Navman 7100 Radio

[brucehawsker]

When I am on dual watch scan (67 and 16) I find my transmissions to the Coastguard are garbled. If I am on 67 only, they are fine. Is this what I should expect?

Only if you don't buy an Icom.

NOW can I have a discount, Jon?

Dear Mr Brooks,

I am not sure I find gloating that helpful !

Seriously, if Icom had a product ready for my build, I would have bought it. But your low price product, though announced, was not avaialble. Nor was Raymarine's.

My reason for the Navman was:

I was a complete beginner and did not expect to use it much
I wanted DSC as a safety precaution with a 15 year old son, and both of us being out together as beginners
Budget - if I found I nedded more I could invest in your £600+ box

This one seems to work fine in most circumstances. The manual is horrible - written for anyone but a beginner.

Most likely I have screwed up, not the unit.

If I set it onto Channel 67, and press scan, it tells me it is monitoring 16 and 67, and it is because I can follow converstaions which strart on 16 and move to 67.

If I talk to Solent on 67, when the unit is not in scan mode, they can hear me fine.

Problem seems to arise when I press the mic and speak when the unit is in scan mode monitoring 16 and 67.

Any ideas, Jon, or anyone?

Thanks

Bruce

Hi Bruce

My first impression of this set are very good.
Seems well built and easy to use.

Interesting fact/story......the new Raymarine is built in the same factory!

My test for ease of use is to go an a stand at a show and play with the unit.
If I can fly it with out a book, its good.
I could with this unit.
There are a few that I cant, maybe its me

To date I have heard of no faults with them.
So was over the moon to hear someone had a problem, sorry it was you!

If I had to make an educated guess I would think it is a processor problem of some kind,.
But with out hearing it is hard to diagnose.
Does it happen on all channels if you are scanning/daul watching.
Try it on a few othe channels.

Speak to Mark Larkin at Navman UK.
Nice bloke, should be able to help you out.

Hope that explains my gloating!

Hope you get it sorted.

Normally, if you are on d/w and need to transmit on 16, you MUST cancel d/w first.

Agreed. Brian beat me to it.

Aha, getting clearer now. If on dual watch 16/67 and I want to transmit, the rule is I have to stop dual watch. Yes?

If on dual watch, the screen shows 67, but set is listening to 67 and 16. If I transmit in this dual watch mode, it is garbled.

Is this because:

1) I am wrong to attempt to transmit in dual watch mode, and this is plain stupid ;
2) Tranmitting when 67 shows means a transmission on 67, even when 16 is being listened to, and (a) 67 happened to have interference when I tested the radio, or (b) my radio may have a problem transmitting on 67

I understand that if I want to call on 16, I need to come off dual watch and thumb the '16' button.

Thanks and sorry to be so dumb!

Not stupid at all - you should be able to transmit on the user selected channel, (ie on channel 67 in this case) but not, like Brian and JW state, on 16

2) Tranmitting when 67 shows means a transmission on 67, even when 16 is being listened to, and (a) 67 happened to have interference when I tested the radio, or (b) my radio may have a problem transmitting on 67

Sounds logical.

Correct.

Certainly this is how our "old" Icom M59 Euro works.

If you haven't made contact with Mark Parkin by Monday i'll post his number. Unfortunately, as I'm not at work, Mark Parkin's card isn't in front of me.

Eventually discovered I am an idiot! RTFM. Had 16 on high power (the default), and 67 on low power (also the default) when in the dual watch mode.

When I put the 67 as the only channel (off dual watch) I originally manually over rode the default to high power, since I had noticed it was in lo power. This is remembered by the set, so whenever you go into only chanel 67, it selects high power. So it worked fine.

Back into dual watch, and 67 drops back to the default dual watch low power on 67 (which is hard to see as it goes lo / hi on the indicator rapidly as switches it 16 / 67) unless you set it to high power when in dual watch mode. Then it remembers and stays in high power the next time you move to dual watch.

It does say so in the manual......
