-
- This practice is common on NJ traffic nets. As a matter of fact, one net
- instructs its net controls to say the following :
-
- To check into this net, give my callsign, then drop your carrier
- to see if you are doubling with anyone.
- Wait for the beep, then give your callsign and say "no traffic" or
- list your traffic if you have any.
-
- (this is from memory, since I am not one of their net controls, I don't
- have a copy of the instruction.)
-
- Anyway, it usually does seem to work. After a while, people learn to
- say "here is", or give the net control callsign, at different speeds.
-
- When I first heard this practice, it sounded unnatural to me too, but after
- checking into several hundred vhf nets over the past 4-5 months, I've
- gotten used to it, and as I say, it seems to work.... IF the regular
- participants are used to it. It permits 10, 15, or more stations
- to check in without requiring individual acknowledgement.
- Then the net control simply acknowledges all of them at one shot.
- There may be two or three unresolved doubles, which are picked up on the
- second round. I have seen some sessions where 25 stations have
- checked in efficiently in about three minutes, including some with traffic
- to list.
-
- One alternative, simply keying up and making a transmission, more often than
- not, results in even more wasted time.
-
- A second alternative, each person having an individual interactive
- communication with the net control, as is typically done on
- old style non-repeater types of nets, would also seem to be less efficient.
-
- I'm not saying I like it, just telling it the way it is.
- It may be appropriate behavior on some types of nets, and not on others,
- but I wouldn't characterize it as heinous.

-
- The latest thing around here, and I hope it is not becoming

- the <beep>, then continue transmitting your callsign
- to check into a controlled net.
-
- Not only is this a waste of net time, it just sounds stupid.
-
- I can anticipate that someone will rationalize that this
- pause allows one to discern if he is doubling with another
- station trying to check in, a la W3HXF. It don't work!
-
- In fact, it is even worse than simply transmitting your
- callsign and shutting up because callsigns have variable
- length, "this is" takes almost exactly the same time
- to speak regardless of the speaker. So much for that argument.
-

- Don't confuse a walkie extender with a remote base.
-
- Proper remote bases are indeed duplex; it's up to the controlling
- station to equip itself with a duplex radio if it wants to take full
- advantage of the remote's capabilities.
-
- I'm not aware of any of the off-the-ham-shelf radios that can duplex on
- the same band. Modified commercial radios can do so in many cases:
- I've run Motorola Micors and Mitreks in that way.
-
- Some remotes have taken to having dual inputs and talkbacks on different
- bands (450/900, 450/1200, etc) in order to allow duplex use by people with
- radios that won't duplex in the same band but which can listen on one
- band whilst transmitting on another. It's essential to get the audio
- phasing correct so that the audio won't cancel when the user station is
- listening on both bands simultaneously.
-
- At home, it's simple to use two antennas for your base station to talk
- to the remote. With proper physical isolation, duplex is achievable on
- the 450 band at the standard 5 MHz split. My home radio is an old
- duplexed Micor, with a pair of small beams aimed at the remote on its
- mountaintop 30 miles away. The beams also help eliminate interference
- from the other remotes that share the channel with mine.
-
- Mobile duplex operation can be a bit more challenging, especially when
- you're running more than 30 to 50 watts output. Two antennas with
- broad pass cavities will allow duplex operation over a 1 to 2 MHz
- tuning range, which is sufficient for many communities. I ran this
- configuration for many years.
-
- For single-antenna operation, the typical CellWave-type mobile duplexer
- (a notch-only device) is still effective for half a meg or so, which
- may be sufficient.
-
- Unfortunately, my current car radio (an old Syntor) won't duplex
- because the synthesizer is shared by both RX and TX, and shifts between
- on-channel and LO at changeover. I'm seriously considering going to a
- non-synthesized radio in order to regain the mobile duplex, which I
- really miss.
-
- One point: if you're going to run duplex, get the best noise-cancelling
- microphone you can buy. Feedback is TACKY.

- In Santa Cruz, our club is about equally divided between
- the "old timers" and the "new hams". It's the old timers that
- time out the repeater (3 min) and step on the tail of the previous
- transmission. My guess is that this comes from DX pileup manners

-
- >By the way, by 'new' I mean those who weren't around before repeater beeps
- >were common! It wasn't that long ago!
-
- We had beeps before the new fancy controllers. It was the intermod
- and feedback generated when the repeater was talking to itself after
- the signal dropped on the input. Some of the early transistor rigs
- also had a nice solid DC transient when the squelch poped. The
- loud bang of the speaker cone trying to shove its way throught the
- grill was the clue that the carrier had dropped.
-
- >Even with no squealch tail, a person can determine when to speak. If this
- >wasn't possible, then people would have a lot of trouble communicating
- >with the telephone!
-
- One of my college psychology research projects was on this subject.
- We recorded "normal" conversation and measured when both speakers
- were talking simultaneously. I can't remember the exact figures but:
- Normal conversation 5% overlap
- Animated debate or arguement 10%
- My Polish relatives 30%
- TV political interviews 10%
- Loud party 20%
- My point is that with simplex or half-duplex radio, the art of NOT
- tromping on the other guy is unique and unusual and probably requires
- some practice. Methinks beeps don't make any difference. Whenever
- we have 3 or more hams engaged in a heated arguement, everyone steps
- on everyone else, beeps or no beeps.

- I'm not so sure. While returning from a trip, I had an auto
- accident occur in front of me. The only repeater available had
- a conversation running, so I tried to break in. Not a chance.
- Even though I could tell that I was being heard, I was being
- ignored. I didn't wait around and hopped the fence and used a
- payphone. (This was before commodity cellular phones).

- > Beeps breed bad habits!
- I guess so. However, there are many worse habits practiced on
- repeaters. The long winded monologues are disgusting. If you quiz
- the participants on the contents of their own transmission, they
- can usually remember on the very last thing they pontificated upon.
-
- The bad operating habits brings up an interesting problem.
- The local ARES organization holds regular SET (Simulated Emergency
- Test) drills. They give the most inexperienced hams the maximum
- amount of practice. The result is that the newly licenced hams
- hear only beginners on the air and proceed to mimic all their
- mistakes. Fairly soon, all we have are permanent beginners repeating
- each others mistakes. This is the way it works on repeaters. A
- new ham listens for a while, hears all the bad practices, and
- proceeds to do likewise. Perhaps this is how bad habits are
- propagated?

- It has for some time seemed strange to me that the technos in charge of
- a repeater would go to great lengths to eliminate the squelch burst
- (sometimes going so far as to install audio delays that absolutely
- cripple duplex operation!) and then have to go back and ADD a beep that
- does NOTHING that the noise burst didn't originally do.
-
- I prefer a repeater which has a modest user squelch tail and a 1-second
- dropout delay ("hang time"), and NO BEEPS.
-
- Want a useful 'over signal'? Substitute a burst of 9600 bps packet
- and transmit the repeater's complete system telemetry in the packet.
- It will sound just like a squelch tail - and has the secondary effect
- of identifying the repeater on every single transmission. NO MORE
- BEEPS!
