This is the one from Microsoft. They have cleaned up a lot of the problems that the earlier versions had. The new release is good for Windows 98 and above. We have not had a single problem with the new release. We are using it on 98 and 98SE, NT 4.0 SP4 and SP6, 2000, 2000 Pro and XP Pro.

Re: [Repeater-Builder] Mitrek
Hi Mike Thanks. Our frequencies are not same as US. We are confined to 434-438. So I cannot expect availability of crystals / channel elements in this range. Of course they may be useless in the US. The local manufacturer of crystals can supply me with whatever I need within 7 days and that too for a cost under $3 but I need to specify the parameters - that is less than what it will cost for mere postage from the US!!. I do not think any one in India has even seen a Mitrek. So it becomes important to be able to specify. Of course I can just blindly specify 3rd overtone crystal - series resonant and see what happens. Then I could alter parameters after I see what it does. Even if I have to waste a couple of crystals is no big deal compared to the hassle of ordering and getting the xtals from US. If I get hold of the manual including the schematics I can make a more intelligent guess looking on the channel element circuit diagram. There is a ham in Bangalore who used to work for Motorola and I hope he will be able to hunt out some information. I thought someone in the US has a clue!! Are there service manuals around - could one beg, borrow or steal one ? Thanks for your help. 73s Venkat VU2KV At 03:51 AM 19/12/2004, you wrote: I may be able to help, but it will take a day or two... While I make a couple of phone calls, Venkat what frequencies do you need? Maybe someone on this group has them in their box of elements left over from their amateur radio conversions. Of maybe someone has a leftover set of UHF commercial elements with good crystals that are near his frequency and can send them to Venkat. His supplier could take those crystals, plug them into a test circuit and determine the parameters by what loading is needed to pull the test crystals onto the indicated frequency.

I am getting a T44JJA390DK and would like to replace the crystals for local frequencies. I would like to get confirmation that the crystals are 3rd overtone crystals - series resonant - 32pf capacity - (freq =10.7 / 9 for RX) I do not know the freq multiplication for TX crystal. There is a local crystal manufacturer who can supply xrystals if the operating parameters are specified. Can anywho has a the service manual make me a copy ? Venkat VU2KV Yahoo!
