Hi all.
My 1st post.  I am thinking of buying the HCP-1 however before i do i want to make sure it is what i require so i am hoping you guys can assist me please.

Currently i use a MMDVM Pi-Star Hotspot and find if i want to use DMR then i have to use a DMR Radio, If i want to use FUSION then i have to use a FUSION Radio, If i want to use D-STAR then i have to use a D-STAR Radio.  Three radio's required to operate these modes.

If i buy the HCP-1, is this situation going to be the same or can i use just one Radio for everything?

Many thanks
Stay Safe

  No manual for the B1?
Posted by: Jimcausey - 07-23-2021, 11:47 PM - Forum: General Discussions - Replies (3)


I received a new B1. It's my only 2M/70cm radio. The red L.E.D. illuminates when pressing the PTT but none of the local repeaters respond and none are heard at any time. Is there some hidden function to enable the radio?

  SIM card removal, How?
Posted by: NE4Y - 07-15-2021, 03:27 PM - Forum: General Discussions - Replies (1)

So, I've had my B1 for 1 day. I pulled the SIM outta my verizon phone popped it into the slot in the B1. Was able to call and text no problem. Yea! Now, I want to put the SIM back in my "other" phone and I can't get the SIM outta the slot. Any suggestions? Tools I need. I am being gentle to no scratch the board or any connections, but I have been been very unsuccessful in getting it out. HELP!

  What's RoIP?
Posted by: k7gps.dave - 07-11-2021, 01:46 AM - Forum: Development - No Replies

I'll do the best I can to describe RoIP. It's not difficult to understand.

There are two ways to get your signals from your radio to its destination. Rota (Radio over the air) processes your voice input to analog or digital format, transmits it over the air to a receiving station, maybe or maybe not using the internet. The receiving station processes the analog or digital signal and hears what you said. Note, I just made up this acronym "Rota". It just makes RoIP easier to understand.

The second way, RoIP, if for digital signals only, like DMR, where the process involves changing your voice input to digital format, e.g. 1's and 0's, then transmitting them to a destination radio, internet radio or some other system. In RoIP, those 1's and 0's are compressed and packetized and sent via Internet Protocol over the phone's cellular data connection. There is no TX over a radio frequency, just conversion of the voice input to digital format and transmitted over the phone's cellular data connection. No repeater or hotspot is used in RoIP. Thus, the only necessary piece of info to be digitized is the DMR ID of the receiving station. When you want to make a call using RoIP on the B1, bring up the menu like you're going to input a new frequency, poke in the DMR ID you want, send the parameters, then switch from radio to IP mode using the grayed button. The B1 power button will change from RED to BLUE background, and the radio is ready for communications on the DMR ID entered. 

Note: You cannot use Promiscuous mode while using RoIP. At least, not yet. The plan is to allow a user to enter multiple, say up to 5, DMR IDs in the spot, then the radio would monitor those 5 IDs for traffic. Details are being worked on now. 

Comments solicited, please.

  New to DMR and B1
Posted by: Pepper - 07-02-2021, 06:59 PM - Forum: General Discussions - Replies (4)

Before I post this I want to thank you all for help ahead of time. I am new to DMR and the B1. I have had the radio for one week. No problem on the FM analog side. I am having problems on the DMR side. I have not been able to bring up a DMR repeater. I am not using a hotspot at this point. 
     How do I tell if a DMR repeater is functional ? Do I need to worry about talk groups or is there a general one that I need to use. Some are brandmiester  some not. Yes I have a DMR number it is in the radio. One of the locals suggested I need to register with brandmieast DMR. What general  DMR information or You tube do you recommend. I have see all of the you on the B1 that I have found. Thanks
