I Have a few questions on repeater Antennas
Michael Lussier
I am looking for some help with antenna questions for my GE MASTRII/RANGR
Repeater What is the consensus on 4 bay dipole arrays for repeater antennas ? I have looked into the coverage maps with both the 4 bay dipole array and an Omni stick. The closest repeater on the same pair is 50 miles away. The idea of going to the array was to place a null in the direction of the other system. According to my coverage maps it cleans up and expands my coverage going to the Omni. Now for the second part of the question. The 4 bay array antenna have a phased harness can I put three of them at the same level and the fourth antenna as a reinforcement in the direction I want ?? Currently the 4 antennas on the array are on the western leg pointing North and South my coverage is for no better word Terrible 7 miles away to the east I get an S4 , to the west 20 miles an S9 /Mike From The Heart of Spotsylvania County, Va. 146.775 - / 203.5 442.850 + / 203.5 [[ MICHAE~1.VCF : 33 in winmail.dat ]] |

band, but I don't recall how. I probably had to edit the hex data. If you can't find anyone else who can do it, I'll research it more. It can be done. :) *** One word of warning: The oscillator becomes intermittent at low temperatures (<20-30). I don't recall how I got around that problem either, but I think it involved adding or removing a transistor. But when it works, it works very well. Joe, KR3P D.J.H. wrote:

Will do Ralph,have a friend in the mobile buiss.,he can do the vhf
versions but not the uhf. Doug Ve6zh ---------- From: Ralph Hogan <rhogan@...>uhf's I like to do. some! GE uhf Phoneix,anyone have info on reprogramming for the ham band?? |

Doug,
If you find out on the phoenix-S, let me know too. I've got a couple of uhf's I like to do. BTW Kevin, thanks for the heat shrink source. We will definitely get some! Tnx, Ralph WB4TUR Kevin,i was able to read all messages today.Back to the question on the GE uhf Phoneix,anyone have info on reprogramming for the ham band?? Doug VE6ZH |

oh well i got all the pins out for the back of the radio and they have great
rx in ther i use one for tx and one for Rx for a repeater they work great.....i can give u that and i am working on putting them into one rack mount at thins time use them for links also good rigs looking for more for uhf and vhf Tracy585@... wrote: From: Tracy585@...-- Brent DeSalvo (KF4TNP) 146.625- 442.100+ Lewisburg, Tennessee Do not forget to Confirm your visit!

Bill,
Tracy, K0DOE, here. I built a dual band remote using a Kenwood TW-4000A. Works great! I used the controller momentary outputs to 'strobe' (ground) the mic up/down switch for frequency change. The voice module installed in the radio outputs the frequency readback. Additional outputs from the controller could be used to adjust power, change to vfo, etc. Guess it depends on your controller what you will be able to do... Definitely helps to have frequency readback! I know of several remotes that have been built without it and they are always where their not supposed to be! 73 Tracy |

If you are able to net the crystal on frequency, you should be able to get MORE deviation from the exciter now that it is on 220. Why? The crystal oscillator has been multiplied more times (18 instead of 12.) 417 cycles of deviation at the oscillator is necessary to make 5 kc. deviation at the output on high band (2 meters) the same oscillator deviation (417 cycles) should net 7.5 kc. deviationon 222 mc. You should have more than enough deviation on 222. Sounds to me like there is a problem with the buffer amp (Q404) or firsttripler (Q405.) Do you have the schematic, and trouble shooting procedure? It shouldstill apply. Does each stage tune at a precise peak? How about the tuning slugs,are they all the way into the sleeve or way out? Did you put any caps on the channel element to net it on frequency? If you did you may have taken away the ability to deviate the oscillator. If you cannot get this transmitter to work, I can send you a TLD 5382Astyle exciter and channel element. Kevin >> Kevin and the Group.. I had a problem with the crystals, doing two conversions here for 222mhz, thats why i could not get the proper deviation.. I stopped by the local crystal manufacter here in jersey, and looks like for the conversion the crystal needs to be cut with different specs.. (out of band specs)..and not the regular cut..they cut the crystals with commercial specs and it did not work properly.. So i have to way another few days for them to get me new crystals.. On some micor KXN??? elements the ones that have the varactor inside the element, theres a cap in series with the varactor, and changing the cap has the affect of increasing or decreasing the modulation sensitivity of the element, thats were i thought my problem was with the deviation.. I did more then ten conversions on micors to the ham bands and only a few i had to change this cap.......on the comp. tunning cap yes all of them i believe i went as high as 45pf and even on some taking this cap out.. Will see when i get the channel elements back maybe i will get more then the 50mw out of the exciter.. Will let you all know when i get it going .. Fred |

<body> I am looking for anyone who has experience with the SR4D repeater controller. I am using one and I have been experiencing audio problems during the voice mail mode, and it also mutes the ID at times. I am currently using it on a 6 meter machine mitrex running split site.
