Ronnie Steve Rice wrote: Hi all, I have been fighting with a problem now for 2 days and must be missing something! I have a micor repeater with a Station card and a ICS controller and I am triggering the controller cos from the Squelch Ind pin 5 on the old squelch gate board connector. I am using the Ptt out to the rptr PTT with a mosfet to ground the transmitter osc. Discriminator is coming from pin 10 of the old Squelch gate Card connector. Now here is what is happening 1. Trip squelch Pin 5 goes high 2. Ics Controller trips repeater 3. Receiver Pin 5 goes low and stays low until transmitter unkeys Of course that keeps the transmitter keyed until I manually unkey the radio. I also notice that there is no audio from the receiver either. If I put the squelch gate card back in and a station card everything works fine as far as keying and repeating. Maybe something is telling the reciever to stop or rf is getting into the receiver somehow shutting down the squelch ind. Any help or thoghts. Thanks Steve The problem seems to be with the way I am connecting the controller as it is being a real pain! Not sure it is the controller yet but will have a good idea tomorrow or Sunday as I am going to try an alternative. I am using Carrier squelch to test with before hooking up a tn34 board for tone. The ICS controller is the Single M and the vote is still out on it! Being one of the original design engineers, and the originator of the concept of the SingleM, I can assure you that it will properly interface to your Micor. While it's specifically designed to interface to the Mobile Micor, there is no reason why it won't work in a Station. That being said, I have no vested interest in ICS Controllers other than lending a hand to help. I don't get paid to help, as I'm simply a volunteer. Ronnie, A few questions, before I offer suggestions. 1. What cards are you using or would like to keep in the Station? 2. Are you doing anything special that requires the Squelch Gate Card? (like Spectra-Tac voting?) 3. Are you opposed to starting over where your wiring is concerned? 4. Does your Station presently have OEM PL tone encoder and decoder boards installed? 5.

Kevin Custer Hi Kevin, Well as I stated earlier here I am of the belief that the problem is in how I am connecting the controller not the controller itself.

I have narrowed the problem down to the audio/squelch board cutting out squelch indication when transmitter is tripped. Here is the setup 1. Receiver was PL but PL board removed and Jumpers installed in Audio/Squelch Card per the manual. 2. Pl defeat switch set to disable PL 3. Keying is accomplished by the controller keying Rptr PTT line 4. A MOSFET is set to activate from A+ grounding A- and F1 Transmitter element. (So element doesn't run all the time) 5. Audio is taken from the station control disc out and is fed in xciter audio. ok originally this was a PL repeater,remote base and it now works fine on carrier squelch when I install the Squelch/gate card, Station Card, and Line Card. When I measure the voltage coming from the Receiver audio squelch board where I would of expected to connect the cor input I see a squelch change on pin 9 (Rec Act ind I was told do not use this pin) and pin 13 (Rec Unsqulch ind. this is the one I have been working with) of J2. Everything is fine when I open the squelch or close it I see a change. When I open the squelch and key the transmitter the voltage on pin 13 and pin 9 revert to the unsquelched mode which of course tells the controller to reset the transmitter. It is like the keying the transmitter is removing ( or supplying) some voltage from the squelch board so that the receiver audio squelch goes mute.

Lunar, Janel, Angle, ARR are all excellent preamps. If your repeater is on UHF, the phempt designs are the latest and greatest things going.

[Repeater-Builder] Re: Micor and ICS SingleM Controller
Well Kevin seems the one receiver had the diode removed and I (ASSUMED) that the other one was removed. I do have the ICS controller connected but added a npn transistor between the squelch shunt and the controller as a follower. I have a voltage swing of 1 to 10 volts with the squelch. I notice that the controller does not respond every time when the squelch breaks and am still looking as to the reason. just stops seeing the voltage swing. I check with a meter and it is swinging fine. COS Pot doesn't seem to make much difference where I set it. Well let me double check later this evening as I stared at the project so long I was overlooking an obvious diode. Glad you mentioned it sounded like it needed to be converted so I double checked the receiver diode first thing! Thanks Steve Yahoo!

Re: [Repeater-Builder] UHF Preamplifier
I've got the same setup. I also have a 4-section Celwave bandpass filter between the duplexer and preamp. I found that the 17dB gain was way too much for the receiver, and the noise level increased dramatically, to the point that I had to tighten the squelch settings. The sig strength metering went from 10 to 14uA with no signal. I ended up putting 7dB of attenuation between the preamp and the receiver, but still had too much gain. I later increased to a 10dB attenuator. The receiver metering is resting at about 10.5uA, the squelch got reset to what it was with nothing connected to the receiver at all, and there's just enough gain to offset the losses from the coax, duplexer, and filter, and still leave some for the received signals. If you aren't padding the preamp output down, you should seriously consider doing so. The preamps are made with all that gain so you can feed a lossy multicoupler with them; when feeding one receiver, you don't need or want all that gain.

Think about this for a minute, if the noise level increased, the squelch circuit would have seen MORE noise and rammed the squelch closed. What actually happened is, adding a better device in front of the receiver lowered the receivers total noise figure, decreasing the noise in the squelch circuit, requiring the squelch pot to be set tighter. Very common effect. Kevin Yahoo!

Re: [Repeater-Builder] Re: DR-235 for repeater
John, I may be wrong in my assessment. By One-Way, I was referring to rig to TNC. By 2-Way, I meant taking discriminator out of one rig to discriminator audio in of the other and vice-versa. Everything points to the audio being unconditioned, thin and aurally pure, but when you send it to the other radio, destined for rebroadcast, the receiving radio does the conditioning. I'm not sure if my choice of wording is technically correct. The results we have had in playing around with the data ports were not what we expected. The term Conditioning was the best I could come up with for the transition of discriminator output of the Transmitting rig being injected to the discriminator of the Receiving rig and the final result coming through the speaker. I once heard that the best preamp in the esoteric audio world would be a straight piece of wire; with gain. However, in the real world, every audio device does some conditioning to make the output pleasing to the ear. This practice probably goes back to the Fletcher-Munsen curves, which were the result of early pioneering in the Bell System to determine the best response curve for telephone headsets. Their results have been used on many ways to augment the human listening trait. OTOH, the discriminator has always seemed to be the best point to tap to get audio that is not colored in any way so as to be the best choice for analog input data transfer. I think Ken's reply summed it up in far less words.

When coupled to the second rig, the conditioning takes place.? Which output are you talking about? I guess my question is: Other than the specified signal levels, what IS the difference between the 1200 baud audio out and the 9600 baud audio out? de WD7F John in Tucson - Original Message - From: [EMAIL PROTECTED] To: Repeater-Builder@yahoogroups.com Sent: Saturday, December 17, 2005 9:57 AM Subject: Re: [Repeater-Builder] Re: DR-235 for repeater I also had the same concerns. However, I found that the treatment after the discriminator on the respective radios applied the conditioning to make the interface transparent to the ear. We have tested in-band range extenders using antenna separation to extend the range of simplex communications by using a pair of 2 meter rigs connected data port to data port. I have also done similar experiments going from 6M SSB to 2m Simplex and back. The audio quality does not have the thin quality you would expect; reinforcing the concept that the radio does the conditioning after the discriminator to the user interface (speaker and audio controls on the receiver). It took me a long time to finally accept that this was the case before even trying to use the data ports for user audio. On a one-way setup, you definitely get discriminator output. When coupled to the second rig, the conditioning takes place.

Has anyone looked at the audio flatness of these ports? Also, some rigs have a 1200 baud in/out and a 9600 baud in/out, which (apparently) have very different audio levels. I suspect there are other characteristics that are different, too. 73, Bob K0NR --- In Repeater-Builder@yahoogroups.com, [EMAIL PROTECTED] wrote: Andy, I have not personally done this, but the data out connector should suply pins for audio in , audio out, Squelch voltage or logic and a reference ground. These signals should provide everything you should need for direct linking of 2 radios. The DB9 is easy to work with. Since these were designed for packet use, the audio is not affected by front panel controls. It is conditioned and altered after it enters the TNC; or in this case, the other rig. I have set up crossband repeaters using data connectors from other brands, and it works well with little external manipulation.

RE: [Repeater-Builder] UHF Preamplifier
Like others have said, Lunar doesn't exist any more. Angle Linear is the current company, and Chip Angle makes great products. However, if your ARR is working, you are likely not to experience any measurable improvement in performance by switching to something else (assuming the ARR you have is a GaAsFET). Personally I like Angle Linear's preamps a) because they work well, and b) I've never had one fail out of probably 30 or 40 in service on various bands, both ham and and otherwise. YMMV. And as others have mentioned, proper filtering before the preamp is almost always necessary (pass/reject duplexers often aren't enough). --- Jeff -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of mdnosliw Sent: Saturday, December 17, 2005 11:18 AM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] UHF Preamplifier I am currently running a AR2 preamp on my MSF5000 repeator with a cellwave 526 duplexor.

Re: [Repeater-Builder] Re: Micor and ICS SingleM Controller
Well Kevin I sent some questions to the ICS group but pretty much got all the answers by playing with a touch tone pad and some wires so I could program using the Cntrl input. Messages aren't approved yet so don't show up on the group ! What I found is there are 2 errors on page 10 regarding Pin description on PL1. Pin4 is not audio for the Cntrl Rec(it is gnd according to schematic) and pin 7 which is labeled Cntrl rec cos input(schematic says it is the squelch wiper) . That was for my book that just arrived a week ago. As for the connector I also used a 10 conductor stranded hard drive ribbon cable. I figured it would look nice and neat when in the cage. All my connections are from a blank micor card plugged into the old Squelch/gate slot. I had planned on mounting the controller board to this blank(except for the Mosfet for transmitter on it).. This way I can just pull out the controller and plug original boards in and the repeater should come back on line. All the connections come to the backplane at that point. (Does require removal of the audio jumper wire on the receiver pins.) As far as some of the mods that you linked I meant that some of them I liked and will probably do but some that require major changes I probably would not only because I like the idea of being able to plug any station card in,receiver,etc. and be back up. I will be doing the squelch mod for sure! Not that it is better or not just a different way. I did notice that a resistor was required on the cos input to a+ because when the line card and gate card are out voltage dissappears from the pin 8 of the receiver. The resistor just gives some voltage for the pin 8 to sink on squelch or not. Again the resistor is also on the blank card so when the card is pulled it can revert back to original. ( not that I would) I see where the controller will probably be great for the mobile version! It has the squelch pot and controls right there! I will call digikey this week (well maybe mouser) and order new connectors and pins. I did comment to Brian that they should ship the controller with all the connectors so that no mater what the configuration the connectors would be there. Like when I hook up the tn34 ctcss module. No connector so have to wait until I can order one. Brian said he would send one but also gave me the part number. All in all with your help I do have a repeater ready for testing. Just have to turn off the ID every 5 minutes or so. More reading. Thanks for the suggestions and help and maybe I won't use ribbon cable on the connector next time! Time for me to take a break and watch so TV!
