga,WB4APR的注册商标。名称中所指的内容可能会让新手困惑。
首先,APRS是一个通信协议。它定义了数据(包括电台和地图物体位置、气象信息、无线电测向、文字信息和遥测)如何通过无线电分组电台通信。

APRS也指包含APRS信息的网络。贯穿美国,欧洲和一些其他的国家,一个数字中继(“digipeaters”)网络,通常工作在一个共同的全国性的频率,为APRS分组提供传输。通常大部分APRS电台工作在其中一个通常的频道,但是不绝对。
APRS互联网系统(APRS-IS)是一个基于互联网的附属于电台的网络。互联网网关(IGate)通常就是一台能访问互联网的家庭PC和一部电台。网关将电台网络的流量传送到一个共享的、世界范围的APRS流。许多IGate至少会传送文本信息流,一些时候也会传送其他信息。从互联网将数据传回电台网络。用这种方法,文字信息可以从一个电台传递到另一个电台。甚至两个电台间不存在中继器或不在一个中继器的覆盖范围内。
APRS的名称有时候指WB4APR原始的MS-DOS APRS地图程序。但是这个程序现在正确的叫法是APRSdos。目前有数种地图和消息程序存在,使用APRS电台网络或APRS-IS,或者两者均用。一些程序同样拥有IGate功能。
连接到世界范围的APRS-IS流是许多数据库服务。这些系统(findu.com和aprsworld.net是两个最受欢迎的系统)处理、存储所有的APRS数据流,按照转发规则将数据转发到世界上任何一个IGate。大多数系统提供地图、天气显示、基于流量的地遥测图。这个功能允许任何人通过互联网访问监视APRS数据而不需要电台设备或特殊的软件。

当然,将数据上传到web连接的数据库并不是APRS唯一的好处。依靠网络的覆盖和负载,仅使用电台网络完成数百英里范围内通讯覆盖也是可能的。但是,在一个共享网络中伴随着中继器的增加,系统可靠度降低。APRS 最可靠的级别是地区级(LOCAL LEVEL),所以在一个地区使用多于两个或三个数字中继是不明智的。通常情况下,使用一个中继器是最适合本地覆盖的。
APRS协议、硬件、软件可以独立的使用在国家级网络上。本地或临时网络可能因为特殊事件或满足特定组织需要而建立。一些应用可能不需要数字中继。例如高空气球经常使用APRS将位置和遥测数据通过一个专用频率直接发送到搜寻队。
移动使用APRS可以有多种不同的形式。最简单移动APRS设置是一个仅具有发射功能的追踪器连接一部电台和一个GPS 接收机。这些追踪器通常没有接收功能,除了在发射前追踪器会检测频道是否被占用。追踪器允许自己的车辆被他人追踪,但是无法接收信息或者位置。
另外一种选择是一部具有APRS功能的电台,例如Yaesu vx-8R,FT-1D。这些电台有一个文字显示屏,但是需要一部带有地图功能的GPS接收机显示位置和其他电台。
一部普通电台配合TNC与一部笔记本电脑或PDA结合使用可以提供完整的APRS功能。包括地图定位、消息功能。虽然这通常是最贵的配置而且在驾驶的过程中操作不方便。

用简易图示说明如下:

移动手台–>发射调制的数据信号—>基地台并连接互联网—>(http://aprs.fi等网站追踪行程及位置,接收message)

当然这个过程可以逆向,也就是说可以利用互联网向数字手台发送Message

目前APRS系统使用的频率有公约划定,亚洲中国分配频率是144.640MHZ,当然也可以使用任何其他业余频率,甚至是HF,这样可以有更广泛的电波覆盖。
