[Repeater-Builder] Help! Need information
Good Morning! I hope someone can tell me or help guide me in the right direction for some information. I've recently placed a repeater on the air and need help with something small. I best give all the details of my repeater as the type etc. The repeater is a converted mobile GE MASTER II UHF 440 Mhz MC65KKG88B or ( BROWN HANDLE MODEL), I have a NHRC 3/M2 controller and also the NHRC VSQ unit installed . I have a wiring harness that plugs into the main body of the radio. I don't need a control head with the controller installed internaly. What I'm looking for is some information so I can bring the audio connection to the out side of the repeater and loose most of the control head harness minus the audio leads for the speaker connection. Simply put, I want to get rid of some of the bulky wiring and have only what I need out side the repeater. I will post some pictures of both my simplex repeater and duplex repeater on the site. Please! any information or guide me to where I can find this information would be a big help. Thank you. 73 de KB4ZGO/Tony Yahoo!

Re: [Repeater-Builder] Help! Need information
You need a COS signal of some sort from the radio. As an engineer I recommend running the NHRC-2 in conjunction with a NHRC-Squelch. This will take the "RX data" signal and give you a carrier detector without any modifications to the radio. But you will need to make sure that this "RX data" is unprocessed audio from the discriminator, in order to get the high frequency that the squelch board desires. Check your manual. Then you would configure your NHRC-2 to de-emphasize the "RX Data" audio as well, unless there is no processing done to the "TX data" line, then you would not de-emphaize the audio, just run it through the controller. Basicly if you got this far, experiment until it doesn't sound "Tinny". Of course you could save the low cost of the NHRC squelch board and reclaim one of the unused pins of the radio connector and find the radios COS and give it to the controller, but this may void your radios warenty.

Do you think I will be able to interface these two items together Have you thought about how you are going to get the CAS from the Alinco to the controller? I guess you could always use VOX. Did you plan on tapping inside the radio for CAS and bringing it out through one of the unused pins? Tedd Doda, VE3TJD Lazer Audio and Electronics Baden, Ontario, Canada Yahoo!

[Repeater-Builder] Help! Need information
Hello folks, I'm in need of some help. I have ordered an Alinco DR-135TMKII which has a DB9 connector on the back for packet. I saw this site http://www.maxentropy.net/radio/amateur_radio.htm#top This person was able to interface an NHRC 2 to the Yaesu FT1500M through the 6 pin din plug on the back of the radio that is used for 1200 baud packet. I would like to do the same thing except using an ALinco Transceiver.I know I've been asked why would I use a new radio for a simplex repeater instead of a good used rig. Well it's rather simple I could use an older radio and interface it with the NHRC 2 controller, but I would not be able to use the micropone while it was connect to the controller. With the new radio installed in my truck and controller conected to the radio I could use the radio normally and when the controller is needed just throw the switch and BINGO! emergency repeater. Now I should mention that I plan to use the same model controller as was used with the Yaesu FT1500M. The NHRC 2 has a DB9 connector also and here is the pin out for the controller. Pin 1 ground Pin 2 13.8 volts Pin 3 PTT ( active low) Pin 4 Tx audio Pin 5 RX audio Pin 6 CAS+ Pin 7 CAS- Pin 8 gound/Tx audio Pin 9 ground/RX audio Here are the pin out for the DB9 connector on the Alinco Transceiver. These will also be through the 1200 baud connector set up. PINS 1,2,3,6,and 8 not connected Pin 4 RX data Pin 5 ground/sheild Pin 7 PTT Pin 9 Tx Data So! Do you think I will be able to interface these two items together and fuction as a simplex repeater as KE6DAX did with the Yaesu? I hope so, because there is a need for such a device in my area in case the local repeater is down and something is needed. I'm also working on getting my own repeater up and running also so if it ever goes down I'll be able to trun on the switch and BINGO! temporary emergency repeater is active till I can get my repeater back into full service. I'm serious about wanting to have an emergency back up repeater and the simplex would be the answer to a problem . Just check out my website http://home.earthlink.net/~kb4zgo/ and take a look at the family photo of radio on my site. Well enough of my ramblings. Please let me know what information you have or suggestions thanks 73 de KB4zgo [EMAIL PROTECTED] Yahoo!
