Re: DMR Network with mobile repeaters...roaming!

Hello Patrick, Roaming is an enhanced form of scanning. A radio set up for roaming has a roam list containing entries for all available repeaters. It scans through this list until it finds a repeater that is above a preset signal level. It then uses this repeater for all transmissions until the sign...

Re: Decent Speaker Mic for the MD 380.

Buying external mikes can be a bit of a gamble on DMR radios. Many have poor RF screening which is a big problem as the pulsing TDMA signal can be heard in the audio. Many others have poor frequency response which can make the DMR audio very muffled. The Kenwood KMC-21 is reported to be a good micro...

Re: Just a little confused help please!!!!

Paul, Because the transmit and receive frequencies are different a good signal in one direction is no guarantee of a good signal in the other. This is especially true when the signal path is obstructed. Your antenna will have different characteristics on the two frequencies and the pattern of peaks ...

Re: Just a little confused help please!!!!

Hi Paul, The range you can expect is the same as from an FM radio. Have a listen on the DMR repeaters frequency with an FM radio. If you can hear it then you should be able to work it. DMR does give clearer speech at low signal levels but the ultimate sensitivity of the radios is the same as FM. Pho...

Re: Now part of Phoenix?

The Northern DMR cluster remains as a separately managed network. They have however requested to interconnect that network with Phoenix to gain access to some of the wide area Talkgroups. The connections you can see on the Phoenix status pages are the connections set up to provide those links.

Re: Chertsey Radio club testing new DMR hand held

Hi James, I have to agree with Mike, pre-programmed radios with no cable supplied is not the way to go, I would encourage you to include a cable and software with every radio. The DMR networks are constantly changing. Being able to re-program your own radio to accommodate these changes is an essenti...

Re: Taken the plunge!

Hello Terry,

If your location is correct on QRZ.com then you might get a better signal from GB7NS than from GF. Either way welcome to DMR.

Re: Ging around in circles

You need to select clone instead of write. That will write the Codeplug to a different serial number. The model number must still be the same though.

Re: TYT MD-380 - Reception Issue?

Yes, a large receive group can help monitor the activity on a repeater. It can however cause some confusion if you try to reply to the calls you hear. Most radios will reply on the incoming Talkgroup but only for a couple of seconds. Then it will revert to the programmed talkgroup. So it is best to ...
