Re: [Repeater-Builder] Complex Skywarn Paging System
Off the top of my head, one Repeater here does full POCSAG meaning anyone can get a real old fashioned UHF pager with the group and individual CAP codes programmed into it and receive full text messages. Messages can be sent via a DTMF cheat sheet that allows the full ASCII character table via a phone call to the Repeater controller or someone built a VB app to translate from text using any standard modem by having it dial up the controller and do the necessary DTMF. Not sure if you'd call it paging, but there's another local system with 6 or 7 121.5/243.0 airport ELT monitors that listens for a multitude of DTMF sequences from those monitors to trigger an alert mode, add a second CTCSS tone to the output, and voice announce which airport is alerting, while also opening and closing audio from the mountaintop 121.5 and 243.0 receivers inbetween search team transmissions. The individual monitors also speak the airport identifier, the alert frequency and the relative signal strength in uV. The whole DTMF ball of wax is monitored by an off-mountain Linux box with a receiver on the Repeater's output and hardware DTMF detector for doing secondary alerts via email/SMS. -- Nate Duehr Sent from my iPhone On Feb 15, 2009, at 23:14, dallasreact112 dallasreact...@yahoo.com wrote: I am just curious if any other amateur 2 meter repeater has a more complex RACES Skywarn paging system than the 146.88 W5FC Dallas TX repeater?

[Repeater-Builder] Suggestions for Gel Cell Charging - Large Array
I have a site which seems to be at the bottom of Idaho Power's to-do list when it comes to outages. The last major service interruption for for 8 days. Previously, our repeater was piggybacked on a commercial user's battery back up which gave us working power for about 3 days (duty cycle on the commercial gear was much higher than our equipment). That company has since gone belly up and removed their equipment and back up power leaving us with nothing but AC to rely upon. I've inherited several dozen Gel Cell batteries previously in use for CATV line equipment power supplies. These are rated at 85-90 amp hour. Our plan in the spring is to put 10 of these up on the site for roughly an 800 amp hour array, with plans to go up from there. The vast majority of the Ham plans I've seen on the web are designed for 7-12 amp hour Gel Cell charging at a rate of less than 1 amp. Is there an a relatively inexpensive method of charging these batteries without completely breaking the bank? I know in a recent conversation here on RB, one of the users had a Solar Charge Controller inline between his 12 volt power supply (in our case a GE Mastr II 30 amp supply) and the actual repeater equipment. Any *useful* information is much appreciated HI HI :) 73s, AJ, K6LOR

[Repeater-Builder] O.T. Solar Charger Problem
Here is what I have: 212 watt solar panel PS-30 Solar Charger Controller two CAT batteries This system has keeped my repeater up and running with no problem until two weeks ago. Went to the site and found small bugs, about 1/8 long packed in the solar controller around the power transisters. There was no power coming thru the controller. We cleaned the bugs out. Hooked the controller to a power supply and a battery. It worked just fine; it charged the battery. I took it back to the repeater site this last Saturday. It was coudy but it was passing 12.80 volts to the batteries; therefore charging. I turned the repeater back on Sunday about 1:00pm. Then later Sunday night the repeater stopped working. You are asking yourself what was the battery level before turning the repeater back on? Sorry I did not take that reading. When I left the site on Saturday, the battery level LED on the charger controller said batteries were atleast 3/4 full. Before leaving on Saturday I put a screen ove the vents in the cabinet to keep out the bugs. Yes I removed the bugs that I could find. I removed everthing from the cabinet to do this. I am going back up today to see what I can find out. Any suggestions on what to look for? Thank you. Rod kc7vqr
Re: [Repeater-Builder] Suggestions for Gel Cell Charging - Large Array
These units are very popular with RV boat folks. I have the 60 amp version in my truck camper, I am very happy with it. By what I can determine, it will give a full charge in about 8 hours. I have it feeding a 190 AH battery string. You will have to work the numbers to find out the charge time, I would buy the 80 amp version. It will take a while to bring a string that size back up. Make sure you add a low voltage disconnect to protect the batteries. If they go flat, they will never come back to their original capacity. If you use a charge controller, and a 13.6 supply, the job will get done eventually. Note the charge curves. http://www.progressivedyn.com/prod_details/charge_wizard.html Best Converter seems to have good pricing on them. http://www.bestconverter.com/80-Amp-RV-ConverterCharger_p_173.html If you want really snaz it up, use a battery monitor gauge. http://www.xantrex.com/web/id/274/p/1/pt/5/product.asp You can use the alarm relay to trip your controller, to tell you when the battery capacity has gone below the set threshold. I have read, repeated discharges below 50% are not recommended for long life.

Re: [Repeater-Builder] Suggestions for Gel Cell Charging - Large Array
That was the general gist... The Charge controller will pass dc through from the charger or in this case the power supply to the load under normal operations, but be aware of the maximum current flow needed for the repeater as well as the batteries for charging.. a large stack of batteries has different charge rates and floats per battery... paralleling them makes for messy charging... Everything assumes each battery will charge/discharge at the same rate.. if the batts are matched this is true.. but 12v batts tend to be made up of several cells and those individual cells age differently in most batteries... assumptions will boil a cell and avalanche from thereOne larger battery is better than several smaller batteries... or put a separate charger on smaller groups... A big bank of say 8 90a/hr batts is going to take a lot of charge and that level could hurt the weakest cell in the lot under full bulk charge.. the deadest batt will take current first but 800 a/hr worth of batts will take a long time to recover if a discharge occurs...at 30 amps... sustained like 24hrs... if you double the charge current with a bigger charger.. you could be charging one battery at 60 amps.. and you should be real careful about that... Most serious battery stacks are series arrangements.. and higher voltage but flat current through the system... then run a UPS to get to 110v Many of Trace Engineering (Xantrex) and other makers of UPS type Inverters use 4 12v batts in series for 48v... the invert to 110v.. Series and higher voltage uses smaller wire gauges to accomplish backup... I would recommend talking to vendors before paralleling 10 batteries on a 12v charge controller...I would think some additional engineering would be suggested... Paralleling 200-300 amp batts is one thing.. paralleling 80-90 amp gel cells is another matter... especially 10 of them...

[Repeater-Builder] Arcom RC210 loading wav files
Has anyone had success loading wav files per the instructions in the Arcom RCP programmer manaul? The manual states to fabricate a stereo 1/8 plug using the tip to the speaker output of a pc sound card and the other end a 1k resistor in series to pin 5 of a DB9 pin connector. Then pin 9 to the ground of the 1/8 stereo plug. Then using the serial cable from the controller to the pc load the 16 bit mono wav file into the controller with the rcp programmer software into port . I have tried the above procedure and can barely hear the wav file when I unlock the controller and use 123 (wav file track number) command to play back the loaded wav file. I am using a Panisonic Tough book lap top pc. I removed the 1k resistor and tried the same proceedure as above and still can barely hear the wav file when I play it back. I have also tried the record volume pot at several positions including turning it all the way up. The play back audio is very very weak. The play volume pot has plenty of audio with the voice ID. I can also record and play back the dvr using a transmitted signal into the repeater. Anyone have any suggestions as to how to load wav files using rcp programmer? Thanks, Glenn WA7SPY
Re: [Repeater-Builder] Cable velocity
hi there -- Your making this all to hard -- if the coax is teflon then it is most likely .78 or .89 and if it isn't then it is .66. All of the velocity factors are in the ARRL antenna handbook. All you really need is information about the material in the coax and it will be easy to do. whether the center is foam, teflon, or plastic. take the velocity factor for it and built a 2 port harness. put 50 ohm resistors on the ports and measure the input SWR. If it is low, then measure the power into the harness and measure the power at one port. It shouldbe ~3db down. then your good to go. If it looks funny then meaure up and down a Meg and see if it gets any better. Assuming it does then your harness is long or short for the frequency you want to make it for. But most of the time you will be will within the necessary length if you get the correct factor. No matter who made it.

Yes, but unfortunately I've lost that info as I always use the FS-10; sorry. Bob NO6B Of course I'd find the info right after I sent that message. Unfortunately what I saved is a bit cryptic: To enter service mode w/MH-39: 3 9 vol. # normal mode: D3 My guess is that the above is entered in sequence while the radio is already on, as it'd be kind of hard to hold all those keys down while powering up the radio.

There is an RC210 list on Yahoogroups, as an FYI. You would be much better served by posting such questions over there. That being said, you need to first set the RECORD level as explained in the Hardware Manual. Once that is done, you will still need to find the proper settings of the sound card in your computer as explained in the RCP Manual. You did make the connection from your sound card to PORT THREE of the controller, yes?
