I was married in 2015 to my wife Frances; subsequently, my mother passed away in 2016.  Two days after her passing, I received a call that my wife had chrondrosarcoma in her left leg and pelvic region. A slow growing but agressive type of cancer; she survived but we are always vigilant regarding its return.  All of this was compounded by a revocable trust family lawsuit and completing my Ph.D in 2019 at the University of Arizona with credits transferred from Columbia University, New York, New York.


Many thanks to MD Anderson Cancer Center, Houston, Texas; my sister Cynthia Ann Gabrielson Lurix, Sealy, Texas and W. Robinson Frazier, ESQ, Jacksonville, Florida.

Bridgecom BCR-50V/RC-210 controller 2 meter repeater is operational.  Uplink 144.580, Downlink 145.180, PL tones up and down 103.5, FM analog.  Allstar operational


BCR Repeater Connections:

When programming the BCR, make sure the PL tones are the same for both SYS-OP (slot 00) and your repeater slot (01).


The following are the jumper settings for the RC-210 to work with BCR 50V; I have the connection through Port 1:  Set JP1 (CTCSS) to active LOW and JP2 (COS) active HIGH.  Now with the RCP programming menu enter the Port Switch tab.  Make sure the following are checked for the port you are using: Transmit Enable, Receive Enable, under the Access Mode pull down menu, choose Tone & Carrier.  Below this the following must be checked: DTMF Enable, DTMF Required Tone.  On the righthand under DTMF Evaluation On Close, enable COS, Tone Encode Polarity is LOW.

RIM-Lite to RC210 Connections:

Download the Allstar image here:



Enter your router settings and forward these ports associated with your node IP address:

UDP 4569 TCP 222 or UDP 4570 TCP 223.


You will need a 16 GB micro SD card.


Download Belena Etcher here:



Allstar will only run on a Raspberry Pi which uses a Debain-based ARM (32-bit) architecture; there is not a Windows version.  Insert the micro SD card into the boot slot of the Raspberry Pi 4 Model B.


Upon booting the Allstar image enter the following, login: root, password: root


Set the following jumpers in the RC-210 for the port you are using:  CTCSS remove this pin, COS is set to active LOW.


Using the RCP programming software for the RC-210 perform the following.  Under the MACROS tab on the first line (Macro 1) enter 118   Macro 118 will link Port 1 to Port 2 (BCR to node).  Now restart the controller.  Macro 1 is automaticlly executed upon controller startup. You can place other macros on line 1 as well such as macro 181, play voice ID. Each time you add a macro to line 1, you must restart the controller.  Any macros to be executed below macro 1 will can only be enabled by using DTFM commands or the schduler in the RPT.conf. Now under the PORT SWITCHES tab make sure Transmitter Enabled and Receive Enabled are checked. Under the pull down menu for Access Mode use CARRIER.  Do NOT enable any DTMF switches below this menu.  On the righthand side under DTMF Evaluate On Closure, make sure TONE is enabled for your port and Tone Encode Polarity is LOW.



Now you have to edit the simpleusb.conf file for the node to work correcly.  Returning to the Allstar menu, enter the BASH shell and go to the root directory cd /.  Now enter cd / then cd /etc/asterisk and execute the VIM editor: vim simpleusb.conf and hit the INSERT key on you keyboard.  Now we edit the parameters for this file:


;General USB




;Receive parameters









;Transmit parameters









Press ESC then SHIFT+: enter w (write), again SHIFT+: enter q )quit.



In the same directory enter: vim rpt.conf and press INSERT on you keyboard.  Edit the following parameters:


;First Node Definition

[enter your node number here]


;Channel Driver Settings



;Repeater/Simplex Settings



;Node Lookup Methods



;Context Mapping

controlstates=controlstatesXXXXX ;XXXXX is your node number


;I use CW ID










;Skip down to audio settings

;Audio Level Settings


telemduckdb= -9


;Dial Plan Settings


callid=Repeater <enter your node number here>



;Skip down to misc settings

;MISC Settings




Press the ESC key then SHIFT+: enter w (write) and SHIFT+: enter q (quit)


Now cd / then cd/etc/asterisk and enter vim iax.conf.  Make sure in the general section you have this paramter set:

register=node:password@register.allstarlink.org so for example:

register=547272:my password for allstar@register.allstarlin.org

Also the bindport=4570 (put the port number entered in your router).

bindaddr=the IP address for the node as entered in your router.


Press ESC key then SHIFT+: enter w (write) and SHIFT+: q (wuite)


BCM-220 Link Radio to RC-210 Connections:

The following are the jumper setting for the RC-210 to work with a BCM link radio; I have the connection through Port 3: JP5 (CTCSS) to active LOW and JP6 (COS) to active HIGH.  For Port 3 the RX audio is JP9 which set to FLAT/removed.  Also, when programming the RC-210, in the PORT SWITCHES tab make sure the link radio is set for CARRIER only, disable DTMF.  Finally, link the port for the link radio to the port on the BCR/RC-210 port using the RCP programming software.  In my case, port 1 is linked port 3 using macro 119 with courtesy tone 1, macro 69 for port 3. 220 link radio frequency is simplex 223.640 with CTCSS 103.5.  As a programming note it is best to place macro 119 on line 1 under the MACROS tab.  For example, my line 1 reads 118 119 181; line port 1 and 2; link port 1 and 3, play voice ID.

NOTES Regarding the Icom ID-5100A transceiver.

How to add your own hotspot for D-Star use.  Make sure you are in VFO mode.  MENU->DV Memory->Repeater List.  Scroll down to a SEQUENTIALLY empty group number (I am using number 22).  Touch on the empty group and add the following information: For the name I use my hotspot name such as pi-dstar.  Enter you call sign making sure you have exactly 8 characters; e.g., mine is KM7KK  B.  I have two spaces between the last letter in my call sign to the module. Use module C for 2 meters, A for 1.2 GHz and B for 70 cm.  Enter the frequency of your hotspot which is a simplex device.  For the Use From parameter enter YES.  But for offset mode use only DUP+ and the offset number to 0.000.00.  Why this is the case, only the Icom gods know for sure.  To everyone, it makes absolutly no sense.  Finish up by entering your time offset from UTC.


I you want to use the ID-5100A with an external GPS, DO NOT USE THE OPC-1529 cable as stated in the manual; it absolutly will not work.  The two data connections for the RS-232 are backwards.   Make your own cable  ensuring ground (GND) goes to pin 5 on the RS-232, TxD to pin 2 and RxD to pin 3.  The GPS diciplined oscillator I use is from BG7TBL.

Below:  This is my first QSL card when my call sign was WA2MKD in 1973; I was 20 years of age.  I found the photo on eBay. I lived in Summit, New Jersey but operated a portable station in Mantoloking, New Jersey.  My good friend and the person who mentored me in amateur radio, George P. Slockbower, W2PHB lived across the street from me in Mantoloking. George passed away in 1989 but his interest in amateur radio and legacy live on through me.  Thank you George, you will always be remembered.
