Keith---

If you are looking for a turnkey rig like the Maggorie---be sure to look at the 
ACS (Advanced Communication Systems)  repeater lineup. Very good receivers with 
helical resonators and they come with a CAT-1000 controller and power supply 
built in. And, I think ACS will also sell receivers and transmitters seperate.

  Keith,

  Over the years I have been impressed with Maggorie as Ham vintage repeaters 
go.

  About money they do sell their receivers and transmitters not having to use 
their enclosures and power supplies. This can save some money. Might take a 
look at this.

[Paul Finch]

Group,

 

I have been working on converting a E F Johnson Fleetcom 530, got the
exciter done with .8 of a watt out of the exciter and have most of the
receiver tuned but am having problems with mixer.  Just no time right now to
finish it.  After I finish my new workshop I plan on getting back on it,
will have a lot more room.

Re: [Repeater-Builder] 222 Mhz

[res1q6fs]

I built my first ever repeater in 1979 using a split Midland 13-509. They are 
really easy to turn into a repeater. The TX puts out a good 10 watts and the 
receiver cannot be beat as far as sensitivity is concerned. My 220 repeater was 
on the air over 20 years as the Midland. It never ran more then 12 or so watts 
to the duplexer and the power at the antenna was maybe 3-4 watts. The antenna 
was a 6 dB crappie pole side mounted at 250 ft. on a 450 ft. tower. It hears as 
good or better than our 2 meter repeater which was at the same level on the 
other side of the tower. No one ever complained of the 220's anemic power level.

I picked up a 220 Maggiore fairly cheap a number of years ago and it performs 
about the same, albeit like others have said, the new Maggiore units are quite 
pricey.

The ExecII should be pretty close to the MII, I would think.

Don't spend good money on the made-for-ham boxes. First, they're more 
expensive then the RB conversions, and they WON'T work as well. 

I think I've heard of people converting Mitreks too, although like most, 
the PA's don't go.

I've seen two Mitreks transmitters that were converted.  In both cases they
started with radios that had blown up PA decks, stripped them and put
down 220 power modules.

One was a UHF and the conversion removed the last doubler from the
exciter and the following tuned circuits tweaked to compensate.
The dev pot was cranked up to compensate for the missing doubler.
The existing 440 receiver was used as a control receiver.  The 220
receiver was a converted Micor in a Spectra-Tac chassis.

The conversion of the high band transmitter was different - the 75mhz
to 150mhz doubler was converted into a tripler and the following tuned
circuits tweaked to compensate.
The receiver conversion was similar - triple instead of double in
the LO chain.  I have no idea what he did for a front end.

If anybody wants to do a 220 Mitrek conversion article I'll make room
for it on the Mitrek page.

I would recommend the Mitsubishi RA30H2127M and a 10dB pad.  Be sure

A lot of guys are just using old midland crystal radios if you can find 
them.

Those work better than hamtronics.

I second the Telewave endorsement, with one caveat... get the 6-can unit,
plus any brackets/hardware you need to mount it into a 19" rack, and if
you can swing it, and your repeater controller has analog inputs, get the
remote power/swr sensing option.  This option gives you two meter
outputs, one for forward power and one for reverse power.   You can get
the same thing from Bird - a rack panel with two line sections mounted
to it (a line section is what a Bird slug fits into, and gives the DC output
that is fed to a meter)

Re: [Repeater-Builder] 222 Mhz Duplexer Questions

[Eric Lemmon]

Chris,

If you're not running much more than 25 watts, the Telewave TPRD-2254 will work
just fine.  This is a four-cavity, bandpass/bandreject duplexer.  I have a 220
repeater in service with this duplexer, and it has no desense at all, even with
a preamp.  You need at least 78 dB isolation for 25 watts and 0.3 uV sensitivity
at 12 dB SINAD, and the TPRD-2254 offers at least 85 dB.  At 1.6 MHz separation,
going more than four 5" cavities only adds cost without improving performance.
Telewave, like several other duplexer suppliers, offers a substantial discount
for Amateur Radio buyers.  Go to www.telewave.com.

I have no financial arrangement with Telewave, just a satisfied customer for 15
years.

73, Eric Lemmon WB6FLY

If you need to buy new for some reason, I suggest that you take a look at
the offerings of Telewave in San Jose Calif.. They make a full line of
duplexers and they are very good and reasonably priced and they offer a ham
discount. So long as you are working with corporate money, I would suggest
that you spring for a 6 section unitit will cost you about 0.7 dB in the
receiver and transmitter paths which in practical terms is negligible and
you will be well away from any problems with desense.

  Duplexer Questions
  I'm in need of a new 222 MHz Duplexer for my company sponsored 
  club repeater. The guy that built and maintained our old box retired and 
  took his toy's with him so the club has to replace it with a new 
  one.As I have not been in the market for a duplexer myself for over 10 
  years or so, I'm not up to date on who still makes duplexers for 222 and 
  which are the better ones available. Are there any brands that should be 
  avoided, for technical or business reasons?I'd sure like to know 
  if there are any thoughts on which types e.g. Bandpass, Notch, Pass/Notch 
  or number of cans, etc.The new repeater will run about 25 Watts output 
  power and it will operate on a 1.6 MHz frequency offset. The RF 
  environment it will be installed in will not be near any other in-band or 
  adjacent-band transmitters that we know of.My thanks to the group for 
  your help in this matter.73 de Chris
