We have a 600kHz (+) offset. Very simply, our main problem is when we run the transmitter at full power 100 watts, there is a HUGE desense on the receive side of things. When we drop the transmitter power level to around 20-50 watts, the receive side opens WAY up to a large area where people can get into the repeater. As we begin to bring up the transmitter power, white noise begins to appear and the receive side starts to desense again. All the cables have been switched to double sheilded cables and all the same wavelength in length. We have the duplexer seperated sheilded from the transmitter preamp parts. We have not replaced the antenna feed coax with double sheilded coax yet. Antenna is a Hustler G7 atop a 55' mast. The duplexer was retuned just over 1 year ago. Any suggestions as to what we could look into next? Some of us believe the problem is with the tuning of the duplexer receive cans. Thank you very much. ---The WP-639 is spec'd at only 80 db of isolation @ a 600 kHz split. At 100 watts, that simply isn't enough to prevent desense.

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.

Re: [Repeater-Builder] Re: A warning to Land Mobile Radio Dealers
Back when I owned a strictly 2-way shop, we used to sell radios to local LEOs, programmed on the PD's channels all the time. Of course, the local Batwing MSS didn't like us doing that (we sold a competing brand) and got the C.O.P to write us a letter telling us how what we were doing was illegal (the claim was that we can't sell radios programmed on PD channels). This was during the late 80's and through most of the 90's. I wrote the C.O.P. back, explaining that it was perfectly legal for me to sell radios programmed on ANY frequency I wanted to ANYone. But of course, being the responsible member of the community that I am, I would only sell such programmed radios to authorized personnel only. We never had another bit of complaints from the PD although the MSS didn't like us one bit (too bad - I made a career out of tweaking the Big M).

The replacement RF deck is a Kenwood TKR-850 Series I. The previous RF deck was a KSG-4500, operating in a plain, dumb, duplexed TX / RX mode with no internal controller, PL decode, etc. I used the ComSpec TP-38 in the repeat audio path following the Hall voted audio to handle PL encode-decode, TOT, carrier delay/squelch tail, etc. Reading from the Repeater-Builder site, I came across the following comment regarding use of an 850: If you are using an external controller you set it to duplex base mode, with COR on Aux out #1 and TOR (tone decode) on Aux out #2. I would very much like to eliminate the need for the TP-38 external CTCSS unit if at all possible, instead utilizing the TKR-850's INTERNAL PL encode/decode capabilities, carrier delay, CW ID, etc. My questions is: If I program the 850 from repeater into duplex operation, do I lose all those features normally found in repeater mode, rendering the 850 back to a dumb radio like its predecessor? Assuming those features DO remain, how does one break the normal, internal repeat audio path, since it will be necessary to route local receiver audio out to the Hall voter for comparator operation? ---Bottom line Mike is yes.

[Repeater-Builder] Someone want to spot me?
Ok, so here's the deal I'm running a high power UHF repeater that transmits on 442.675 (60 watts out of duplexer). As part of the same system, there is a link receiver on 434.xxx. The link receiver is being de-sensed by the repeater xmtr (I'm guestimating around 6 dB or so). While I consider a better radio for the link, I'm thinking of a quick solution. As I have some extra Batwing T-1500 series cavities laying around, I'm thinking about terminating one port with a 50 ohm load and T'ing the other port into the link receive line and tuning the cavity for (obviously) 442.675. I'm thinking cable length between the T and the cavity is kinda irrelevant in this case. Sound about right?

I am at the very low end of what the repeater will program to at 147.060 and I can't get the right voltage on the Test Point by tuning the capacitor. The voltage is well below what it should be. ---Must not be a K2 version. Is it a K? But no, it does not need to be connected to a PC in order to align it Ken -- President and CTO - Arcom Communications Makers of repeater controllers and accessories. http://www.arcomcontrollers.com/ Authorized Dealers for Kenwood and Telewave and we offer complete repeater packages!

Re: [Repeater-Builder] Station ID volume on kenwood tkr 850-1

I'm a complete newbie at this, and not even at the repeater site. I downloaded the manuals (tkr-750-780-programming-v101.pdf tkr-750-850- function-v101.pdf) but did not see anything there about controlling the audio volume of the station id. Is there a way to turn that down?

Contrary to mythology, you do NOT need the special (expensive) Kenwood programming cable. Any ol' straight through serial cable, connected to the DB25 on the back of the TKR, will work.
