The real FM exciter is only really useful if the 2C ICOM in use on the PM exciter will be plug play on the spare part. The ICOMs are different. Also, some people *need* that exciter for specialized applications, and would probably trade you quite a bit of MASTR II stuff for that one... if you're looking to do that.

[Repeater-Builder] GE Delta
Well I was over at the junk store looking for UHF commercial radios for the GMRS project and didn't find anything for that but did find the drawer unit for a low band GE Delta for $5.00. So now what. I would love to be able to slide this thing into 6m and use it for something. How does one go about programming one of these puppies? I have seen a lot of different things out on the net but nothing that seems to say the easy way to get it programmed. Will it slide into 6m by just programming it or does it need to be modded as well? I know another project but that is how these things happen.

I have a pretty good relationship with the two local shops here in town, one Macom and the other Motorola. They regularly call me to help clean out the garage.

Re: [Repeater-Builder] GE Delta
If the unit you are looking at is a programmable type, you can program with the RFGuys programmer by removing the chip and plugging it into their programmer board which plugs into the parallel port of your computer. You have to use DOS to generate the personality (a 256 byte binary file) to move to the chip. They supply a program to generate the personality. I use one of these programmers to generate personalities for GE Rangr and GE Phoenix radios. I don't have any programmable Deltas. Some folks have indicated problems getting their computer to work with this programmer, but I use an IBM 390 laptop and it works fine. Be aware that there were lots of crystal controlled Deltas made also. You will have to order crystals for those types. To verify that your radio is programmable you will find an XR2212 EEPROM near the microprocessor in a socket. This is the chip you remove and plug into the RFGuys programmer. RFGuys markets their unit on Ebay. 73 - Jim W5ZIT mung_bungholio [EMAIL PROTECTED] wrote: Well I was over at the junk store looking for UHF commercial radios for the GMRS project and didn't find anything for that but did find the drawer unit for a low band GE Delta for $5.00.

RE: [Repeater-Builder] Re: GMRS Radios
First of all I know we are not supposed to talk about part 97 rules on here but these are part 95 so that should be OK right J Anyway. I wonder if you are talking about store and forward being forbidden on FRS? That is true. Here is some reading material about store and forward on GMRS. A conventional base station can also be set up as a repeater by receiving a signal in the 462 MHz band, and then retransmitting that same signal after a slight delay on the same frequency. This requires attaching an inexpensive store-and- forward device to the base station, but also requires using another device to shut the station off if it is operated from a remote location. Source http://www.wirelessgalaxy.com/twradios/Material/What_is_GMRS.pdf OK I have looked and looked. Lots of people doing simplex repeaters or store and forward on GMRS http://frwebgate1.access.gpo.gov/cgi-bin/waisgate.cgi?WAISdocID=934430266220 +1+0+0 http://frwebgate1.access.gpo.gov/cgi-bin/waisgate.cgi?WAISdocID=93443026622 0+1+0+0WAISaction=retrieve WAISaction=retrieve Here is the part 95 rules and nothing in there about not doing it on GMRS.

Re: [Repeater-Builder] Mastr II white noise on transmit
Every time I had this problem it turned out to be discriminator noise somehow coupling into the CG HI input (assuming you have a duplexed radio).

So now what. I would love to be able to slide this thing into 6m and use it for something. How does one go about programming one of these puppies? I have seen a lot of different things out on the net but nothing that seems to say the easy way to get it programmed. Hello Vern, If you have the 2212 chip (as opposed to the xtal vers...) there are several ways to attack the programming issues... None of which is too EASY but not too difficult either...Simplest is to find a GE dealer in you area that might have the capabilities to do thatnext would be to purchase any of the programmers made for doing the XR2212 Chip. This chip was also used in the GE Phoenix Series of radios so any programmer for that line should also work...) There are several available, such as the one from RF GUYS,...There's also one available from the NHRC group,. and if you don't mind building your own, you might try the KG4LNE software and programmer, or the KA9FUR software and programmer. ( just Google those sites)..sorry don't have the links handy. There are also what's known as Downloading Type Control heads available which will download freq tone info to the radio every time it's turned on but they too require special (tough to find ) soft/hard-ware... Will it slide into 6m by just programming it or does it need to be modded as well? I've put 2 deltas on 6mtrsI may have gotten lucky, but both Moved just fine...No special mods required...They will however need to have the VCO's reset, as well as the Recv. Front-end cavities re-aligned. Also, I cut the power back to 45W for my piece of mind... One Caveat...Are you sure you have a high-end split The Deltas came in 3 ranges for the Low band model29-36, 36-42, 42-50, One way to tell is by the Combination number on the radio (if it's still attached)...If you have a high range version, the combo number should look something like...N3DD3N060TB...or N3DD3N110TB... The Key is the 3rd letter...in this case the D(42-50Mhz)...a low end vers.(29-36Mhz)would have a B in place of the D...a mid range (36-42Mhz) would have a C in the 3rd positionPower is indicated by the 060-60Watt 110-110Watt Try the KA9FUR web site for some interfacing ideas (without control head...also Buck's Packetradio.com web site...He has some information there about using the Deltas for Packet,..but this will Guide you towards a Non-Control Head set-up..
