I use on of these on my repeater. I got some conversion info from an Engineer at Decibel back in 95. The drawing is not an offical engineering drawing and has a number mkt019/a on it you might see if you can get it. Cable measurements are cut lengths, connectors not included Open the cans and trim the helix to 7 1/4 turns. Pop rivet the cans back together on the low freq side... Can to Tee length 14 3/4 Shorted stub length 19 1/2 Interconnect (Qty 2) 29 1/2 On the high freq side... Can to Tee length 29 1/2 Open stub length 21 1/2 Interconnect (Qty 2) 41 3/4 For the arms of the Y cable at the antenna port 41 3/4 Qty 2 I used the long stub to make the short ones. I made new long stubs I did not change anything alse in the harness as it was darn close and it works for me. If you cant get the document from decibel I will send you a copy.

Hi Chris:
On Thu, 04 Mar 1999 19:34:36 -0800, csnichol wrote: I use on of these on my repeater. I got some conversion info from anOn one of the sheets that I have, there is a drawing number 040020 issue "G". I would have thought that the length of the cables would have to be modified, as the cans were on 45.140 / 46.190, and they will be going up almost 8 megs? Now I don't know if this drawing belongs to these exact cavities, so some differences may crop up. After your dimensions, I'll put in what is on my drawing: Open the cans and trim the helix to 7 1/4 turns.To get the cans in our band with the adjuster near mid range, I shorted 2 turns of the helix at the "open" end. This way, the cans can be returned to "stock". Is it better to just trim the copper? on the low freq side...same ("A" on my drawing) Shorted stub length 19 1/2This is strange. My drawing shows a value of 15" with a split up to 1 MHz, and no stub if 1 meg or higher? Interconnect (Qty 2)same On the high freq side...same Open stub length 21 1/2Mine shows 27" up to 1 meg, and no stub if 1 meg or more. Interconnect (Qty 2) 41 3/4same same I used the long stub to make the short ones.I would like the duplexor to work as best it can Chris, so do you think optimizing the dimensions for our band will yield any better response? If you cant get the document from decibel I will send you a copy.I think our drawing are very close. All the cables are lettered "A" to "E" in a chart and the chart has 3 rows, 400 to 600 Khz, 600 to 1000 Khz, and 1 meg or more (being the RX/TX separation). My cans are rated from 45 to 50 megs, so increasing the operating frequency by about 10%, should decrease the length of the cables by that amount...no? Do you have DB's web address? Thanks for all the help Chris.... Tedd Doda CET packet va3sed@va3sed e-mail lazer@... |

Repeater list server comments??
Kevin K. Custer W3KKC
Hi Gang,
A bunch of you that are subscribed here are also subscribed to the Repeater list at onelist. I am also subscribed to it and the GE list at qth.net. I received this attached email from the GE server. I thought the comments in this attachment from the co-moderator of that list were "interesting" to say the least. I am now not certain what the main interest and objective is on that list...?? Please be it known that this list is NOT biased for GE or Motorola or any other brand, and since this list is for repeater builders, repeater discussion IS the primary tone of interest here. The original email was received on March 04 1999, Today...... Kevin Custer, Repeater-Builder List Owner. |

IS NECESSARY. I REALLY DONT BELIEVE THIS BABY MONITOR OR CORDLESS THING. IF YOU WANT TO USE IT AS A RPT. DO THE NORMAL PASS CAVITY STUFF. BUT PREFERABILY GET A MASTER II LOW BAND AND BUY THE XTALS AND DO IT THAT WAY. IF YOU CAN LOCATE A BASE STATION THEY ARE CONTINUOUS DUTY. MY SIX METER RPT IS A LINKED VOTED SYSTEM WHERE THE RECEIVERS ARE LOCATED AWAY FROM THE XMITTER AND LINKED AND VOTED. ONE OF THE RECEIVERS IS A RANGER AND I HAVE NOT HAD ONE BIT OF TROUBLE WITH IT ON SIX. THE REASON WE ARE USING GE RADIOS INSTEAD OF MOTOROLA IS THAT GE HAS SEPERATE RCVRS AND XMITTERS ON THE XTAL RADIOS WHERE MOTO HAS THEM ALL ON ONE BOARD. LOOK AT THEM. YOU CAN PUT A GE VHF RCVR AND AUHF XMITTER TOGETHER AND HAVE A INSTANT LINK. ALSO THEY ARE BASIC RADIOS THAT ARE OF THE LAST AND BEST XTAL GENERATION. THEY ARE EXTREMELY TIGHT,SIMPLE, EASIALLY AVAILABLE AND OVER ALL VERY GOOD BE IT THE MVP THE EXEC II OR THE MASTER II . A FRIEND ONCE TOLD ME TO QUIT MESSING WITH MOTO WHICH YOU HAD TO CHANGE CAPS AND DO EXTENSIVE MODS ON TO GET INTO THE HAM BANDS AND USE GE INSTEAD. I FINALLY LOOKED AT THEM AND REALIZED THEY WERE THE BEST FOR HAM USE. I HAVE BEEN LOOKING AT ALL THIS TALK ON THE NET ABOUT GE VS MOTO AND REALIZE SOME OF THESE GUYS ARE WHERE I WAS 10-15 YEARS AGO. TRUST ME UNLESS THE MOTO IS ALREADY A REPEATER AND ON THE BAND YOU WANT YOU CANT BEAT THE GE STUFF. AND I DARE ANY ONE TO TELL ME THE DIFFERENCE BY LISTENING TO IT. ALSO YOUR GE UHF RANGER DOES NOT HAVE HELICALS THE RANGER SERIES HAD A TUNED FILTER THAT WAS NOT A HELICAL IT WAS SOME SORT OF FIXED XTAL FILTER. LOOK AT IT THERE ARE NO TUNING SLUGS.-- GOOD LUCK KEEP ME POSTED. CHUCK WD6APP--Original Message-----
