ICOM R75 scanner

[AGS]

Does the ICOM R75 scanner feature have the same capacity as any ordinary or advanced scanner? Is it to be treated like a Uniden scanner despite having the category of "RECEIVER" or "communications receiver"? Will it depreciate highly if I turn the SCAN button often? Thanks for the replies, guys.

The R75 is a HF receiver. It has no resemblance to any "scanner" that I'm aware of.

You might be thinking of the R7000 line, long since discontinued. While it did 'scan' after a fashion, it was painfully

This is a great radio to use to watch a single frequency. Get yourself a real scanner like from GRE, RS or Uniden to do the actual scanning of frequencies

Many thanks, guys..

I don't quite know what you mean by "Will it depreciate highly if I turn the SCAN button often?"

The Icom R-75 is a communications receiver. It is not really meant for automated scanning. And it covers from 60 MHz down to 30 kHz.

Yes, the R-75 has a scan function that will work in all receiver modes. Yes, you can store frequencies and modes in the 99 memory channels, adjust the squelch high enough to blank the background sound in all channels (the squelch is not channel specific), and press the scan button to start scanning your channels. The radio will stop scanning when a signal is detected that overrides the squelch setting. If Scan RS menu is selected to ON the radio will resume scan when the signal drops.

As ka3jjz says, it is not meant to be a scanner. It is a great radio to watch a single frequency with. However, it can scan, and that is of some limited use. Do not, however, think of it like a traditional scanner.

T!

(Edit note, I forgot that I built the Basic Stamp circuit not to resume scan, but to announce the frequency on scan stop, so I could record and know what frequency had been active.)

While 'scanning' as you might expect it to be would work between 30-60 mhz, don't expect it to work on HF very well. Any noise burst will likely trip the squelch and interrupt it.

Like I mentioned before, get a real scanner - not a communications receiver that happens to scan. The two are vastly different in applications and scope best regards..Mike

I have found it nearly impossible to scan HF SSB frequencies in memory such as say 11175, mars nets, aero, etc..beacuse the noise floor on HF is too jumpy and trips the squelch constantly. However, since the rig goes up to 60mhz, I plugged in all the 42mhz Highway Patrol frequencies for the SF bay area and a couple ranger outfits too-it acts just like a scanner with those, and the audio from the r75 with these FM frequencies is beautiful it has that "base station" fidelity.

R75 as "scanner"

Yes, I agree. I've had my ICOM R75 for 12 years now and I use it regularly. It's been a great HF receiver but you can forget about "scanning" HF single-sideband frequencies. It just doesn't work. One thing that I have done is to program only a few of the High-Frequency Global Communication System freqs (5, to be exact) and I set the squelch below the threshhold. Then I let it "scan" those 5 frequencies, with the autoskip set to 6 seconds. That way I can automatically monitor those 5 HFGCS frequencies and cover them all within 30 seconds before repeating the group. If I discover a transmission on one of them, I quickly reach over and turn the scan function off so it sits on that particular frequency.

If you live in an area where VHF low frequencies are still used, then you can write those frequencies to the memory and scan those as you would a regular scanner. But, there are fewer and fewer places in the country where VHF low is still used.
