Re: [AMRadio] Zero beating
From: Todd, KA1KAQ <[EMAIL PROTECTED]> Another side of it though, is the SSB stations who zero-beat an AM qso and interfere that way. Had several doing this last week. So some of the guys tune just slightly off one way or the other, to make this a less-desirable option. But we're talking a few cycles, not 5-6 kcs. Sure, they can notch out the main carrier, but notching out several slightly different ones isn't quite as easy. From what I heard last night, the increase in phone spectrum won't stop the few lids who want to intentionally interfere. They sought out AMers no matter where they went. It's not a space issue for them, it's a poor attitude and minimal (if any) education. Then the slopbuckets intentionally zero in on the AM carriers, it's time for the old tactic Timtron calls "exit stage left." Otherwise, I agree it's good practice for everyone in a QSO to stay zero beat. My only problem is that with some antennas, the VFO signal isn't strong enough to hear in the rx and I have to temporarily switch to a different antenna while zero-beating.

RE: [AMRadio] Zero beating
Its easy to be critical. I hear and have worked people way off frequency, over modulated, way under modulated, people with really wide signals, people with truly nasty sounding audio, etc. Some don't like to get reports of the above, and will not believe such a report. Others are more open minded. Some run old crazy lash ups, or develop a problem while on the air, and some ricebox rigs have odd frequency offsets. I run a freq counter (you can get one cheap), used to use a ricebox exciter with a digital frequency display, scope to look at modulation (both TX and RX), and a mod monitor with audio output to the headphones. Others just have a DX100 and an old receiver that only displays what PART of 40 meters you might be on... Now that I am using a 32V3 as an exciter, I check the TX freq often, it does not drift much, but you never know...

Re: [AMRadio] Zero beating
>Brian w5ami says: >Zero beating is just one way we could improve relations with SSB ops, >and ourselves... Reply by Jim, WD5JKO One nice thing about the Central electronics 20A is the 'CAL' position. In this mode, you spot the VFO to the received signal, and there is enough RF output to drive a frequency counter. This is done without keying the TR relay. There also is a level control so you can better match the transmitter VFO spotting level to the received signal level. This way an S-5 signal can be zeroed to just as well as an S9+40 signal. The VFO operates continuously and is beat against a 9 Mhz crystal. Keeping the VFO running, and out of band is pretty nice. My VFO, a CE modified BC-458 drifts down about 300hz from a cold start (80m). The biggest problem I have in a round table is knowing who to zero beat. Then when the long skip comes in, and I am talking local, I often find that zeroing to the long skip signal helps ease the local copy. If we "channelized" say every 5 Khz, then we would all know what frequency we should be on, i.e., 3880, 85, 90, etc. No 100% answers for all situations...

Re: [AMRadio] Zero beating
When we can't get some stations to clean up their signals, why would I want to start another controversy? I have heard stations say, "I am crystal controlled". So if there is activity on 3.878 real wide and I start up on 3.881, what should I do? I try to be reasonable about this, but sometimes my old hands can zero on my 755A VFO. I do promise to try though. 73 Jim W5JO I have a BC-221 here along with a freq. counter coupled to it. The 221 also couples close enough to my rx where I can use it to zero beat a signal heard and at the same time see the freq. on the counter. If the osc. in the tx does not get it perfect, I can immediately tune to the correct freq. I zeroed on the 221/counter as soon as I transmit. The Bc-221 is a handy piece of gear that many hams used to have as standard equipment, and can be found at hamfests for little money. I paid $15 for mine about 7 years ago. The freq counter was less than $50 used.

RE: [AMRadio] Zero beating
For what ever the reason is, "Zero Beating" has always been problem. Certain people would complain about it back in the 60s. Or I should say the lack of zero beating has been a problem. Sometimes guys would be so far off frequency that they couldn't be heard. I have had a couple of rigs in the far past where the VFO zero beat in RCV mode was a KC or more removed from the XMT frequency. The trouble with one of the VFO's keying circuit was that it was keyed via the oscillator's cathode circuit. (Heath Kit I think) Anyway the spot switch on the front of the VFO had less resistance than the circuit that keyed it from the XMTR. The quick cure was to switch the VFO spot on before going to XMT mode. The next one that gave me trouble was a pulling VFO. That is RF was getting back into the VFO and pulling the frequency. XMTR tuning would change the VFO frequency while on the air. Amplitude Modulation of the final would cause the VFO to FM. The cure for this was to make the VFO double in frequency. That is to set the VFO to a 160 MTR frequency and double some where in a buffer stage to have a XMTR freq on 80 MTR. This is a good idea in any home brew XMTR project. Last trouble that you see the most of is power supply regulation. Both filament power and plate power to the VFO must be regulated stable. Too many times with store bought equipment, these things are overlooked and ignored. And I think there in lies 50% of the "ZERO BEAT" trouble. The rest of the time, when guys are off frequency, it is just plain carelessness and occasionally they are rock bound and not using a VFO.

Wonder how it would have come out if it had been good old CW against good old 100 wpm narrow shift RTTY? How about PSK 31 or any of the other digital modes in use today by hams? It's unfortunate, but the powers that be tend to ignore the obvious, in favor of something 'better'. Cell phones work much 'better' than trying to use a 2m CB for example, and require no license. Unfortunately, as soon as there's a disaster, the local sites overload and are useless. This was proven by the USAir flight that burrowed into the ground near Pittsburgh a few years back, and again more recently with 9/11 as well as storms and other events. CW still gets through when nothing else will. More recently, when the Russian sub Kursk went down and communications were lost, the trapped crew used Morse to tap messages through the hull. Many other examples exist, they just tend to get ignored. It's nice that we have the newer technologies available for use, and even better is the improvement they provide over the 'old way'. Still, it doesn't make them a replacement. Too many are willing to throw the baby out with the bath water, only to regret it later when the new system doesn't work well in all situations. Jim makes an excellent point, even for the AM community: ham radio exists now mainly due to its public service credentials. Some experimenting still goes on, but today's technology makes it more limited for the average, curious ham. Having spent almost a quarter century in this aspect as a foot soldier, then State RACES director, now foot soldier again, I can say that those who do the work appreciate the contribution of hams along with their commitment of time, energy, and their own equipment. Think about that the next time someone refers to the 'hobby' aspects like they are the only reason.

Re: [AMRadio] TS430 as VFO on a KNIGHT T60
Jack, You bring up a good point. I don't know if the TS-430 has an auxiliary audio input or not; usually for a phone patch. If it does, then do your audio remotely with whatever Mic you want, compressor, equalizer, etc. and pipe it into the remote audio jack. Then tee off that input to drive the 'X' axis of your scope. Keep in mind that this approach will only work if there is minimal phase shift over the audio range (100-4000hz) between the remote input and the balanced modulator. If the TS-430 does not have a remote audio input, then surgery is required to tap into the audio driving the balanced modulator. Once done you can inject high level audio from an external source as well as sample the audio for the scope.

Re: [AMRadio] Phone band expansion gone off topic
The disadvantage that the cell phone text messaging had against cw is that the entire message had to be typed before transmitting, kind of like a store and forward process therefore a lag in data receipt. I don't see how any of the systems Jim mentioned would be any faster if you account for the time it takes to capture the data prior to sending. CW is instant. I think that the whole idea of that contest on the Jay Leno Tonight Show was to demonstrate that some old processes still work well today. But...one thing to consider is that to send a cw message the receiptant must also know cw(thousands of people), whereas I can send a text message on a cell phone to most anyone who speaks the English language (millions of people).

Correct there was Brian, telephone texting vs. good old CW. Wonder how it would have come out if it had been good old CW against good old 100 wpm narrow shift RTTY? How about PSK 31 or any of the other digital modes in use today by hams? Not so fast, Jim... Actually there was a video from a TV show recently where a ham sending a message via CW got a message through FASTER than a digityal message sent by more modern technical means. I am sure many of us saw that. It was shown on a national televised show. It made me VERY proud of our wonderful Samuel "F.B." Morse and his simple code that has so enriched the lives of countless ten thousands of hams! Yes, morse code won the speed test, and this was within the last year or two! Prior to the 1980s code was the preferred method of emergency communications because of reliability. Today that is fluid. There are much faster ways to communicating written messages and instructions now in use. __ AMRadio mailing list List Home: http://mailman.qth.net/mailman/listinfo/amradio Partner Website: http://www.amfone.net Help: http://mailman.qth.net/mmfaq.html Post: mailto:AMRadio@mailman.qth.net
RE: [AMRadio] TS430 as VFO on a KNIGHT T60
My two cents... Its rare a controlled carrier rig sounds good. For myself, I don't want to run something that sounds like crap, no mater how vintage or efficient it is into an amplifier. I also seem to have given up on low power, and don't want any rigs that run 100 watts or less, except as exciters for bigger RF decks. A lot of this stuff is fun to play with, but as a rig you want to use on the air, they don't usually cut it. In my case, the small stuff just sat around the shack or got used once every 6 months for 10 minutes till I switched to the bigger rigs. There are guys who love using the old small rigs though, running a DX40 or DX60 with an outboard VFO and/or modulator, into an amp, and a crappy receiver with an outboard IF and rf amp, and outboard audio, etc. I suppose it's a challenge they like... Something for everyone on AM!
