Apparently it's too harsh to tell people, PLEASE DO NOT TELL ME TO HAVE SOMEONE ELSE DO IT. Hi Jeff, Apparently you do not play the BatLabs Game very well? I'm sure you'll survive with the ever so perky bunch over here. I am looking for information on how exactly to re-tune a channel element for a MSR repeater. I've seen instructions as far as what to adjust on the element itself, but what I really need to know is; what equipment is required, how to hook that equipment up to the channel element, and what to look for while adjusting the channel element. The transmit channel element is best adjusted for frequency center by using a Communications Service Monitor setup to sample (off the on-air signal) read the main carrier channel/frequency. The simple way to set the IDC Control/Pot is to set the Transmit CTCSS (PL) Tone deviation to about 750Hz. In a stock MSR-2000 the repeat audio level is then set using the level pot on the Squelch Gate Module. If you don't have access to a Service Monitor, a decent Frequency Counter will at least let you net (adjust) the frequency to F-center (on the desired frequency). If you move the transmitter more than say... 500 kHz from its last alignment location, you should repeat the Service Manual Alignment steps on or near the new frequency. The Receiver is a different animal. Take the Receiver frequency and add and/or subtract the receiver IF frequency (most often 10.7 or 10.8 MHz for the VHF Receiver). The formula you use depends on your receivers IF Frequency and Injection Chain, which translates to which side of the IF the multiplied crystal frequency ends up on. In your example it's probably F-frequency minus the IF Frequency equals the multiplied Channel Element injection frequency, which is what you want to set/align. Put a X1 Scope/Text Probe on your Service Monitor (or Frequency Counter) Antenna (Low Level RF) Input and place it down onto/near the receiver circuit board. You can also use a decent quality frequency counter if you're more careful. At some location on or near the board you will be able to monitor and measure the output of the RX Channel Element Frequency, then set it for the expected Injection Frequency. As an example: A receive frequency of 151.625 MHz minus a 10.7 IF frequency equals 140.925 MHz. Sniff around the receiver board until you observe a signal in that area, then net (adjust) the channel element frequency to the expected 140.925 F-center location. If you can't find the expected frequency you might run the numbers for a 10.8 IF Frequency and sniff around 140.825 for the channel element injection frequency. In both the above examples, a X1 (times-1) Scope Probe or something similar is handy to use. If you can't get/find a signal, make a short antenna probe by clipping a small length of insulated regular wire onto the end of the probe. The end of the wire held by the Scope Probe jaws should obviously be stripped bare. Try not to allow the sampling wire and/or probe to directly contact/short any of the exposed metal parts on the receiver board. Now I realize that I need a new crystal as well, and I realize it can all be done professionally with temperature compensation. Yeah but in many cases professional is a lot more expensive than it really has to be. But what I want to know is how I can do it myself just to get started and make sure everything is going to work the way I want before I pay out big bucks to have it all done the right way. I have an extra set of channel elements, so playing around with one set isn't going to affect having the other set done professionally if I

[Repeater-Builder] Silver Plating - Cheap Easy
A couple of years back, in an exchange with an engineer from Texas Instrument Germany, who is working in Freising, Barvaria, I was told of a cheap and easy silver plating procedure he uses on his duplexers. He uses Photographic Developer (which has a really high level of 'free silver') and a simple one or two cell power source = 1.5 to 3.0 volts. (While not discussed, I would suggest that 'used fluid' may be better than new and may be obtained very cheaply). This should be an ideal solution for the DIYers in our group. If interested, why not contact Hans-Juergan Schott directly at h-scho...@ti.com ? This should be an interesting topic for our Tecnical Info page as well. Hans-Juergan, if you are monitoring, pls forward this procedure to us as I think many of us would be interested. Tnx. 73 to all, Cecil E (Gene) Ferguson. W4FWG

Re: [Repeater-Builder] Silver Plating - Cheap Easy
It's actually used photographic FIXER that contains a lot of free silver... the fixer removes any unexposed silver in the film emulsion. For many years I recovered the silver from my fixer by adding powdered zinc, which will dissolve more easily in the solution than silver will, causing the silver to precipitate out. Collected over 28 ounces over the years. His method of silver plating probably involved connecting the negative lead of a low-voltage source to the can, filling it with used fixer, and then suspending a zinc electrode in the solution, connected to the positive lead. The zinc goes into solution, and the silver, instead of precipitating out, plates out onto the can. If the fixer is sufficiently loaded with silver (exhausted, in photo-speak), it will plate out on copper without any current source, but adding the batteries will speed things up result in a thicker layer of silver.

Re: [Repeater-Builder] Recrystal MSR-2000 Channel Elements
Actually 462.600 is the frequency I'm currently running my Kenwood on. I would probably be putting the Motorola on the same frequency with a different PL at a different location. That would solve a lot of headaches if you're willing to part with them. I was thinking about doing ham later down the road if GMRS goes away, I'm sure you've all heard about the proposed rule changes. But until I hear that GMRS repeaters are not allowed (or must be narrow band) I'll be setting it up on GMRS. The Kenwood is more set up for a portable repeater for events right now. A group of us get together and help out with events when there aren't enough ham volunteers. Let me know what you want for the channel elements.
