Theoretically. Truth is, it depends on how good the filter is. If a
guy is 40 over 9 just a few KC up/dn the band from the edge of your
filter, you'll likely know it. Every filter has a "quality" number,
both in ultimate rejection, and in shape factor (how steep the skirts
are). But, given normal signals, you should not hear anything outside
the filter edges. BTW, a 500Hz filter does not mean it will pass plus
and minus 500Hz. It means it will pass 250Hz each side of the center of
the 500Hz.

Re: [IC-7000] icom 7000 book for dummies

Hi John

Soon after purchasing my IC7000 I was advised to buy one of N6FN's
"The Nifty mini manual".


It is a brilliant buy, condensing the official ICOM manual into a
series of simple steps to set up or adjust specific transceiver
facilities.

After 4 yrs I still find myself using it when my brain refuses to
remember how to do something.

Not quite. It shouldn't sound garbled, you just won't hear it, unless
there it filter leakage. It shouldn't be garbled unless you are using
NR. Another can of worms. :o)

I opened it up to 2000 Hz last night and it sounded like it normally does…

John V. Nelson ? KD8TZC
For everyday operation, I generally run 400 Hz. It provides good
selectivity without sounding too harsh. In contests, or when operating a
DXpedition with my 7000, I will often narrow it down to 200 Hz or so, to
be able to pull out a single signal from the pileup. On other radios
(e.g., my IC-7600) I will also engage the Audio Passband Filters (a
second set of filters in the audio chain, beyond the regular filters in
the IF) to really clean things up.

If you are operating totally "in the clear," i.e., no nearby signals and
good signal strength, you can open the filter up to 1 KHz or so and it
will have a more "natural" sound, to most people's ears.

Hi the signals you hear are not morse or CW which is set in carrier on carrier off but in afsk cw is usually sent in FSK which is carrier on carrier off. AFSK uses a applied tone oscillator.
so that is why it is received as a LSB or USB signal.

Re: icom 7000 book for dummies

 

Yes there is a book Ham Radio For Dummies. You can order it from Amazon. It is a very general and basic book but probably not a good book to learn about the basic features of your ICOM 7000. I found that the preamble to the chapters in the ARRL Handbook much more informative about what things do and how they operate. Of course the ICOM 7000 manual is a great source of information but assumes you know something about ?what things are. I think between the two you should be fine. For how to be a ham operator the ARRL books excel there too. Hope this helps.

Check the filter bandwidth settings (both high and low) and also IF shift in case they have been set to some unusual values. Could easily cause the muffled sound you have.

You need to have the AMBE board or an AMBE chip built into the DV-RPTR board to use it to convert your IC-7000 into a D-STAR radio.??? You also need a means to program callsigns into the board - PC or similar.??? It is possible to have a preset callsign configuration for PC-less operation.??? I believe they were also working on a compact control unit, suitable for mobile use.

Yep, no issues.? Signal polarity is "normal" for Tx and Rx.? Use the data port, make sure the radio is configured for 9600 bps and in FM mode.? I used the second (10 kHz) IF filter.? Haven't had a chance to confirm if this is the best filter for D-STAR, but it seems to work.? Note that if switching between filter 1 (16 kHz) and the others, you need to change the amount of drive from the DV-RPTR board, because the radio configures itself for a different deviation (wider) for filter 1.

Interface is a G4ZLP with CAT (i.e. CI-V) support, and a separate serial port for PTT (I don't use CAT PTT unless I need to).

I've also used a DV-RPTR D-STAR adapter into the data port, and again, no issues with PTT.
