Re: GE radios
de Ric KK5RIC
Hi Bob,
Yes the ExcII will make a great ham radio repeater. I have not finished working up a written procedure for that unit as I am busy modifying the Master II's. If you can find a book for the radio, you can figure it out. If not, I do GE modifications on Master II and Exec II's. If you have more than one radio I will do a 2 for 1 deal if you want. I have added some details regarding this. de Ric KK5RIC At 03:23 26-02-99 -0000, you wrote: From: bshanks@...Most, if not all, descibe GE Mastr II. I have a GE Mastr Executive II. What is the difference? And, it is a UHF currently at 451.575. Will it operate within the Ham bands, or is the conversion too complex? Any help would be appreciated. Prices: GE Master II radios can be purchased from many sources, at this time I have a some VHF units with the UHS (pre-amp) receiver, I have some already pre-tuned on 146.62 Tx and 146.02 Rx and already modified for repeater operation with the internal controller. New crystals can be cut in 3 weeks or special ordered in 15 days at an extra cost. GE Master II VHF, or 6 Meter, unit above on any standard amateur repeater pair tuned and ready to install controller: $360.00 Controller with Voice $200.00 Controller for linking $250.00 For the same repeater set up, but with the radio's being furnished by you, GE Master II on any ham repeater band: Your GE Master II radio modified, crystaled and re-tuned on any amateur standard ARRL repeater pair tuned and ready to install built in controller: $150.00 Controller with Voice $200.00 Controller for linking $250.00 Your GE Master II or Exec II, radio modified, crystaled and re-tuned on any amateur standard ARRL repeater pair tuned and a DB-9 interface cable installed for external controller: $180.00 Many controllers available $150 to $2000.00 Many features available. The GE units are crystal controlled. This are repeater grade units with very clean transmitters and the receivers have helical front ends. They are 8 channel capable, so you could install more than one frequency pair, at about $60 each channel. Because of the quality these units are only good for about 1 to 1.5 MHz without re-tuning. The controller we normally use is designed for repeater with voice Id and messages or with CW ID and linking. To add phone patch and or linking requires a more expensive unit and the external DB-9 interface. These range from $150 to $2,000. Or use yours, I can set up radio with DB-9 connector and cable to connect to your controller. No additional charge to set up your controller with the repeater, but you will need to send the controller to me for that. If you do not send your controller, you will need to provide me the Make Model and details of RX input and TX output levels. I have this information on ACC, CAT-1000, NHRC-2/M2, Link Com units and a few others. Complete documentation provided of repeater modifications, and any interface to controller. Any controllers sold will have factory documentation provided as well. Controllers sold by us will be pre-programmed for your system, if desired. Repeater Band Information: 10 Meter repeaters normally will be set up as a slit site, about 1 mile apart. This will require a 10 Meter radio and a UHF radio for a link. The 10 Meter can be a GE Master II or a Exec II and the UHF can be either of those or an MVP. Duplexers are ava ilable from commercial vendors for 10 meter 100 Khz spacing but are very expensive. 6 Meter repeaters normally will be set up as a slit site, about 1/2 0mile apart or single site with duplexers. Split site will require a 6 Meter radio and a UHF radio for a link. The 6 Meter can be a GE Master II or a Exec II and the UHF can be either of those or an MVP. Duplexers are available from commercial vendors for 6 meter .5 or 1 MHz spacing but are very expensive. A group in Dallas builds some great 6 meter duplexers for a super price. 2 Meter repeaters normally will be single site and will use split antennas or duplexers. Duplexers are readily available for 600 Khz VHF repeaters both used and new. If you can consider UHF, you have many more options for portable emergency systems. But UHF GE radios are hard to find. If you have some UHF GE Master II or Master Exec II radios I will do a 2 for 1 exchange. You send me two working radios, and I send you a working repeater for your controller, or you can purchase a controller from us. UHF duplexers are very small compared to 2 meter 600 kHz duplexers. UHF used duplexers are available used and also new. Mobile duplexers are rated at 50 watts and many are found used at hamfests. With these mobile duplexers on UHF you can cover close to 1 MHz of repeater band without re-tuning the duplexers. At 25 Khz per channel that is 40 channels per MHz. The transmitter power adjustment is available in these GE units, but you must open the case and then remove the covers for the PA deck. Most of the GE units in the Master II and Exec II series are in the 50 to 110 watt versions. Unless the repeater is located in a building with air conditioning or extra fans added for cooling, I run the 100 watt units at 50 to 60 watts and the 65 watt units at 45 watts unless extra fans are added. In general I do not have any controls on these units. The controls are inside the unit or the unit control head I furnish and not accessible to the operator, except for through a small hole in the control head. An external speaker jack is accessible. I can build the units with the original GE control head, but you have to be careful because the operator can change the repeater levels and squelch settings. If you use the internal controller or some of the newer controllers that use discriminator audio, these can be utilized with a local control and not have any effect on the audio level. The squelch control will effect the repeaters operation. The units may be set up for CTCSS (PL, CG) tone operation. This will require a tone board from CES. I can send you some pictures, by E-mail attachment in JPEG format, of some of our recent repeaters built. Or a color brochure we have by mail. I also have some of my 50 watt UHF mobile repeater including duplexers with the built in controller, if you want. I built this for RACES/ARES use and originally had a controller with phone patch, linking, and four function relays for external control. I ran this unit for five years and never used any of those extra bells and whistles, so I replaced the controller with the current KISS one, but this one has voice messages that you can record by remote control, great for Emergency/Disaster needs. And it will also allow you to run it as a simplex repeater if needed as well. I also built a similar unit for 2 Meters for the Big Bend ARC in Alpine TX for mobile/portable use. We purchased Wacom 600 kHz duplexers for this unit and it was installed in a large Van type truck. It was used in Saragosa Tornado about 10 years ago. It is now installed in a large Pick Up truck metal box, weatherproof and has solar panels, batteries and portable 2m gain antenna installed and can be loaded into a 4 wheel drive and set up on a mountain top. This unit only has a KISS controller. I hope that this answers your questions. de Ric kk5ric 6 Cedar Crest Road HC 67 Box 157 Nogal NM 88341-9709 Do not ship anything to me without first makeing sure I will be here to receive shipment.

Unless you count the wall mount Mastr Exec II's. Essentially the same
hardware as Desk Top but in a nice little wall mounted enclosure. Combo number would start with a "W" as opposed to an "F". --Dave * REPLY SEPARATOR * On 2/26/99, at 8:49 AM, John Lloyd wrote: From: John Lloyd <lloyd@...>top models.station.

The UHF Exec II will tune to the 440- 450 ham band with no problem. Just put in the ham crystals and tune it up! The Exec II is a little different in how the modules connect together and how it is laid out. The Audio Squelch is completely different. They both work about the same. Modifications for Repeaters is very simple and straightforward. See the NHRC Webpage. John Lloyd, K7JL Utah VHF Society ------------------ bshanks@... wrote: From: bshanks@... |

I actually like the Exec II a bit better, but I won't reject a Mastr II. Go to my conversion site: You could say I specialize in the coversion of the Exec II desktop radios. You'll have no trouble getting the 451 down to 440. No RF mods needed. But you will need to do the alingnment. Not hard, but you'll need a sig gen for the RX tuning. Good luck with your project.

GE radios
I have found several mods for GE radios to convert them to repeaters. Most, if not all, descibe GE Mastr II. I have a GE Mastr Executive II. What is the difference? And, it is a UHF currently at 451.575. Will it operate within the Ham bands, or is the conversion too complex? Any help would be appreciated.

From: mtwilley@...found some Exectutive and from what I here they don't hold up as well as the Master ll radios. Anyone have any coments... ThanksThis should start an interesting debate. I've found the PA in Mastr (note: Mastr not Master) II Repeaters has a real weakness where the RF leaves the board. It's an easy fix if you get to it before the transistors fail, but it's a very frequent failure. I've only had one PS failure in an Exec II. No PA's yet. The Mastr II does seem to be built a bit heavier. And if you want a LOT of power, Mastr II is the only way to go. I don't think there's a 100 or 110 watt Exec II. And there's better support for Mastr II. There's even a drop in controller. The ICOM's in a Mastr II are totally shielded. But the Exec II can use any ICOM for any band. Nice when you're converting. I have some Mastr II repeaters, but my work horse is an Exec II. It's also my favorite to convert. See my conversion site: I'm sure there's some technical problems in the Exec II that were cleared up in the Mastr II. If by any chance you mean Mastr Exec Radios (not Mastr Exec II) avoid them. I have a couple. Real pain to work on. Not as modular as the others. I've run one for years for one week a year, full time, for a Ham Fest info channel. At least that PA is solid. If there's something specific you're thinking about, let us know. Ray, KD4BBM |

I have successfully converted two UHF and one VHF mitrek radios to repeater
service. 1) check out www.seits.org for info on cenversion 2) the radio's must be aligned propperly BEFORE beginning the mods. 3) the radio that is 'not xmitting' will probably come alive during the alignment process. good luck LOU<<< -----Original Message----- |
