Description of LCD BT Microphone
The LCD BT Microphone BHM-78 is available in 2 HiVis bright colours bands yellow or orange. I found it
feels comfortable in the hand and its lightweight, with buttons easy to find and use in the sturdy body as
the standard Vero equipment. Fits nicely in a pocket or using the latching belt hanger which locks it in.
The pairing of the BHM-78 to the phone was easily done and the top indicator light flashes during pairing.
You can switch easily between radios, if you have more than one. It does notifying you if you’re out of BT
range of the radio and when back in range of BT via bleeping tone and LED on top..
In open air expect 20 to 30 meters BT distance which is the same as mobile phone to VR N7500 radio.
If you move out of range the audio will go digital, bleep and stop showing “no signal” on the BT
microphone BE-78, moving back into range it will bleep and reconnect to the radio easily.
Pairing is via the screen or the top LH button (double Click). The button is easy and a single click gives FM
radio frequencies.
The control display is bright and easy to use on the same panel/theme layout of the phone Android App
with similar settings which change on the app as you change them on the microphone.
The audio is good and strong with recommended setting up before using on air as the audio is load and I
found the best setting was low audio level for the microphone TX best.
Having the reset the zone to UTC the internal GPS quickly showed the correct time and date, location &
height receiving GPS within the radio shack. It has speed and direction on the screens plus temperature
within the microphone.
I was able to switch easily between the 2 * Vero VR N7500 radios, where it picked up the memory channels
already held on each of the radio, so no reprograming required.
Note* changing of memory banks requires the phone to be connected via BT to the radio for the memory
bank to be changed as it’s not held in the LCD micro microphone.
There is a good charging port on the bottom of the detachable battery with led indicator Red/Green for
charge condition. USB cable “C” type is included and fits/charges whichever way it’s plugged in. The charge
holds well lasting a long time as it’s only the GPS, screen and BT load.
Changes made on the LCD screen or app change immediately on the other - vice versa.
The BHM-78 has sealed buttons and battery mean that it can be used in adverse conditions and the bright
colours make it standout and easy to find. I didn’t try submersing the BT handset. But with the battery and
ports with covers internal damage is very unlikely in the harshest of conditions.
I found that Kenwood & Baofeng style microphones works well and tried a BT headset plugged in the side
and a separate PTT worked well when audio input set correctly and not over driving TX audio. The port is
accessed under the sealed RH port cover.
The microphone will connect to Vero N range radios VR N7500 and Handheld VR-N75 and
was tested on each.

My Impression
I was very impressed with the new BMH-78 Bluetooth microphone and a great addition to the Vero range
of radios, once setup and finding the best level of TX audio (low)
which you change on the App Device Settings and the device speaker
set high so that you have plenty of volume work to with on the new
microphone. Low TX audio stopped BT overload reports on testing.
The distance for BT was as good as expected in the open and the same
as the phone App 20-30 yds/meters in line of site. BT reconnection
was automatic and the shown connection on the screen is good.
Reconnection of BT to other radios was very quick and simple.
GPS lockup was quick and held the signal in the radio shack of the
house.
I now prefer to use the BMH-78 instead of the phone and turn off the phone app as the 16 stored channels
were found to be sufficient for me. Loading up a new memory group if needed from the phone app.
If the radio and BMH-78 were used at an event/emergency station the volume can be load and clear,
hands free and even a headset, no wires, slips in a pocket allowing movement and convenience of flexible
operation in the VR-N7500 or the VR-N75 handheld (VHF or UHF). Being water resistant in a good solid
case like all Vero equipment I have seen and used this is a keeper and will be mistaken for a small handheld
radio creating interes when we can all gather together again.
Any software updates will be done automatically via the internet and wifi like the N7500 & N75 from the
Vero manufacturing support team which have been excellent.
