But on TV, it's all horizontal or circular/elliptical polarization, so you can eliminate one of the antennas and the hybrid coupler. And if you want omnidirectional coverage, you build a large metal box, and place one log-periodic array on each face, and then phase those together using a series of hybrid couplers. -- Kris Kirby, KE4AHR Disinformation Analyst

Re: [Repeater-Builder] Somewhat OT - How to make HDTV *really* work
It's not irrelevant when you want people to know that their DTV channel X may not be ON channel X anymore. People need to understand what virtual channels are. For example: Why is my local channel 43 interfering with my 6M repeater now? Well, if you don't know about virtual channels, then you're really going to have a tough time with that issue. BUT, if you learn that the RF channel used may not be the same as the virtual channel number, and you learn that the DTV channel 43 TX may actually be on RF Channel 2, the issue becomes much more clear. Why would anyone want to promote ignorance? (other than the government) BTW, needs fixed = needs to be fixed the same as needs said = needs to be said. The words to be are irrelevant aside from making the post longer. (or is that making the post 'to be' longer...) Joe M. wd8chl wrote: MCH wrote: You know, I just though of another example that needs 'fixed'.

If people can understand that the channel name isn't always the channel number on the cable systems, why can't they understand the same will now be true for DTV where 2 is on 25, 4 is on 51 and 11 is on 48??? It seems that the main source of the confusion is the alias that shows 02-1 rather than 25-1. The very item designed to avoid confusion seems to be the cause. Maybe we should just make it easy and make them use their callsigns again so you can know WTAE is on OTA Channel 4 (STD), OTA Channel 51 (DTV), and 3 (STD) or 210 (DTV) on cable? BTW, KPBS is on OTA Channel 15 (STD) and Channel 30 (DTV). It may show 15-1 as an alias, but it's RF Channel 30 for the DTV signal. Joe M.

[Repeater-Builder] Re: PL (CTCSS) Filter
Hi Doug, Many years ago I had a similar situation. Instead of using the N06B filter I used the built in hi-pass filter in a Comm Spec PL encoder/decoder board. It is very similar to the NO6B filter. What was happening was that the filter was introducing twist (subtle distortion) to the DTMF waveform. The solution was to connect the DTMF decoder directly to the discrimnator output bypassing the filter. You could then try put the filter in line the transmit audio from the controller. However this could be opening up another can of worms because I don't know if you are running flat or pre-emphasized audio and what the effect would be. 73 Bernie Parker K5BP --- In Repeater-Builder@yahoogroups.com, Doug Hutchison gb...@... wrote: Hi, Have built the filter circuit by Bob Dengler NO6B from the site.

[Repeater-Builder] Kenwood TKR 820 another question unraleted to the current question..
Seeing all this talk about the TKR-820 made me thank about getting the TKR-820 I have working again. I replaced this unit 4 or 5 years ago when I was working at a Kenwood shop due to the following. The repeater seems to work fine for a while 30 mins to maybe as much as 60 days and then one of the following seems to happen. The repeater will stop repeating upon getting to the tower site I would find the repeater in one of the following states. Rx'ing but not tx'ing Tx'ing (from local mic) but no rx No rx or tx at all I all cases there the power lite would be on and the front panels buttons and lites for each of them worked as you would expect. I only thing that would seem to get it going again was to turn it off wait 30sec or so and turn it back on, then it was good for 30 mins to upto 60 days or so. This repeater did this for a number of years and was gone thru multi times reprogrammed and retuned with no change. This repeater has been programmed with both a KPT-20 and a KPT-50 programmers..

Re: [Repeater-Builder] MSF5000 Squelch
You've got several more hours (or even days) of reading ahead of you! Thanks for the comments. The MSF5000 squelch is a single-level noise-based squelch system, much like the MaxTrac and most mobile radios. The squelch-tail duration is fixed. However there are two distinct and electronically different squelch circuits in the station: one for the Repeater, one for the Receiver, and they are independently set via EEPots. To confuse matters, the Receiver squelch can be set from the front panel Squelch pot instead of the EEPot IF the Acc Dis switch is raised. The only official way to tell if the squelches are closed is with a digital metering panel, as it has LEDs on both squelch signals. You can also measure the squelch circuit outputs with a DC voltmeter. The station's CW ID will NOT fire if either squelch circuit fails to close. Whichever way you're not using the station (repeater or receiver), then set its squelch EEPot to 99 or some high setting to insure they both eventually close.
