Re: [Repeater-Builder] IC-2200H Digtal Repeater?

I would like the D-Star system but, Hams here seem to avoid paying for that kind of money. So I would like to compensate and try something different. Has anyone ever attempted this? Did it work or has it worked well for you? Any information would be helpful. Aaron VA6AE For reference: http://www.icomamerica.com/products/amateur/2200h/ The D-Star is an open standard so it is hoped domestic hams would get the soldering irons out and design their own versions for the various manufacturers. The IC-2200H looks like it has the prior generation digital board with the same modem but not the D-Star software in it. You would have to upgrade the radio (read, sell the radio and get the newer model) to the new mobile D-Star dual-band radios just published in QST. It is not a so sorry situation. If you wanna play and burn out your new 2200, it is your money. I would think it would make more sense to buy some commercial grade gear that has the bandwidth for the digital signaling and the duty cycle for it. Use that for the digital repeater system. BTW, There has been little mention of the flexibility of the digital protocols on simplex repeaters and links as well as the full duplex repeaters. I hope your experimentation pans out. I miss the old days with the PC Clones where they would leave a copy of DEBUG in the BIOS or a back door in some of the software. We need more hooks in the new software so we can get back to the future. Pity there is little of that in the land of the rising sun. Adam Kb2jpd Yahoo!

In the US, remote repeater control can only be done from 222 up. Do 2m and you may get into a bit of trouble. Good luck. Adam Kb2jpd Yahoo!

Aproximently. You would get slightly better accuracy from doing the math from a Watt-Hour stand point.

Re: [Repeater-Builder] Is my math right
John: You are approximately correct. The Mfg. will have a spec load and a spec low voltage where the load cuts off. A greater load than this spec and you should obtain less A/H and less than this spec load, you will receive a greater A/H rating. The hard part is to find the Mfg specs.

[Repeater-Builder] midland 13-509 tx freq stability... cap change?
Working on my midland 220 box, with new international crystals. Crystals are standard delivery, not rushed, so they should be pretty stable. They always are in my other rigs... Question: Is it worth swapping out the fixed value cap that is paralleled across the ceramic trimmer on the transmit side? Mine seems to drift around a bit more than I like. I have to assume the stock cap is an NPO type. Schematic does not state capacitance of this cap. Anybody know what it is? RF Parts sells NPO's, but is it worth it? Better ideas, if any? tnx and 73, Dave NA6DF Yahoo!

RE: [Repeater-Builder] midland 13-509 tx freq stability... cap change?
Dave, Keep in mind that the Midland 13-509 was built for the Amateur Radio market, and the transmit crystals are only specified to maintain .001%, which is 10 PPM. There is no temperature compensation in the crystal circuit, and you may make the drift worse by using an NPO capacitor. If you have the time and the test equipment to do it, you can determine a crude temperature compensation by finding out how much the TX crystal drifts for a given change in temperature, then using a capacitor whose TC has an equal but opposite effect. This capacitor will definitely not be an NPO type, which is stable over a wide temperature range. In fact, you want an unstable capacitor that exactly balances the crystal drift. Commercial radios of the same vintage often used bare crystals with a color dot on the side of the can, and you were instructed to install the appropriate color TC capacitor with that particular crystal. Not perfect, but adequate. You might also consider replacing the bare TX crystal oscillator with a small TCXO unit from any of several sources, including ICM. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of na6df Sent: Monday, May 22, 2006 10:48 AM To: Repeater-Builder@yahoogroups.com Subject: [Norton AntiSpam] [Repeater-Builder] midland 13-509 tx freq stability... cap change?

Yeah, makes sense.

Awfully nice to meet everyone! Maybe next year too? Who knows... Also got to ride up to Dayton with Dave K9DC from Indianapolis, and got to see what it's like to live 1.5 miles from your repeater site. Heh...
