RFinder Android Radio Quick Start

I am Bob W2CYK and thanks for purchasing the RFinder Android Radio. The RFinder Android Radio is a new paradigm in radio technology. It is based on the Android operating system and therefore is a complete smart device, including Cell, 70cm FM and DMR all in one.

First, join on Facebook the RFinder Android Radio group…in the files section you will find a lot of information. The RFinder software and ROM is constantly changing and we welcome all our new users to the design team! If you do not have a Facebook account and do not want to participate in FB generally just limit your account as you like once you create it. There is a setup video and this document in the Files section.

Power up your device and attach to WiFi.

Setting it up is easy. Just go into the Settings icon and enter your Gmail account and password or create a new one if you do not have one. Install the RFinder app from Play (or the Facebook group may have a later test version you may want to use). Open the RFinder app and enter your name, call sign, RFinder email and a simple password you will remember. This email and password will be used in any access of RFinder; on the web, in RT Systems, CHIRP, etc.

DMR ID

To use DMR you will need a DMR ID…if you do not have one request one on https://dmr-marc.net/cgi-bin/trbo-database/register.cgi it could take a day to get that so be patient. Once you have your DMR ID, open RFinder on your M1 and Power on the radio module. At the bottom of the RFinder there is a Power button between Call and Map buttons. Press it…wait for it to become red. Touch the section at the top with the RX/TX frequencies. Enter 441 for both RECV and XMIT frequencies, and your DMR ID. Press SEND PARAMETERS button and press CLOSE. Press the power button again to turn the radio module off and then press it once more to turn it back on. This commits your DMR ID to the module’s EEPROM.

QRG Offset

Most DMR radios and hotspots are slightly off frequency. RFinder has an adjustment for this by accessing Menu-Advanced. If you use a service monitor or digital frequency counter just adjust it opposite, so if you are showing 100hz off, just enter -100 to adjust, etc. This approach is different from other radios that have no adjustment. This is why hotspots have a QRG or Modem Mode adjustment, to allow for this. You can set your Hotspots for other radios you may have and then adjust the RFinder Android Radio to match that or just set your Hotspots at 0 (or Mode A for an OpenSpot) and adjust the QRG until you get good audio on a receiving radio or by listening to the Brandmeister hoseline scanner for whatever group you are using.

The RFinder Menu

You can find the RFinder menu by swiping from the left edge of any RFinder app on any device.
Memories:
While the RFinder Androids have no Code Plugs (they automatically update themselves from the RFinder system), you can create virtually unlimited zones and memories on the fly on the RFinder programming screens. For instance you can create a memory for your favorite TS/Group combo on your favorite repeater and call it whatever you want.

Setting up your SIM:

In US, AT&T and carriers that run on AT&T’s network are supported. Outside US, nearly every major carrier works just fine. You will need a Nano-SIM for the M1/K1 or a Micro on the P1. Put your SIM in the device and reboot…follow the following to enable it…
1. Open Settings app.
2. Click SIM cards…turn on the SIM for Phone, Data and SMS…go back one level
3. Go to Data Usage…click the tab for your carrier and turn on Cellular Data…go back one level.
4. Click More…Click Cellular networks…turn on Data Roaming (in most cases), Turn on Enhanced…click Access Point Names
5. For AT&T US, choose NXTGENPHONE…for other carriers, follow your carrier’s instructions
6. You should be on broadband now…if you are connected you will have something like 4G4G or 3G3g…the superscript shows you are connected. If you are having trouble, visit your carrier or pose a question on the Facebook group.

SD Card:

Just put one in…we have tested up to 128GB MicroSD’s…you have the choice of formatting it as Internal or Portable storage…Portable you can take it out and add stuff to it; Internal the card extends internal memory. Internal is suggested.

External Mic:

If you purchased the External Mic, charge it with the included cable. Then attach it to the screw lock connector on the side of the unit. The button on top powers it on and off; the button near the PTT changes volume…click it each time changes the volume. You cannot charge the device with the Mic attached.

External battery sled for M1:

Just plug it into a 2a USB and insert the battery. The lights will indicate the charge level.

External charge doc for K1:

Just drop the radio or battery into the doc to charge it. The included USB cable provides your charge source.

GPS:

Sometimes it is slow to get a GPS lock…we find it helpful to install the app GPS Test, which speeds things up a lot. You can also update the AGPS data using this app.

I will post more information on the RFinder M1 in my blog soon…. I’m still digging into it everyday…. a great DMR handheld so far!

Meanwhile, do not forget to follow me on Twitter @VA2SS, and subscribe to my blog and my YouTube channel as well.

Have fun and stay tuned!
