...there are most definitely legal fm channels on 26 meg (can you guess what they are?) most motorolas cut off pretty much cut off just where they say they do- 29.6 mhz ....they did make 25 and up radios...not very common though.....lot's 'o cap changes......

richyradio

uhhhh.... flashbacks....tremors....sickly feeling coming over me.....modax 100/500's......weekend service calls.....frustration....telco interfaces...good thing they were all installed in hospitals so when I had a nervous breakdown I would not have to go far......

basically, a paging terminal ...

richyradio

...I'm laughing...I KNEW sooner or later I would get that reply! as for me, yeah, I think I would go with Zetron, etc...actually for my stuff, I build my own controllers- I let the radio do the pl/dpl encode / decode, but I build the cor, tail, timeout, audio gating...(and using external touch tone ...

richyradio

if we are talking about the supplys that ran maxars, etc they are not that bad- also used in consolette base stations...they made various models that went as high as 27 amps...(that one was for the motorola micom series) greeenish colored heat sink, 2 pass transistors on it....on the higher current ...

richyradio

let's see if I can reply today....having issues replying both at wotk and home (I hate when you write a long response and it gets trashed!) this panel has no '232 input....you just hook a pots phone to the rear just for the use of the touch tone pad....again, the decoder is accepting tones ...

hey what up w/ site....every time I try to post/ reply i keep getting the log in page???????

let's se if this goes through...

richyradio

O.K, anybody out there w/ intimate experience with the CSI model 154 rptr controller? here's what's up....a friend of mine has one of these in service, but it won't take touch tone commands via radio (rear panel phone ok) well, I tell him, make sure level, twist and cos is right, blah, blah blah ...

...really nice people...it's really amazing when people are sooooo polite!

...Hey, that's ok, we all like what we like...me, I have the habit of living in the past a little bit...(thank god I can still pass for being in my 30's....) I remember lusting over motracs in the late 60's, early 70's , I was a kid then, we used to ride our mini-bikes (lawn mower engine, crude ...

richyradio

.....I just can't see toting such a big radio around...sorta like carring a Bendix King radio....I guess I still like to keep low-key....I vividly remember people whispering "narc" behind me if I carried an ht-220 slimline or MX 320 around...(back when they were the "in" thing..and those radios were ...

richyradio

...I still cannot understand why you all need such an ugly geeky huge radio to carry around.....

richyradio

Hi...I was wondering about the sitemaster....some people don't like them, but I wonder if they have any reference standard as to what is better or worse...they all seem to be the two-way radio types, with no experience w/ much better gear, so I cannot trust their opinion as to what they think is ...

richyradio

to hell w/ all the geeky radio banter....I could care less about Nick or these radios that you all seem to get a woodie over.... what I really want to know................................sta-con, what is the "source" of that pic (avatar)..... that cracks me up, no many how many times I see it....was ...

richyradio

....problem is you don't have your Cowthief decoder ring yet- I believe you can get one in specially marked packages of Cocoa Puffs....

richyradio

'whaddya think they would do if we sent one in for replacement ? (besides laughing at us...) think RCA was the reason for that lifetime crap...they did that warranty thing first...they all knew those 80 billion ceramic tombstones stuffed under a can was a disaster...funny, motracs had much fewer ...

richyradio

....the later mocom 70's did away w/ the varactor tripler and went towards a micor- like pa....think the older ones were actually more reliable, though....(ah the days....tuning the tripler, and hearing it hissing at you, literally.....just like the Mark 12 IMTS phones...) I'd go mitrek, if only for ...

richyradio

....not long ago, I set somebody up w/ a bunch of gp-300's...I 'kinda like them, relatively simple, reliable...(well' here's the point) they all worked great for about one month , then, amazing to me, they all rapidly failed at the exact same time- they all lost either rcv or xmit audio, or both ...

richyradio

Hi there....hope everybody had an ok holiday, , as for me. I can't wait for Jan 2nd....thats my holiday! i.e. life back to normal.....as for programming the "reedless' pl deck, it's the same as the mitrek reedless deck, which I thought was documented here, but I can't seem to find it ...maybe i ...

richyradio

....couple of thoughts: I'm assuming you need a different pl on tx than rx? (why else would you go through the trouble of adding an external 'deck when it's so easy to re-program the factory deck w/ a few resistors...) granted maxars are 'kinda old and crusty, not the best in a mobile environment ...

richyradio

I forget weather it was the loops or the probes, (whichever one was the flat paddles that actually touched the can) but the surface area was so large, that as you tightened the knurled nut, the reject would jump around... sticking a little star washer (no split washer!) under there would limit the ...

richyradio

gee, am I not the only one out there with alot of heavy metal/plumbing with the names Farinon, Microwave Associates, Terracom, and all the other names which they turned in to as we progressed into the future? (i.e. microwave associates = Ma/Com, Farinon = Harris) (my personal favorite: Terracom- the ...

richyradio

if they still allow dc on the line, (which I find rather amazing) rig it up just like the big M used to do it- you'll need a transformer with "split windings" on them- basically, each side that connects to the phone line is not a single 600 ohm coil, but (2) 300 ohm coils.....if you can visualize ...

richyradio

the reason motorola gave that option originally had nothing to do with other types of radios, etc. but the fact that in certain situations, to get rid of certain receiver interference problems (via image response) (which is not much of a problem now 'cause they finally got the bright idea that if ...

richyradio

...you're asking for trouble with using anything higher than a 30 watt mitrek...when you start paralleling outputs with those wilkinson (pc board) couplers things start getting inefficient and really can't stand true 100% duty cycle...( 30 watt mitrek single output) turning the power down does not ...

richyradio

...You can' t use the reed type board for simultaneous encoding- decoding- however, the reedless type does a most excellent job of doing it- I use them all the time w/ mitrek repeaters...not only that, but you can use that IC that they use in their "gyrator" circuit ( the 8 pin dual op-amp near the ...

richyradio

...time for my Monday night posts...notice I only post on Mondays as I have to do xmtr/tower/antenna switching on Monday overnights (when work is done) at a rather large building situated in midtown manhattan that houses all the radio and tv stations...so this topic is pretty much up my alley...went ...

richyradio

I have never seen a Micom that runs on 24 volts and I sincerely doubt they ever made a 24 volt model...I own (at least) 1 of every model of micom that ever graced this planet, (I collect alot of wierd motorola s**t) and they are all 12v...did you not a while ago post about not being able to program ...

richyradio

I tell 'ya, as far as I am concerned, although I think when it comes to a simple, bulletproof radio for lowband, nothing will top a mitrek ( the less there is, the less there is to go wrong)...I remember when motracs came out (p.s. I have a full head of hair and can easily pass for someone in their ...

richyradio

....serrasoids were only used at low band, I believe, due to the fact that at low band, you don't have the luxury of having your modulated L.O. being multiplied that many times (and hence your modulation)....

richyradio

...I liked the older IFR's 1100 thru 1500's, but the COM- 120 B as far as I am concerned is an ergonomic disaster....I use the one at work to demodulate 88-108 mhz...( no wonder I found it stuffed away in the stockroom)

richyradio

....and they ALL have their permakay if filters go bad after time- especially the high band ones....ah, memories.......

richyradio

...I guess it all depends what you want to use it for....most 492's go to 21 ghz, whereas the 2712 tops out at 1.8 gig...it seems to me the 2712 was the replacement for the Tek "7L" series as it has some features specifically designed for radio and ntsc television transmitters- (demodulated outputs ...

richyradio

Hi John, was busy @ Empire doing finishing touches on our new "tower of power" for my employer, so did'nt get back to you sooner...basically, both the "receiver" and "transmitter" are identical radios-2 MX 300 walkie talkies stuffed under tin cans-the receive element is the "main" frequency ...

richyradio

ok, looked at the one I have, box says it's for gp 300... it's a 2.5mm plug, not a 3.5, "mono", and has more threads as compared to the pic Nand has above...no numbers on anything...for you, John, does'nt matter as you need an sma adapter, I'm sure Pasternack has them....not their greatest fan, but ...

richyradio

Hi John...the adapter you need, if it is for a visar, is not the same as the adapter for gp's ht's etc...the visar antenna is basically an "sma" connector....
you can get readily available "female sma to female bnc" adapters which work out real good 'cause they are not big and bulky...I think people ...

richyradio

Hi John, to sum it all up, you have 2 choices: (1) leave the radio as is, and get a 16.4 mhz offset (2) do not use the rx unit as the reference for the tx unit, get both a "channel" element and an offset element for the transmitter (this requires getting rid of whatever rf cabling is going between ...

richyradio

Hi! I noticed you put "Maywood" at the end of your post...if ICM can do the offset element, you can leave everything as is .... (I know the people at ICM, been there, very nice people from the midwest, unlike I the cynical dickhead that I am 8) I work in the city, drive down RT4/208 but...I stop at ...

I keep on loosing my train of thought when this happens....to make a long story short, I think I may be able to ...

richyradio

Hi John, I'm going to type this in bits 'cause if I take more than 5 mins or so the thing times out and my posting goes away!! this drives me absolutely insane sometimes!!!!! I looked at the ass'y I have, it is only a 4 ch version, and each board has it's own set of elements...what they did in yours ...

richyradio

bernie pretty much summed it up....even those 4 cavity reject only's easily do 100 khz...how else would those good 'ol IMTS phones work...(well, their rx sens. was pretty abysmal

)

I've achieved some rather amazing bandwidths w/ 6 cavity pass/rejects
(with negligible insertion loss)

richyradio

Hi...let me look at the assembly that I have to make sure we're on the same page- I'm going under the assumption the tx and rx units do not share anything in common, i.e. the elements in the rx unit being fed to the tx- and even if they are, that could be simply undone...(one would think they would ...

richyradio

Hmmm...from what I remember, as stated above, it's just two MX's stuffed under metal housings w/ feedthru's....the rx unit should have no tx modules in it (no offset, either) the tx one would have a 21.4 meg offset,so you would simply order your channel element for your desired tx frequency...if by ...

richyradio

Visars are strange radios...I have a few of them, luckily they don't get much abuse so they do not suffer common complaints I read about- other than the one problem which drove me absolutely nuts- and other models of big M port's do it too...THE FRIGGIN THING CRACKLES ON TRANSMIT!!! (to the person ...

1) all astrons suck

2) they are called pass transistors, calling them anything else shows you're "wet behind the ears"

I used to work on those things....generally, they were pieces of junk, super expensive for the owner...those pop rivet duplexers always got noisy, the chargers blew up alot, they were like homing pidgeons that always wanted to be in the shop...It used to be fun sitting at the other end in the ...
