How can the Final in this produce FM of it's own, I would think cuz it's a

That transmitter is extremely microphonic. You are modulating the VCO

 Bob,

 While the number of folks submitting to sub-standard HDTV is common,
 those
 of us who know that none of the DBS and cable providers are sending true
 1080i still seek a good quality off-air antenna.  At this point in the
 game, it is the best way to get true high-def.  And a whole lot cheaper
 for better quality pictures than the highway robbery rates that most of us
 pay for crappy cable.

 Interesting that we all plunged headlong into technology, only to find
 that
 we have been sold out to multi-casting and bandwidth limitations of the
 cable and DBS systems.  How many home shopping channels is enough?
 Dish-net
 is sending around 15 of them...  yet I need a second dish to get PBS.
 What
 is wrong with this picture?

 I still long for the day when light-pipe is in every home.  America is so
 far behind the rest of the developed world with regard to data delivery,
 that it just isn't funny anymore.

 Many nations have multi-megabit access for less than 25% of your average
 baseline cable bill.  The devil is green!!  Just follow the money and the
 truth is evident.  Fiber is cheap these days..  so is your congressman..
 for sale to the highest bidding lobbyist.

 Even the radio community has jumped on the multi-casting bandwagon as

  CONSUMERS PREFER EXPANDED BAND MULTICAST CHANNEL DISPLAY

  In a study for Cox Radio, consumers were asked to consider
 two possible options for displaying multicast radio channels.
 Currently, and possibly for the next few years, HD Radios will
 display multicast channels with the parent station's frequency
 followed by the sub-channel number (e.g. 88.1 HD2  88.1 HD3).

  However, 90% of the consumers surveyed preferred the
 expanded band option of display where multicast channels appear
 as if they were being broadcast above 107.9 MHz.  For example,
 88.1 HD2 could be displayed as 108.1 MHz.  How these make-
 believe frequencies will be assigned, and by whom, remains to be
 seen, but the idea has strong consumer appeal.

 Most end-users have no idea what they are signing-up for...  Sad, but

 most consumers are stupid.  Capitalism is alive and well...  just look at

 Thanks,

 If they are UHF, then anyone who wants a full duplex
 420-440MHz point-to-point link will want them.
 
 The 700 and 1000 series radios can be range-changed
 to 406-440 in minutes.  The parts even plug in.
 
 Then you unbolt the transmitter PA deck subchassis (one
 RF tube plus it's transistorized inverter HV supply) and
 replace it with a coax jumper.  Some models used instant
 heat tubes (i.e. the tube heater was switched by the mic
 clip switch), others used normal tubes. But the tube
 amp can be removed as a complete subchassis.

  Guess again ... no tube / no transistorized inverter HV 
 supply either.  You must be thinking of the RCA Super-Carfone 
 and Series 500 mobiles. 

  Would you like to visit ... and dig through my collection 
 of RCA issued factory Instruction Manuals?  

  I used to service those radios way back when ... and do 
 remember which is what. 


 After all that work you end up with a radio that will do
 a nice clean 10w full duplex on a 420-440MHz link
 channel all day long (continuous duty) with no pain
 or strain

Re: [Repeater-Builder] Re: Old duplexer tuning question

2005-12-20 Thread Doug Bade

There are some extremely broadband linear amps you can find on Ebay 
and such that amplify up to 1w from dc to 1ghz with 30-40db gain 
which can be driven off the gen port of your monitor for extra 
dynamic range. Calibration obviously goes, but when you are trying to 
see the bottom of the range, an extra 30-40db can help you see the 
bottom , Be aware that a pad on the output of the amp which can 
handle its drive level is a must. 6db or so should be sufficient 
to maintain 50 ohm integrity.
IFR made a high level adapter for the 1200 which hooked onto the 
front of the box in the gen side of the loop for more signal range

I also use a portable with a 6db pad as a gen signal on low power 
when I need more headroom. None of this is equal to  a good network 
analyzer, but it gets pretty close

2005-12-20 Thread Jeff DePolo WN3A


If the PA microphonic AM'ming is severe enough, there could be enough power
supply modulation, due to the PA current varying by the AM occuring in the
PA, that FM at the same modulation rate can occur in preceding exciter
stages (such as in the crystal oscillator, modulator, active temperature
compensation circuits, etc.).  Not knowing how a T301 is designed I don't
know how likely this is, but it's quite possible.

Re: [Repeater-Builder] Re: Old duplexer tuning question

2005-12-20 Thread [EMAIL PROTECTED]

I'm assuming that if the old RG-8 cables are being replaced with RG-214 cables 
that are the same length, that the velocity factors of both types of cable are 
the same.

Subject: Re: [Repeater-Builder] Re: Old duplexer tuning question

New cables will be a lot more flexible, and with
RG214's double shield, they should work better too.
It's tempting to use the coax and TEE fitting as a
handle when picking the unit up - don't do that !

I found that the connectors added exactly 1/2 inch to
the cable length PER CONNECTOR, so you would want to
cut the coax 1 inch shorter than the final lengths of
11-1/2 and 12 inches. I solder the center pin, rather
than crimping it.

Not too many analyzers will be able to go down to the
100+ dB that these duplexers are capable of providing.
That's one reason why they tell you to tune each
section separately. I did find that if I use my signal
generator at a fixed frequency, rather than the
sweeping tracking generator, I can tune the spectrum
analyzer to the same frequency and crank down the
filters. I can barely see the sig gen around 120dB
down or more, on the final configuration.

As others have mentioned, if your equipment does not
provide a good 50 ohm impedance, you should use 6-12dB
pads on each line connected to the section you're
tuning. Of course, adding this attenuation pushes the
signal even further down into the noise, but it should
not be a problem on any single section. Use as much
signal from the tracking generator as possible (i.e.
+10dBm or more).

The resulting notch from the entire duplexer will
appear to be quite wide, even though the individual
section notches are quite narrow.

Good luck with it in the morning when it's warmer.

[Repeater-Builder] Re: RVS8 Voter Help needed.

2005-12-20 Thread ldgelectronics

Put a scope on the audio output of the voter and see if the tones are 
getting through.

If not, put the scope on the audio input of one of the receivers that 
you are testing and see if the tones are there.

If not, go back to the remote receiver and put a scope on the receiver 
to see if the tones are there.

If you have a controller on your remote receiver, make sure it's set 
to pass touch tones. Many controllers will mute touch tones (by 
default).

Dwayne Kincaid



 Ok, all seems to be working, I have five channels up and running, 
they all seem to vote well.  The only issue that I have now is that I 
cannot get the controller to accept any DTMF commands from any of the 
receivers.  The echolink controller will accept the commands just 
fine, which goes through the controller.  Any ideas?

Yep, 66%.  Unless it's RG-8 foam, but I'm 99% sure that PD used regular

Re: [Repeater-Builder] Re: Old duplexer tuning question

2005-12-20 Thread Bob M.

If the VF is different, then the lengths would need to
be recalculated. The factory cables use MIL-spec
RG-214 (double shielded, silver-coated), with crimp-on
male N connectors, and the lengths of the new cables I
got matched the lengths in the table of jumpers
RFSystems sent me. When I made my own to the lengths
specified below, the duplexer worked just as well as
with the factory cables. It's hard to argue with
success.

When you have over 100dB of isolation/rejection, you
want all the shielding you can get, so RG-214 is the
way to go (compared to RG-8).

While the number of folks submitting to sub-standard HDTV is common, those

Re: [Repeater-Builder] RCA 700 Series Radios Available


  Paul, I believe you are correct. 

  The RCA Super-Carfone was the model with the quick heating
 filaments 

  The RCA Super-Carfone 500 Series was more solid-state but 
 had the slower heating tube final. 

  The RCS Series 700, 1000 and ML1000 were all solid state. 

  ... or something like that ...

  If they are UHF, then anyone who wants a full duplex

  The 700 and 1000 series radios can be range-changed
  to 406-440 in minutes.  The parts even plug in.
 
  Then you unbolt the transmitter PA deck subchassis (one
  RF tube plus it's transistorized inverter HV supply) and
  replace it with a coax jumper.  Some models used instant
  heat tubes (i.e. the tube heater was switched by the mic

Jim,

The RCA 500 series radios were two strips sort of like the Mastr Pro, the
Pro had an additional strip in the middle for the power supply.  My second
repeater was a Pro, I took the mobile power supply out and modified a 100
watt A strip supply to run it.  I had to build a 12 and 10 volt supply.

The RCA 700 (3.5X12X12) is more like the Mocom 70 but more square and the
RCA 1000 (3.5X12X15) series is the same as the 700 but has a BIG heat sink
on the rear.  There was one more model that was similar to the 1000 but was
basically the same radio with a newer looking head.  Been a long time, bear
with me I think I am close to what they actually looked like.  Then we know
what happened to RCA after that, the GE days!

Re: [Repeater-Builder] RCA 700 Series Radios Available


  Nope ... 

  One basic cad plated chassis with a metal casting on the front. 

  The receiver front end, oscillator / multiplier chain and first 
 IF sections are in the front mounted metal casting mounted on the 
 chassis.  The second IF and audio/squelch board is mounted on the 
 bottom of the back half of the chassis  

  The top of the back half of the chassis has the Quiet Channel Board 
 (similar to Motorola Private Line) next to the exciter which are 
 mounted above Second IF / Audio squelch board ... 

  The transmitter multiplier chain is on a separate chassis mounted 
 circuit board just to the right of the exciter. 

  The last power multiplier and PA deck part of the transmitter is 
 on the rear, but separate, aluminum casting / heatsink. 

  The two metering jacks are mounted on a separate bracket just 
 above and to the right of the receiver front end. 

  The RCA Series 1000 and ML1000 are just a higher powered 
 transmitter version of the RCA Series 700.

  BTW, the ML on ML1000 ... stood for Meadow Lands PA - where the 
 RCA Office was then located. 

  Hope this helps,

[Repeater-Builder] RCA 500/700 Series Power Amp Module

2005-12-20 Thread Robin Midgett

On the subject of the RCA 500  700 series (since there seems to be a 
knowledge base among the group)...the later models of the 500 series 
used a RF amplifier module to drive the PA. It is a blue package, 
that, I'm told, replaced (partially) a former complicated and 
unreliable tripler section.
Did the 700 series use that same module? I'm looking for one for a 
friend..no luck yet. I have several 500 series mobile rigs on hand, 
but all that I've inspected thus far lack the blue gain block that I 
seek. I haven't opened any of the pile of 700 series rigs yet.

RE: [Repeater-Builder] RCA 500/700 Series Power Amp Module

2005-12-20 Thread Paul Finch

Robin,

As far as I can remember the 700 did not use any kind of module, it seems
the multiplier stage showed out the top on the left hand.  I think Neil has
worked on them since I did, I do have at least two 700 VHF base stations and
one 700 UHF repeater I would love to sell!  The VHF units would fall on 2
meter Ham frequencies and the UHF repeater is already on 444.850 TX and
449.875 MHz RX.

If shipping is involved you better have deep pockets, they be heavy!

Paul

Subject: [Repeater-Builder] RCA 500/700 Series Power Amp Module


On the subject of the RCA 500  700 series (since there seems to be a
knowledge base among the group)...the later models of the 500 series
used a RF amplifier module to drive the PA. It is a blue package,
that, I'm told, replaced (partially) a former complicated and
unreliable tripler section.
Did the 700 series use that same module? I'm looking for one for a
friend..no luck yet. I have several 500 series mobile rigs on hand,
but all that I've inspected thus far lack the blue gain block that I
seek. I haven't opened any of the pile of 700 series rigs yet.

Thanks,

HDTV stations use the same channels as analog TV stations.

If you have a channel 2, for example, and they put up a HDTV station, it
may be on TV channel 19.

You know, this subject (mail subject line) reminds me of the stories I
was told about them coming out with antennas for *COLOR* TV that were
interpreted to be different from BW TV antennas. Supposedly, for color
TV you needed a Color TV antenna.

BW TV, Color TV, HDTV... they ALL use the same frequencies and the same
antennas would work equally well.

---Back in the early 70's, I worked at an electronics store that also did
quite a bit with higher end consumer audio. 

I remember the fun we used to have convincing customers that should use the
bare copper conductor in their speaker wire for the positive connection and
the tinned conductor for the negative because one was better for positive
electrons and the other was better for negative ones.

We never did have anyone question us

There are always things like digital ready, I made sure that was on the
pair of headphones for my portable CD player.

Or those gold plated connectors on the PC motherboard where the bracket
AROUND the pins is gold colored...those go really fast.

The short answer is it isn't easy, atleast that was my experience.
  

Start at QRZ.com you will find links etc much to much to go into here. 
But then I hate working thru beaurocracy more than most YMMV.  I did it 
about a year ago, I am glad I did but wouldn't want to again but that is me.

This is a good one .. how is audio 'digital'   its not a 1 or a 0 ... its 
analog ... just another way to raise the price tag on the same old 
stuff .. 

ummm  I would just love to have my repeater 'digital ready' .. think I 
could sell the old radios with the new tag ?
