RFinder M1 *update* from Bob W2CYK

A message from Bob W2CYK as of January 10th 2018 published on the Facegroup page.

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!

Have fun and stay tuned!

RFinder M1 Volume control using the hardware knob

We just received a great news yesterday in the Facebook group page for the RFinder M1 from Bob Greenberg W2CYK, RFinder M1 DMR volume can now be controlled by using the top hardware knob.

OK…This makes your knob work for volume of the radio! A bit complicated piece of code…watches for you to finish turning the knob for 1/2 sec then sets the volume according to the volume slider in the OS volume palette…volume slider disappears from front panel programming screen on M1…testing H1 next and then the K1…

Bob W2CYK

The updated file RFinder6-17-360_test.apk can be easily downloaded from the Facebook Group page.

I strongly suggest interested users to visit the website to learn more about the RFinder M1 and all the potential this DMR transceiver offers to the Ham community.

RFinder M1 *Update* 6.17.346

We just received a great news in the Facebook group page for the RFinder M1 from Bob Greenberg W2CYK, the M1 is in release candidate stage version 6.17.346 and seems to work great so far!

Release Candidate 6.17.346
This replaces older version 6.17.344 and earlier!

New or corrected features to test:  
1- Out of promiscuous mode consistently when a new station is tuned from anywhere

2- Promiscuous mode toggle button properly reflects state and also hides itself in FM mode
3- Screen wake on receive in promiscuous mode
4- Rounding error in memories fixed
5- Crash bug in locales with comma decimals fixed
6- Phone call turns off module, module comes back on properly with settings after call
7- While in Promiscuous mode, the TX stays on the previously programmed F, TS, TG, CC…you can TX but you will recieve on all…

NOTE: should ask for a new permission on install, monitor outgoing calls (that and reading phone state are necessary for the radio to work with the phone…

Tickets still open :
1-Volume knob
2- PTT cancel promiscuous mode seems technically unfeasible without a change to the RF module firmware.

73 de Bob W2CYK

As a short refresh, when the promiscuous mode is enabled, user can now receive DMR communication without the needs to enter a color code, talk group or even the time slot.

I strongly suggest interested users to visit the website to learn more about the RFinder M1 and all the potential this DMR transceiver offers to the Ham community.

RFinder M1 *NEW* Promiscuous mode and courtesy tone

We just received a great news this envening in the Facebook group page for the RFinder M1 from Bob Greenberg W2CYK, the new “promiscuous” mode for the M1 is in beta stage and seems to work great so far!

Screenshot_20171207-194837.pngWhen enabled, user can now receive DMR communication without the needs to enter a color code, talk group or even the time slot. So if someone would like to discover active talkgroup on a specific repeater, it is definitely a great add on !

The courtesy tone is also giving more feedback to the user when TX.

I strongly suggest interested users to visit the website to learn more about the RFinder M1 and all the potential this DMR transceiver offers to the Ham community.

RFinder M1 Android/DMR/LTE [part 2]

The RFinder M1 uses a USB cable with a special propietary connector to charge and to communicate with a PC.  The cable that comes in the box with M1 is the one that hold itself securely on M1 using a small thumb screw, like we could see very often on business grade handheld like a Hytera or a Motorola. It is possible to buy a spare USB cable that stay connected to the M1 using a nice magnetic connector instead.

To all technical users, I’d like to share these two pictures showing the pinout for the proprietary connector. The first picture is the pin out when using the cable to charge or communicate with a PC. The second one is when the cable attached is an external microphone.

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!

RFinder M1 Android/DMR/LTE [part 1]

Hi every one! I recently added in my gears the *no code plug needed* UHF DMR transceiver RFinder M1. Previously announced during Hamvention 2017, my first feeling, when I seen it at that time, I was impressed, curious… but I was not conviced to make the jump and break the bank to buy it. But a month ago, after reading good comments ont it, I changed my mind! When I received it a month ago, and now let me tell you that I am very conviced! 🙂

rfinder-m1-original.png First of all, the M1 is running under a customized Android OS version 6.0… not the latest release of Android OS, but a very stable one, and no bloatware are installed; only the essential and needed software. All users will be able to later install every sofware they need… so this is a good news! The LTE modem is also compatible with mostly all today’s LTE bands, at least here in North America, especially in Canada; I’m using Rogers Wireless service and it is working flawlessly so far.

Physically, the RFinder M1 is built like a tank… and I mean it! I already dropped it by accident, and nothing happen, not a sctach or dent… Nothing at all!! 🙂 Plenty of physical buttons, PPT for DMR radio, PTT for apps like Zello, another PTT for futur add-on feature and a red button located atop for futur feature add-on also.

rfinder-m1.jpg

The M1 also has a nano SIM slot and a micro SD slot for storage up to 32 GB. Both slots are protected by a waterproof cover. The 6,200 mA battery is also removable and protected by a waterproof battery door also, and offers plenty of power to work all day long on a single charge; spare battery can also be purchased at a later time.

The M1 is capable to deliver 1W at low power and 4W at high power and can be easily compared to any standard UHF handheld.

I will not go through all softwares features offered by the M1 for now. There are also plenty of reviews and videos on the Internet showing all the details of the great device!

It is very important to mention that all users or futur users must understand, the M1 is a well mature product ready to be purchased and ready to use, but it is also a great work in progress. The technical support is excellent, outstanding! And developpers are also listening the ham community for suggestions. This is very important to understand, because the M1 is getting better and better every week or so.

Developpers are very active and pro active to offer to all M1 owners the best experience with their device. The Facebook group is also active, and provide quickly the first support level : RFinder M1 Facebook Group links. I strongly invite every one to join the group!

The shipping is also extremely fast…. Ordered mine from http://rfinder.shop/. Shipped from China, it took only 3 days to my house in Canada!

So far now, I stronly recommend the RFinder M1 to all fellow hams who would like to have a versatile DMR transceiver and an Android phone into 1 device….. and also to avoid essentially dealing with DMR code plug that change very often.

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!

My VHF/UHF FM/DSTAR/DMR mobile installation

Hi, I just want to share with all of you my new mobile radio installation. The setup consist in an ICOM ID-4100 running on FM and D-Star on the VHF band, and a Hytera MD-652 running on FM and DMR on the UHF band. Both transceivers are connected to a duplexer, then to the Larsen dual band NMO antenna. We must admit that we do not have much space left in vehicule now, so we must take care to select proper equipments.

For the Hytera mobile, I am using a Hytera Bluetooth speaker microphone model SM27W1 to avoid the need to bring cables inside the car.

The microphone holder can also charge the internal Lithium battery while it is in place on the microphone holder. An USB charging cable bring 5 volt when the mic is place.

Both ICOM and Hytera transceivers are installed inside the car trunk. This way, no fan noise in the car, no need to find a place and also by keeping the RF cable path shorter than possible to minimize the RF loss. Both are easily accessible to let the operator to program both transceivers when needed. The duplexer offer sufficient isolation for a mobile use. The ICOM only works on the VHF band, and the Hytera only works on the UHF band.

I installed the ICOM ID-4100 transceiver controller head by using a homemade bracket made myself. I also use magnet to hold the controller in place, and it is easily removable.

I hope my installation will inspire a few hams… 🙂
