I suppose it could but that would make no sense because the receiver uses this high freq noise to operate its own squelch. You may want to play with the squelch setting a bit. GeorgeC A typical hardware squelch, using, for example, the MC3361, takes the output of the discriminator puts it though a small capacitor (which acts like a high pass filter) and runs it through a "noise amplifier" before applying it to the level detector. The discriminator output of this same detector circuit taps off before the noise amplifier and will likely have some low pass filtering - intended to scrape off the 455 kHz AC - but probably will reduce the level of signals in the 10-20 kHz range somewhat...

OK, FB. To each his own I suppose. Another downside with the DSP squelch is the inability to do DPL. 73 Kyle K0KN Olathe, KS --- Original Message --- Date: Sat, 30 Mar 2013 09:51:36 -0400 From: "Pierre Martel" Subject: Re: [App_rpt-users] Something is rotten in the state of Denmark I really like the idea of ctcss decoding on the fly.

I'm just reading this thread, so forgive me if I missed something, but can you use COS and filtered, muted audio rather than discriminator audio and DSP? Personally, I prefer the former, especially when using Motorola 16-pin radios, where all of the signals you need are already at the rear panel. With this configuration, you can use SimpleUSB and lower your CPU usage by not running the DSP routines. I agree that sometimes the weak signal squelch detection isn't as accurate as COS. 73 Kyle K0KN Allstar 2210-2219

And what you have cut and pasted below is a station operating as a beacon station. Not a repeater station sending “CW (modulated interrupted tone) or voice” by frequency modulation (FM). Beacons are used for propagation determination on 10, 6 and 2 meters. Although I have never heard a 2 meter beacon station. Have you ever heard a beacon station on 10 or 6 meters? When 10 meters has propagation, I can hear 100s of them. A beacon station transmits A1 (CW). Not F3 (FM) or CW by modulated FM. 73 Jim W7RY From: ALERTradio ERC | N0PCO Sent: Friday, March 29, 2013 9:02 AM To: Jim W7RY Subject: Re: [App_rpt-users] How to turn on AllStar ID Requirements On 03/29/2013 09:57 AM, Jim W7RY wrote: Please point me to the part 97 rules that state beaconing is illegal. 73 Jim W7RY § 97.203 Beacon station.

Hi all, Just wishing you all a Happy Easter from Down Under, may you have a safe and wonderful holiday, and may we all have working radio networks at the end of the break...! Mine is still in pieces, I'm yet to try Anthony's AllStar on kernel 3.x modifications. And solder up a cable for my Simoco. Be well everyone! Happy Easter!

Goerge, if you take a look at the receiver part of the mrs 2000 you will see that it connect to the back plane by a connector, those connection then goes to various part of the repeater for filtering and tone detection on vairous different cards.. I take the audio signal directly from pin 5 of the receiver board. I dont see any filtering on the reciver board. In fact from the service manual that you can find here (for the vhf receiver) http://www.repeater-builder.com/motorola/msr2000/pdfs/vhf-msr2000-receiver.… on page 7 there is a block diagram of the receiver and we can easily see that there is no audio limitting and or filtering at all on the board. Nad the leevl that I can see on my scope is pretty close to 250 mv as stated on the service manual.. I think that the trouble is with my settings.. I am working on the 28739 node. here is my usbradio.conf file [general] [usb27821] hdwtype=0 rxboost=1 txboost=1 rxctcssrelax=1 txctcssdefault=103.5 rxctcssfreqs=103.5 txctcssfreqs=103.5 ;rxctcssoverride=0 carrierfrom=dsp ctcssfrom=dsp rxdemod=flat txprelim=yes txlimonly=no txtoctype=no txmixa=composite txmixb=composite invertptt=0 duplex=0 rxondelay=1 rxnoisefiltype=0 eeprom=1 [usb28739] hdwtype=0 rxboost=0 txboost=0 rxctcssrelax=0 txctcssdefault=103.5 rxctcssfreqs=103.5 txctcssfreqs=103.5 ;rxctcssoverride=0 carrierfrom=dsp ctcssfrom=dsp rxdemod=flat txprelim=yes txlimonly=no txtoctype=no txmixa=composite txmixb=composite invertptt=0 duplex=1 rxondelay=0 rxnoisefiltype=1 eeprom=1 I did not touch the 27821 one since I put it down to use one main controler not a machine connected to port 3 of our rc210, so I know its not ok.. when i try to tune the base noise.... ve2mrc*CLI> radio active usb28739 Active (command) USB Radio device set to [usb28739] ve2mrc*CLI> radio tune rxnoise tune rxnoise maxtries=12, target=27000, tolerance=2750 tries=0, setting=2, meas=1754 tries=1, setting=16, meas=16505 tries=2, setting=16, meas=17517 tries=3, setting=16, meas=15942 tries=4, setting=16, meas=15816 tries=5, setting=16, meas=16604 tries=6, setting=16, meas=17943 tries=7, setting=16, meas=17805 tries=8, setting=16, meas=15489 tries=9, setting=16, meas=18234 tries=10, setting=16, meas=16747 tries=11, setting=16, meas=17647 DONE tries=12, setting=1000, meas=17647, sqnoise=5040 ERROR: RX INPUT ADJUST FAILED. then I set rxtone and rx voice. but I have a long tail of noise (about 500 ms) before it stop then I have no sound and the courtesy tone.. I never saved my settings before making test, would that be the problem? do i need to save the settings every time I adjust the system so that the settings are used in my test? From: George Csahanin Sent: Friday, March 29, 2013 2:33 AM To: Pierre Martel Subject: Re: [App_rpt-users] Something is rotten in the state of Denmark Pierre, are you sure that you are getting wideband noise to the usb device? Before de-emphasis? I am looking at a manual for a MSR2000 and it shows a "variable gain amplifier (U1) which feeds the squalch detector, but alsdo feeds a low pass filter on its way to the noise gate and also feeds a de-emphasis network (U2). Any audio after that cannot have enough hi frequency component to make the setup for tune rxnoise work properly, which will not let the squelch work properly. The long squelch tail you refer to is usbradio not having its squelch set properly. And that cannot be done without wide band noise in. The result would never have enough hi freq noise at the uri to actually squelch the radio. What is eventually kmuting it is the end of input PL tone... Just my thoughts, but I have never had my hands on a MSR2000. I own one, just haven't received it yet.

Still with my project to have a full App_rpt controler for my 2 repeater system. I manage to have our msr 2000 in the shack today cause the exiter is giving us some trouble. so I said, lets fix the exiter AND plug in the URI so that I wont have to do this on site. exiter is ok, well for now... So I connect the URI pin 22 (mic AC) to pin 5 of the receiver inside the msr2000, why 22 there is a big dc bias at this place so uning the mic dc would nt be wise, I beleive.. now I go to the computer set active radio usb 28739 now I do radio tune rxnoise.. It fail. there is at leat 200 mv of audio there. changed rxboosst in usbradio.conf for that node, reload, no difference. still did the radio tune rxvoice and rxtone. then tested without saving , I have a big white noise at the end of every receiption before the coutesy tone.. what Am I doing wrong?

How to turn on AllStar ID Requirements
by George Zolla 29 Mar '13

29 Mar '13

I am new to AllStar but I have great little home AllStar node with a simplex base station radio set at 5 Watts. No one else has ever connected and i ti meant just for my use. As such I do not send out a station ID at regular intervals. Now I am helping a friend set up an AllStar site that will be used initially by an ARC then hopefully will get even wider use. At present we are using a simplex base station radio at 25 watts. One of the club members has suggested that we need to be sending out an ID every 10 minutes while the station is being used. Is this correct? If so, how would I trigger that in AllStar? I have looked pretty closely at the rpt.conf file and have read throughout he documentation. I doubt that we want to turn on the beaconing. All other lines of code concerning links and morse code are are still at the default settings. Is there a line of code I need to uncomment or add to enable this feature? Thanks of your help! George, K6GAZ
