John ab6li Hi John, Command 047 simply enables/disables an event trigger. You had to enter the event trigger as 'eee' to make command 047 do something. You might want to run command 045 and then the 'eee' you entered in your 047 command, to see if the 'eee' command is Enabled or Disabled right now. Again, that is the only thing command 047 does is Enable or Disable an event trigger. That action would stop the coutesy tone that would normally fire when the port 3 RX goes inactive. That courtesy tone would also be sent to all connected ports, including port 1. You can email me off-list if you like, and we can go further into fixing your problem. Shorty, K6JSI

Not all radios have bias and not all controllers charge caps backwards. You can solve the problem by removing the mic bias resistor from the radio, I'd like to do that, but I think I just discovered a difference between the MVP Mastr II exciter boards: the Mastr II supplies bias via a resistor connected to pin 11 of U101 (audio processing IC), whereas in the MVP there is no resistor - the bias appears to provided internally within the IC. This is a problem because there doesn't appear to be any way to remove the bias. installing a non-polar cap anywhere in the audio path I suppose that's the only choice I have, but since there's already a 1 µF cap in the controller, the 2nd series cap needs to be a significantly higher value to avoid the combination of the 2 causing another high pass rolloff. or replacing the polar cap with a non-polar. Can do that, but then I have a 2nd big ugly leaded cap hanging off the bottom of the SMC board. Take a look at the schematic I posted earlier, it will suit your needs but I do not program that well, hence the open source of the hardware.

The only problem one does not realize the power savings one might think although it is a noticable amount. The reason is if you look at a MII PA running 100 W its current draw is about 20 Amps. by reducing the power out to 60 W the PA still draws about 15 Amps. Reducing it to 20 W would probably give a current draw of 8 Amp. Just have to try with the pot now in place. It would improve your battery life. If you use a smaller PA as you suggested, MII or Exec II (both can be driven by the MII exciter just fine) a 35 W PA turned down to 20 W the current draw will be noticably lower than 20 W with the 100 W PA.

Hello All, I have a requirement to install a battery backup system at a local ham repeater. It's a GE Mastr II running about 100 watts. With that much RF power, a couple of 100 AH batteries is only going to last a few hours. My first thought was to add a second lower power RF amp (something like 20 watts or so) and use coax switches tied to the AC mains to switch to the smaller amp when the AC power was out. This should give me a factor of 4 or 5 more amount of time on the backup batteries. The second thought (and here is where I need input), was to bring the variable resistor (R8 on the VHF version) from the 10 watt driver board to a smaller external board. Then add a second variable resistor and a relay to switch between the two. This should give me two independent amp settings that can be controlled by a single control. Is there any reason why this should not work? It would save the cost of the second smaller amp and two fairly expensive coaxial relays. The relay could be controlled from the repeater controller or automatically with just a 12v DC wall wart.

[Repeater-Builder] Re: GE Exec II Conv. Max audio 1.5 KHz Dev, how can I increase it
Hi Mathew, You did not mention where you're picking up the audio from the VHF RX. It should be speaker audio, that has been de-emphed. If you are taking it from the high-side of the squelch pot (VOL-SQ HI), that is discriminator audio, and as it has already been correctly pointed out by others, that is still pre-emhed by the users radio. If you send it along to the TX, it will be pre-emphed again there, making the audio double pre-emphed, and it will sound very tinny. One other item to think about. Have you measured the audio level at your pick-up point in the RX? It should be at least 2 volts peak-to- peak for maximum system deviation, usually 5 kHz, coming into the VHF RX. That should drive the pants off your TX. However, if you're not getting that kind of audio level, then you're going to have to adjust the audio level pot, inside the discriminator silver box on the RX. It is the edge-mounted pot. Start with a good audio level, and your TX should be able to deviate normally.

Hate to admit, but I'm not all that familiar about the subject, especially in repeater operation. TIA, Don, KD9PT (Snip) Hi Don, The normal MASTR II receiver uses a low-side Local Oscillator injection for their mixer. The IF is 11.2 MHz, so you deduct 11.2 MHz from the operating frequency. The normal operating frequency for the 88 series MASTR II radios is 450 to 470, so the LO (Local Oscillator) is engineered to run between 438.8 and 458.8 MHz (450 11.2 = 438.8; and 470 11.2 = 458.8). When we in the amateur radio service order a low-side injection crystal, we are essentially asking the LO to operate between 428.8 and 438.8 MHz, worst case being 10 MHz below the engineered operating frequency range (440 11.2 = 428.8, and 450 11.2 = 438.8) This is stretching the original design of the local oscillator 10 MHz beyond the design parameters. If we order high-side injection crystals, we add 11.2 MHz to our operating frequency, rather than subtract it. So the LO will runs between 451.2 and 461.2 MHz (440 + 11.2 = 451.2, and 450 +11.2 = 462.2). If you are operating in an area of the country where you run low-in, high-out split repeaters, your receivers will operate between 440 and 445 MHz, and the highest possible LO frequency will be 456.2 MHz (445 + 11.2 = 456.2), or right in the sweet spot for the LO range (438.8 and 458.8). If you are operating in an area of the country where you run high- in, low-out split repeaters, and your receiver will operate between 445 and 450 MHz, and the highest possible LO frequency will be 450 + 11.2 = 462.2, or only 3.4 MHz higher than the designed frequency of the LO. The cross-over frequency seems to be 448.300 MHz, which is 1.7 MHz higher at a high-side injection than designed, and a low-side injection is 1.7 MHz lower than designed Local Oscillator. So, maybe a good rule of thumb would be to order high-side injection on operating frequencies below 448.300, and low-side injection on receive frequencies above 448.300. That way, the worst case scenario is your being either 1.7 MHz higher or lower than the original engineered design on the local oscillator. You can do the same math for high-band radios. Same IF. Hope that helps.

[Repeater-Builder] SS-64 on MASTR II
In response to Andy's post, This is perfect timing from the ss-64 post. I have a mastr II that I want to hook up a tone decoder to. I have a encoder board already and would like to hook in a separate decode board I dug up. Does anybody have the connection points to hook into? By, the way it is a Mastr II Station repeater. Thanks for the help. Andy KC2GOW The SS-64 wants to be connected to 12 VDC (RED and BLK wires) and the audio out YEL (Yellow) wire wants to connect to the CG HI input on the exciter. Pin 2 on the exciter board. If you want the CTCSS tone to run all the time when the transmitter is keyed, then nothing more needs to be done, except set the tone level, either at small pot on the SS-4, or at the exciter pot for CTCSS. Level should be about .4 kHz (400 Hz). If you want to CTCSS tone to drop off when the repeater receiver or link drops off, then you must de-solder JP-1 on the back of the SS- 64, and hook up the ORG (Orange) wire to an Active Low source, from your receiver, either the COS, or the CTCSS Decode line. If the keying line does not go Active Low but goes Active High, then you need to build a simple transistor inverter circuit to take the Active High and convert it to an Active Low as the SS-64 wants a pull to ground to activate the CTCSS tone (and take a way the ground to make it go away when you stop receiving on the receiver or link). If you want to key the CTCSS tone with more than one receiver, you need to use steering diodes in this ORG keying line. This set up is especially nice for IRLP links, where you don't want to tie up another link radio, but simply use the repeater as the link. It has worked very well for me in several installations. As for the CTCSS decoder board, I usually pick off discriminator audio at the high-side of the squelch pot, the GRN (Green) wire on a TS-64DS. You can make the TS-64DS CTCSS Detect WHT (White) wire go either Active High by doing nothing further, or Active Low by putting a solder bridge across JP-7. Remember to be sure to ground the Hang-up/busy VIO (Violet color) wire, or the decode function will not work. You can also use the TS-64 to encode the same tone as it decodes. Simply hook up the YEL (Yellow) wire to the CG HI input of the exciter. Good luck. Shorty, K6JSI Yahoo!

[Repeater-Builder] SS-64 on MASTR II
Hi There, If you are now using a TS-64 or TS-64DS for CTCSS Decode on your MASTR II repeater Receiver, you can simply use it to send the same CTCSS out your repeater transmitter. However, if not, then you wire up the SS-64 as follows: RED to +12 VDC BLK to Ground YEL to CG Hi ORG to active low from your CTCSS Decoder (if it is a TS-64 or TS- 64DS, that would be the WHT wire, if it configured for an Active Low which means you have the solder bridge across JP7 on the TS- 64. If it is not configured as Active Low then you need to build up a small inverter transistor to drive the SS-64 to an Active Low. You then need to de-solder JP-1 on the SS-64, which will allow the CTCSS tone to drop off when your Active Low from your CTCSS Decoder goes away. That will eliminate the courtesy tone, and the hang- time, on your IRLP Node. You can then program in whatever tone you want to use, and viola, you're working. I have used this setup many times, and it works well.
