DIGIMIKE from PRESIDENT

Photo: New DIGIMIKE from President

Since many years President is producing CB radio’s with electret microphones and a standard 6-Pin connector. Big advantage is that all modern President 6-Pin electret microphones can be used on all President CB radio models.
Electret micro elements need a voltage to function and in the President system this voltage comes direct from the radio. One of the 6-pins brings the power from the CB to the microphone.
That is why you do not need a battery in this NOISE CANCELLING microphone, the DIGIMIKE

GREAT PERFORMANCE

The DIGIMIKE is on the market since some time now and the users love the quality. One of them told us that he used the DIGIMIKE in the car with the radio on a good volume. With maximum noise reduction the music from the song on the radio was gone, but some of the voice was still there !

This basicly describes what the microphone is doing: the sound from te surroundings, not being human voice, is filtered away. That makes that your voice is heard a lot better by the other stations listening to you.

EASY TO USE
The DIGIMIKE is user friendly. Unpack the micro and plug it in your President 6-Pin CB radio. Very old models may have a 6-Pin dynamic microphone and in that case the DIGIMIKE makes no sense.
On the top of micro you can change channels up or down and most important you can set the NRC level. NRC stands for Noise Reduction Circuit (same as NOISE CANCELLING). There are 5 levels , test with listeners wat they like best and you are ready to go.

FEATURES

Noise Reduction Microphone
• NRC = Noise Reduction Circuit
• 5 NRC Levels
• Up/Down Function
 Type:  Electret
• Connector: P6, President Wiring
• Packing: Box

You want to read the user manual first, check this link for DIGIMIKE USER MANUAL .

FINAL NOTE

It is the President DIGIMIKE, but if you have a CB from an other brand , that has a 6-Pin electret microphone and same wiring you can use the DIGIMIKE on that radio too.

PRESIDENT ELECTRET MICROPHONES
All new President mobile CB models use a 6-Pin Electret microphone. This means that there is a voltage on one of the pins. This voltage is used to power the hands free kit. So no need to make a power connection between the battery and the hands free kit. The power runs through the microphone cable.
This makes it an easy installation and more safe than with an extra power cord in the machine.

FROM I-MAX 2000 TO MAX OPTIMIZER

Image: Logo from Solarcon in the old days

SOLARCON ANTENNA RESEARCH
Long long time ago in the city of Holland Ohio in USA the Solarcon factory proudly introduced a new antenna the “I-MAX 2000“. This was the big brother of the Solarcon A99. In those days still known as Antron A-99 (Aka Atron A-99).

Photo: original carton for I-max 2000

I-MAX 2000
The CB and 10 Meter HAM people loved the new antenna and many were sold. One company did not like the name, this was the IMAX group of cinema’s.
Their lawyer wrote a letter to Solarcon and the wise people from Solarcon decided it was better to change the name to MAX 2000.

Photo: The new packing for MAX 2000

MAX 2000
Max 2000 is a wide band antenna. During the years the number of 10 meter users went down and it was more CB users that purchased this high end antenna. Many also added the the (I)MAX-GPK , a nice groundplane kit.

ANTENNA LENGTH OF (I)MAX 2000
The packing of MAX 2000 was designed based on the maximum dimensions of UPS cartons for easy and cheaper shipping. When UPS changed her ‘rules’, the carton was made a little shorter, but the antenna was still having the same length. Funny is that many people keep saying that the new model was shorter and that was the reason for a bad SWR. Sorry guys, the length never changed.

Photo: The packing of Max-Optimizer

MAX OPTIMIZER
The original IMAX-2000 was designed for 26 – 33.5 MHz. But now, because more CB operators were buying Max-2000 it was needed to make a MAX-2000 only for 27 MHz. That means a bit longer antenna length. The result is the brand new MAX OPTIMIZER.

Photo: Original specs from (I)MAX 2000

MAX-OPTIMIZER

So recently the MAX OPTIMIZER was introduced. Same box as MAX 2000, just a sticker on the top or bottom. The models MAX 2000 and MAX OPTIMIZER are nearly identical.
BUT the MAX OPTIMIZER has one more section, and that makes it a bit longer, approx 30 cm.

OPTIMIZER SECTION

Photo: The Optimizer section

If you are using an (I)MAX 2000 and want to modify it to a MAX OPTIMIZER you can purchase this extra section and install between the sections of your existing antenna.
The name of the product is OP-EXT , “optional extension”. The price will be around 50 – 60 euro.
Ask your local dealer for the OP-EXT and have better SWR on the regular CB band.

RM type KL703 DAMAGED

Using high power linear amplifiers can give good results in transmitting, but there are also big risks.
The worst that can happen is that you create interference to others.
That can be CB’ers , HAM’s or TV-Audio users.

Recently we received from a dealer a RM type KL703

Linear Amplfier from RM Italy, Type KL703

DAMAGED KL703

This amplifier is build by RM as nice piece of equipment.
But when handled without knowledge it will be damaged and break down.

PCB of KL703

From a distance it looks like a normal PCB, when we zoom in you will see the PCB tracks are damaged.

Damaged PCB tracks of KL703

Repairing such an item is not easy. Replacing a components is easy, but in such a case the damaged trakcs need to be re-soldered. This is costing a lot of time and money.

But there can also be damaged tracks that do not show damage yet. These can give damage in the future.

WHY DAMAGED
It is easy to damage a linear amplifier.
* Use too much voltage
* Use too much power
* Transmit for a too long time
* Lack of ventilation
* Cables too long or not enough mm2

  • In this case the amplifier was used on lower frequencies than it was designed for.
    On lower bands the gain of the amplifier increases very quickly and can cause this proble.
    Certainly when using high power.
  • Not many users realise this can and will happen.

    YOU ARE WARNED NOW , SO BE CAREFUL OUT THERE !!

CES 2023 – MESSAGE 6 – TRUCK NEWS

CES is all about new technologies. I mentioned already the many new personal car concepts. But there is also news about trucks for the present and the future.


PACCAR

One of the exhibiting companies is PACCAR. They make trucks under the brand names Kenworth, Peterbilt and European brand DAF.

Photo: he PACCAR booth, showing Kenworth, Peterbilt and DAF

Self driving is not only for private cars. One of the trucks shown at CES is also ‘self driving’. There is a lot of sensors, camera’s and radar on such a truck. I wonder or they still have a place to put on a CB antenna.

At some point there will be a person driving such an autonomous driving truck and we all want to talk to colleague’s.
But before there is autonomous driving we have to get used to driver assistance technologies, also for trucks.

EV TRUCKS

For the moment the biggest switch is to produce trucks that have no CO2 emissions. There are two options in the trucking industry. Paccar was showing an E-truck from Kenworth. For now this model has a range of approx. 250+ kilometers and a top speed of 110 km/hour.
More info about Kenworth EV truck T680E can be found on their website:

Photo: Kenworth EV truck model T680E

Driving an EV truck is one thing, but you also need chargers for trucks. The battery can store nearly 400 kW and can be charged with 150 kW charge rate. For charging you need chargers and Paccar is offering also EV charging stations.

Photo: Paccar EV-truck charging system

Paccar does not only produce fixed chargers. They also make a mobile EV charger. Can be used for trucks that need charging when no charger is at that spot. Or think about a hotel or parking garage that offers a ‘mobile’ charging service for private cars.
I would love to have this thing at home as a battery for my solar panels !!!!

H2 TRUCKS

Also from the brand Kenworth, they showed a ‘Fuel Cell Electric Vehicle’.
These types are also called ‘H2 hydrogen’ models . The range of this model is approx. 350 km.

Photo: Kenworth H2 Hydrogen truck

The hydrogen tank is placed after the drivers cabine. Let us hope these tanks are well protected and the used techniques make sure that they can not explode.

It is clear that the market for personal cars will change dramatically in the next 10 years. But also the truck market will have incredible changes.

The Hydrogen and EV trucks from Paccar are already available and driving on USA roads.

Take a look at what the truck industry has to offer already at this moment.

A FULL GROWN BATTERY -:)

There are many publications about the danger of Li-ion batteries that explode or cause a fire.
This week a friend showed me his iPhone. At that moment you realize the real danger of such a battery.

The battery pack had ‘grown’ but was not exploded yet.

If you find a battery like this be very careful, it can explode an do lots of harm.

Casing of iPhone was opened under pressure of growing battery pack.

DAF TRUCKS AT CES IN LAS VEGAS

One of the big truck brands in Europe is the Dutch brand DAF. Years ago the American company PACCAR purchased the DAF company. Paccar also owns famous USA truck brands like Kenworth and Peterbilt.

PACCAR is Paccar, Kenworth, Peterbilt and DAF

At CES, the Consumer Electronics Show in Las Vegas, Paccar showed some projects they are working on. Basically there are two main directions they go for now:


Medium Duty, Heavy Duty and Autnomous Trucks
  • 1. PRODUCING ZERO EMISSION TRUCKS

They work on solutions for the truck segments ‘medium duty’ and ‘heavy duty’. There are solutions already available or these will be available soon. At the convention they showed an electric garbage truck that had zero emission.

Electric Garbage Truck

But also for the heavy duty trucks they are developing zero emission solutions. It is interesting to see the number of cables and their size that are used to bring the power from the batteries in large boxes to the electric motor. Paccar calls their system the ’Paccar integrated Power Train’.

  • 2 RESEARCH TO AUTONOMIC DRIVING

Paccar does not yet believe in trucks without a driver. They do research in the State of Washington for full autonomous truck driving. They need to do this to get all the possible knowledge for driver supporting systems and potential autonomous driving for trucks.. Even if that will be used only on main roads and not in the cities or on company sites.

AUTONOMOUS DRIVING IN GENERAL

There is a lot of writing and talking about autonomous driving. But imagine a car or a truck in a city like Amsterdam with small streets and badly parked cars. But also the thousands of bikes and pedestrians. Many of these do not care too much about traffic lights. It is already difficult for a human to drive there without having an accident. For an autonomous car it is totally impossible.

So driver support systems are already available and will get better in the future. Driving a Tesla I personally experience that the systems gets better with each update. But full autonomous cars without a driver is a very long way to go.
