Thankx to all for the info. i did find a manual - i have it here now and the seller is selling me a box of rca manuals that cover mobiles from the 50's to the end of rca area and some of the post rca models. Jimbo, the transistor was open on the relay buffer board - my full report is above. i never ...

got a service call to the local cement plant in the mid 90's, their Locomotive remote control went out on them. i told my manager "nice joke". he said no joke, you and the lead tech are going there. we went to the train area which we had only visited a few times to wire 72v to 12v converte...

thankx for the links - a great read.

n8uhn

you would be correct on the rem con panel. i have alot of experience in tube and newer moto and ge as well as johnson so the rca should be easy? NOT! the unit was dead and the osc sections were not working. i traced the white wires with the little black numbers and all was well - the unmarked wires ...

Hi All, hate to ask here but looking for manuals for the rca uhf 500 series repeater. i need the schematic for the control panel as well as tune up for rx,tx and pa. info on the ctcss "panel's" would be nice too. if i understand correctly the rx and tx driver "strips" were close ...

Hello: The sport base model number you posted says its a 40 watt not a 25 watt so the sm50 40 watt model number would be M44DGC20AA . Satelite That is very interesting. all the sportbase info i have found online lists it as a 25 watt uhf radio with 2 freqs. my bird watt meter says it's putting out ...

The sportbase's model is: L44GUA20A2AA. I do have both a service monitor and a spectrum analyzer with tracking gen. both make it a little easier to tune ham duplexers as the vhf ham rptrs operate on a 600 khz split ;) i've been in two way and ham radio long enough to have rib's from moto, ge and joh...

Yes, The error code is error #21 - radio not supported. thankx for finding and posting the other ref you found. too bad it did not say how to edit the sm50 model bytes to add the sport base model number. another idea - could one blank the eeprom or board and re init it as an sm50? i suspected moto h...

n8uhn

perhaps I'm missing something. Yes re-read the batlab sm50 page on hex editing. You need to enable the RSS to reconise the Sportbase as a SM50!!!!!! Batlabs still does not describe where in the mdf this needs to be done nor does it list what bits are the model info. another thing is the freq info i...

ok, I thought so - but thought i'd ask the braintrust first.

Thankx,

hi all, i'm working on a maxtrac with a strange problem. it appears to be carrier squelch only. rss does not enable the tone squelch sections. the rss is ok but the radio seems to be csq only- didn't know big M made a csq only maxtrac. can i dump a codeplug image from a "pl" squelch radio ...

Wow, all the questions i asked answered in 1 post, thankx i did forget to ask about programming but you answered my question anyhoo. it sounds like the programmer has it's software in rom - the electronics would not be too hard to build, but the rom and micro computer/controller might be. also getti...

Hi all, I have a trackstar railroad radio (ex CN radio) that is haveing rcvr prob's. i have no idea who trackstar is but i have heard GE made them or took the company over? the rcve audio is garbled but the radio does xmit well. i am looking for a manual copy or schematic's - pdf or jpeg would be co...

Wow, what a shock. i haven't been active in this list for quite some time but do remember Monty and his wealth of info and help. he even helped me with rib and radio info. to echo the previous posts: he will be missed and i too hope his memory and knowledge he has shared with us will live on. 73 Mon...

A friend of mine has an ht600 with a bad final. the radio is barely moving the wattmeter needle. does anyone know of a cross ref or other part number that rf parts or another company can look up? the number on the transistor itself is not in any non oem's catalog. his email is radiodoctor2002@yahoo....

n8uhn

yeah, i do. maybe then i can put the rt and ra moto base stations to good use - or a few of the other rockbound radios i have laying around. Hello. Never said this was a new idea, or old idea, just a good idea. The unit uses a single chip to do all the synthesizer. Does anyone else think this is wor...

My vhf, single ch, T-power has a control head similer to the ones mentioned. it is more oval then the motran/motrac heads and the mic does plug into it. i also have a 4 ch scan adaptor for the motrac/motran radios and have seen the tone decoder with reeds in it before. cannot remember if it was sing...

yep, the ink jet and most laser printers are a huge pain to try to get them to print in dos.

i use a laser printer that has a dos mode or a dot matrix printer.

you could try to find out if rss will print to a file then open the file in windows.

Bill

i have a tek5f test set with no cables.

anyone have any pinouts or diagrams?

or can anyone ohm out thier cables - and hand draw a diagram?

even a pinout of the test set connector would be great.

not sure about vehicluar, but moto did make computers in the early 80's. they bought a company called "four phase systems" and sold both fps and moto branded comps under the name "motorola -information systems division". i would like to add a system 70 and 90 fps cpu's to my mini...

are the springs missing from the battery lock button and are the battery contacts good (not worn) on the ht-600?

Bill

n8uhn

In the early days of radio and tone squlech (ctcss). motorola and other radios used mechanical reeds for encode and decode. the decode reeds would continue to vibrate after the transmission ended leaving a squelch tail. to stop this the xmtr would send a 120 or 180 out of phase ctcss tone being the ...

i have yet to try clear led's - i would use green or yellow - use whatever color you want to.

i think the clear led's have different voltage and current requirements - be sure to compare the specs between the clear
and color led's.

don't forget that any color led can be in a clear housing.

Good idea! i cannot count the number of times my Amphenol Ratcheting crimp tool has saved an install job. mine has the ctl-3 dies in it - it will crimp .213 (bnc,tnc and mini uhf) as well as .429 (n,pl259 and rg-11 f's) connectors it even has the pin crimp section of the die - but i never use them (...

n8uhn

YES a tnc will go radio to radio! both radios must have a tnc on them. you do NOT need a node to go through. a standard tnc is a 1200 baud (bps) modem. newer 9600 baud labeled tnc's are a 9600 baud modem. you may want to check out hamfest's or swap meets etc as the 1200 baud tnc's are usually quite ...

yes Franko, moto rss does check the state of the two pins 8 and 9 - if it finds then not connected together - i gives an error. connect (short together) pins 8 and 9 at the computer end of the serial cable, the now shorted two pins goes to the rib's busy line. the ganz rib calls them "busy in&q...

i cannot find a schemitac on the polaris rib. the "busy" line i was refering to seperates all the simple rib's from the moto rib. most simple ribs only have two lines going to the radio, bus + and ground, most ht's and mobiles other then the radius "rj45" plug radios need more th...

Thats why this prob is really puzzleing me. the gentz rib and the moto rib are alike, all the lines are the same it does include the buss- busy and even the bias circuts. i even did the mod for serial port probs which involved changing two resistors on the computer port. is there a way to "loop...

No, it won't do eather - packet is the ax25 protocal and aprs is a different encodeing method. if i remember right that modem was used for many years in analog vhf/uhf paging transmitters (it's the one with the rotary selector switch on the front,right?). it uses the bell 202 standard up to 2400 bps...
