Some of the comments on the Old Motorola's brought back a lot of Memories , There use to be a Store in oak park Il name Spectronics , I recall going there over 40 Yrs ago it was a Drive for Me too from Indiana , They had a large Disc Meter in the Window on 146.520 you could key your radio and check the Freq , I had a old Mot I think 80 D Tube Receiver on the Ind State Police 42.42 I needed a Xtal trimmer Cap for it and They had one for 25 Cents , The guy ask for My Ham lic . I did not have one and He said he could not sell me the part , I finally convinced Him it was a receiver and I had drove a long way So He sold it to Me , I saw pictures on the Wall of Old Motorola's Radios that were sent to the Dump , I never did find that place , I did some Dumpster diving at Motorola in Schaumburg a couple of times on the way back from a hamfest on a Sunday . They also had some Fancy Motorola HT-220 Scan Etc.

Re: [Repeater-Builder] Re: Digest Number 7357
Albert, 94 refers to 146.940 Mhz, the original frequency used by many on FM...I got on in 1968. Then if 94 was busy some would switch to 76 146.760. 94 was often referred to as Channel A Most new repeaters in those days were on 146.940 with the input on 146.340. 73 John VE3AMZ - Original Message - From: hitekgearhead hitekgearh...@hotmail.com To: Repeater-Builder@yahoogroups.com Sent: Wednesday, July 28, 2010 9:51 AM Subject: [Repeater-Builder] Re: Digest Number 7357 You guys will have to find a picture of that.

[Repeater-Builder] Interesting RSS occurence
I had an interesting occurrence the other night while programing one of my UHF P200's It is a radio I use for 70cm and is a 438-470 unit. Usually at the top right of the display when running the software, the bandsplit is displayed. Well, I noticed last night that it did not display 438-470, but it displayed 430-470. I could easily enter frequencies down to 430 without the need to do the hex editing tricks. I just thought this was interesting and never noticed it before. I am going to check my other UHF P200 and see if they display the same bandsplit. I wonder if it is the radio or the software that was modified or otherwise hacked somewhere along the way. Anyone else ever run into anything like this? Albert

Re: [Repeater-Builder] Re: Digest Number 7357
At 06:51 AM 07/28/10, you wrote: You guys will have to find a picture of that. It sounds hysterical! It was. It looked like a stock mobile microphone off a Motrac. He had a belt clip that normally held a HT, but the hangup button from the mic fit into it just fine. He'd have the end of mic cord stuck in his pocket. Some one would call him on the HT radio, and he'd answer on the mobile mic, and people thought he had a transmitter in his pocket. But if he pulled on the mic just right the cord would pop out of his pocket - and it still worked! I assume Mr. McKay built the transmitter right into the mic, no? Yes. Dick McKay K6VGP is an old-time 2m pioneer in the Los Angeles area - and despite being a career pilot with United (now retired) he's an exceptionally good engineer (a future project of his is a complete rebuild of a Beech Staggerwing). In the late 1960s when I first met Dick he had a 2m repeater that grew to six receive sites and two transmit sites, and a 440 repeater that functioned as a control channel and as an intercom among the dozen or so control operators. The two channels could be tied together or run separately. The system also had a HF remote base that could be accessed from either side, and normally lived on 20 meters. He can tell you stories about the Old Farts on 20 meters trying to describe the problem his SSB radio had with the strange sounding audio and the funny sound at the end of his transmissions... (the squelch tail) You've got a funny oscillation in your microphone was one such comment... At one point you could move around the band with the DC motor worm drive on the VFO knob. A quick tap on star or pound would bump you around 200hz. For may LA area hams that started out on 2m that system was their first exposure to DXing - occasionally you'd hear DIck working DX (like Pitcarin Island) while he sitting in a restaurant and talking on a handheld. The mobile mic transmitter was basically a modulated oscillator / quintupler that used a 29.38 MHz rock, and was powered by a 9v battery. The shield of the microphone curly-cord was the antenna. It probably ran 25-50 milliwatts. At SAROC he was receiving on an HT100 that he had modified from 2 channels to 6 (the HT100 was a real Moto product that was made from slimiline HT220 less the final transistor, and in a very short case that had the battery mounted behind the radio. In stock configuration the HT100 ran about 250-300 mW and was intended for low power applications like a stage crew radio. Due to the price it was not a popular radio, I've only seen one other than the one that Dick has. Some photos of Dick's radio are at http://www.repeater-builder.com/wa6ilq/ht100 Yes, the antenna on HT200s, HT220s, MT500s and HT100s collapsed into the case. He still has the HT100, and if he has the trick microphone, it probably still works. One toy of his that I saw only at SAROC was the hip flask he built from an intrinsically safe HT200 case (complete with collapsed Dixie cups stashed in the battery compartment). It looked like a stock radio until he popped the top cap off of the antenna and poured out the beverage. And you will have to excuse me, but what is a 94? Today you'd describe a repeater that received on 146.22 and transmitted on 146.82 as being on 146.82 and down 600. In the early days of 2M FM you'd say it was on 22-82 since the only frequencies available to repeaters was the range of 146-148. A repeater that was on 147.18 would be said to be on 78-18. The terminology started to get unwieldy when the splinter channels were developed (like 146.625 / 025) and when repeaters were allowed in the 145 area, That's when the current terminology became popular. So someone operating on 94 was on 146.94 simplex. I myself don't have stories like this because I am a child of the 80's, but I love hearing about it and am know amongst my friends as the keeper of old things. This is why you all keep getting questions from me regarding the Genesis radios.

Re: [Repeater-Builder] Re: 420Mhz Radio for Voter?
Look at W6KGBs article on moving 450-470 Mastr IIs to 420-450. It's on the GE Mastr II page at repeater-builder. You could use a Mastr II UHF mobile with the receiver, exciter and IPA converted to 420, then use the receiver in an aux receiver chassis at the voter site. You wouldn't need to convert the PA, the IPA (driver) and a beam would be enough for a point-to-point link. Bob Meister WA1MIK did an article on converting the multiplier chains so that the UHF Micor receivers could hear down as low as 435 MHz (where the front ends run out of tuning range).

Re: [Repeater-Builder] showing our age (old HT's)
GE PR36, shudder! A brick with wires that easily broke when the case was opened or shut. Not a nice radio to have on the bench. I ran a Portamobile 1 on 52.525 about 10 years ago, guess I'll have to dig it out of the storage and see what shape it's in these days. Moving slightly off topic, I recently came across a Motorola mobile mic with the cast metal housing. A real favorite of the cops back in the day; it had many uses, only one of which had anything to do with communicating via voice. Other uses had to do with communicating, but were more non-verbal in nature and directed at the jerk in the back seat of the cruiser.

Wrap 2 starts at the bottom the the 1st wrap go upward to the connector. Apply another coat of clear spray to seal the tape. Layer 3 starts at the connector again and goes downward past the end of previous wraps. Spray again. This gives a good water tight job. When you are inspecting the antenna you simply note the direction of the tape if it should come lose. You'll know how immediately it may or may not need attention. I did this after pealing off the sticky mess of coax seal on a rooftop installation. The previous installer was even so thoughtful as to plug the hole in the base of the Stationmaster. Actually the only thing holding the connector to the hardline was the seal as I suspected by the noise when the wind picked up.

It sounds hysterical! It was. It looked like a stock mobile microphone off a Motrac. He had a belt clip that normally held a HT, but the hangup button from the mic fit into it just fine. He'd have the end of mic cord stuck in his pocket. Some one would call him on the HT radio, and he'd answer on the mobile mic, and people thought he had a transmitter in his pocket. But if he pulled on the mic just right the cord would pop out of his pocket - and it still worked! I assume Mr. McKay built the transmitter right into the mic, no? Yes. Dick McKay K6VGP is an old-time 2m pioneer in the Los Angeles area - and despite being a career pilot with United (now retired) he's an exceptionally good engineer (a future project of his is a complete rebuild of a Beech Staggerwing). In the late 1960s when I first met Dick he had a 2m repeater that grew to six receive sites and two transmit sites, and a 440 repeater that functioned as a control channel and as an intercom among the dozen or so control operators. The two channels could be tied together or run separately. The system also had a HF remote base that could be accessed from either side, and normally lived on 20 meters. He can tell you stories about the Old Farts on 20 meters trying to describe the problem his SSB radio had with the strange sounding audio and the funny sound at the end of his transmissions... (the squelch tail) You've got a funny oscillation in your microphone was one such comment... At one point you could move around the band with the DC motor worm drive on the VFO knob. A quick tap on star or pound would bump you around 200hz. For may LA area hams that started out on 2m that system was their first exposure to DXing - occasionally you'd hear DIck working DX (like Pitcarin Island) while he sitting in a restaurant and talking on a handheld. The mobile mic transmitter was basically a modulated oscillator / quintupler that used a 29.38 MHz rock, and was powered by a 9v battery. The shield of the microphone curly-cord was the antenna. It probably ran 25-50 milliwatts. At SAROC he was receiving on an HT100 that he had modified from 2 channels to 6 (the HT100 was a real Moto product that was made from slimiline HT220 less the final transistor, and in a very short case that had the battery mounted behind the radio. In stock configuration the HT100 ran about 250-300 mW and was intended for low power applications like a stage crew radio. Due to the price it was not a popular radio, I've only seen one other than the one that Dick has. Some photos of Dick's radio are at http://www.repeater-builder.com/wa6ilq/ht100http://www.repeater-builder.com/wa6ilq/ht100 Yes, the antenna on HT200s, HT220s, MT500s and HT100s collapsed into the case. He still has the HT100, and if he has the trick microphone, it probably still works. One toy of his that I saw only at SAROC was the hip flask he built from an intrinsically safe HT200 case (complete with collapsed Dixie cups stashed in the battery compartment). It looked like a stock radio until he popped the top cap off of the antenna and poured out the beverage. And you will have to excuse me, but what is a 94? Today you'd describe a repeater that received on 146.22 and transmitted on 146.82 as being on 146.82 and down 600. In the early days of 2M FM you'd say it was on 22-82 since the only frequencies available to repeaters was the range of 146-148. A repeater that was on 147.18 would be said to be on 78-18. The terminology started to get unwieldy when the splinter channels were developed (like 146.625 / 025) and when repeaters were allowed in the 145 area, That's when the current terminology became popular. So someone operating on 94 was on 146.94 simplex. I myself don't have stories like this because I am a child of the 80's, but I love hearing about it and am know amongst my friends as the keeper of old things. This is why you all keep getting questions from me regarding the Genesis radios. Keep the stories and good advice coming. -Albert --- In mailto:Repeater-Builder%40yahoogroups.comRepeater-Builder@yahoogroups.com, tony dinkel tonydinke...@... wrote: I remember that too Ken!

Re: [Repeater-Builder] Re: 420Mhz Radio for Voter?
I am using the Motorola CDM series of radios for 420-425 MHz links from voting sites. They make a low-split UHF split that covers 403-470 MHz out of the box, no mods needed. On the transmit sites, you will want to use a fan for cooling. We mount the RX radio and a UHF TX radio on a 1U rack shelf, use a 4 hole saw and drill a hole under the UHF TX radio, and purchase a nice Dayton 24vdc fan that is actually a ball bearing fan that you can count on for years of use, and let it go. Have not had any problems to date with these rigs over a 4 year span. at W6KGBs article on moving 450-470 Mastr IIs to 420-450. It's on the GE Mastr II page at repeater-builder. You could use a Mastr II UHF mobile with the receiver, exciter and IPA converted to 420, then use the receiver in an aux receiver chassis at the voter site. You wouldn't need to convert the PA, the IPA (driver) and a beam would be enough for a point-to-point link. Bob Meister WA1MIK did an article on converting the multiplier chains so that the UHF Micor receivers could hear down as low as 435 MHz (where the front ends run out of tuning range). Mike WA6ILQ At 05:10 PM 07/27/10, you wrote: Thanks Jeff, I'll keep looking around for those low split UHF Micor receivers. What about the transmit side? Maybe I should look for a unified chassis low split UHF repeater. Swap out the UHF receiver for a VHF high band receiver and use that for my remote receiver site. Then use the low split UHF receiver on the other end of the link.

Well, Spantek comes to mind as a dealer. CW Wolfe used to get a lot of stuff out of Canada, but I haven't talked to Bud in quite a few years, not sure if he's still in business. This list is probably the best resource. eBay as an alternative. If you get desperate I still have a few dozen low-split Micors in the warehouse, but really don't have the time (or patience) to deal with packing and shipping radios for what few dollars I'd get out of them (i.e. value of my time $value of radio).

Pulling it back apart isn't an issue with the 130C if you apply it sticky side out. Once you slit down through the vinyl and 130c with a knife, you can peel it apart to open up the splice. Yeah, its a little work to get it to release from the jacket of the cable... but its doing its job keeping the water out. It usually releases from the metal connector parts fairly readily.

[Repeater-Builder] Re: Measure return loss and cable fault with HP 8924C
First you'll need a return loss bridge. No replacing that. The 11807 software can make things a little prettier, but you can still do return loss quite easily. Distance to fault is going to be a bit more challenge, but it can be done too. Return loss is the easiest to set up. You'll need to set up the tracking generator/spectrum analyzer for the range you want to measure. Use the Duplex Output and connect it to the Source port on the RLB. Use the Antenna Input and connect it to the Reflected port on the RLB. You optionally may want to put a 6dB pad in between the Duplex Out and RLB Source port. With the DUT port open on the RLB, you should have a trace on the spectrum analyzer over the range you are sweeping. Now, you can turn up the output power of the Duplex Port until the trace gets close to the reference level at the top, or go into the menus on the spectrum analyzer and do a Save A and then a A-B to null out the sweep. Now, when you put a good load on the DUT port, you should get a return loss down ~40dB or so. Hook up the DUT you want to sweep and go. Yes, this is quick and dirty, but it gets the job done when you are not looking for fractions of a dB...
