Using the T1M and 35W radio as repeater

Nate. You need to embrace your local cell network and you will drop all the warm and fuzzy feelings about UHF. That is if you have a decent network. I normally work in an area that has cell. Every so often I have to use UHF and the whole time I think to myself that I'd rather be on cell. It just flows better.

There are some minimum separations between the radios that are recommended to prevent data loss:

What I was thinking of something along the lines of using as a reporter halfs the broadcast time, as you are also receiving, so your corrections are coming at a slower pace.

I may be mistaken though.

Another thing, can it be on the same freq, or does the repeater have to receive on one frequency (channel) and broadcast on another?

I think what we all want to do is if we are running out of radio from a base, is just to toss up the repeater and have it extend the radio range without messing around with anything else. It isn't as easy as that.. yet.

The repeater will work at 1 Hz which can be upsampled to 5 Hz. A repeater can't be used with corrections broadcast at 5 Hz but this isn't an issue with upsampling.

It works on the same frequency.

It is this easy now already. You just need to configure the repeater one time and it will still continue to operate with that configuration after turning it off and then back on again. If you don't change the frequency that the base is broadcasting at then you only need to turn the repeater on and it will start working.

Matt, for those of us using the 35 watt at the base with the T2, will the 401BT be able to be used as a repeater at this time?

No local network.
I'm on my own, for corrections.

Yes, corrections can be cellular.
And, even handy, at times.
Fully 50% of my jobs have places "where cell dont go" but radio is fine.
24" pines.

With Matthew Sibole's help, I finally think we have my HPT435BT radio working as a repeater and based on everything I've read, there seems to be no reason to not use it as a repeater all the time.

Can anyone who uses this setup (T1M/HPT435BT) share some pointers/tips? Does the 164' minimum distance "have" to be closely followed? There are certain places here and there we go to that it could be difficult to get separation.

If the T1M and the 35w radio are close - about the 165'+- - do I select the very lowest output power for the 1w radio 30(15)?

If somehow the 1w gets set and started at full power 1000(30) and the 35w is set up about 200' away, what could we expect to happen? Radio probably would start going out at the limit of the 1w and the 35w not pickup and properly repeat" the signal I would think.

Darren,

When I used yellow brand and repeaters at max base setting i would want to be a minimum of 1000' from my base for the repeter to work properly. If you're trying to get farther as last ng as your rover picks up a good signal at say 3000' it should work.

Mathew Sibole told me that if the 1m is at its lowest setting the repeater could be next to the base.

Let me know what works good if you don't mind. I would like to have mine set up this way.

Hope this helps,

Clay
