Bandercom Modified MVT-9000 Models

Maybe the best handheld scanner? It is in my opinion!
I like this scanner very much! Sensitivity is great and the alpha-tags are nice. The band scope function with up to a 1.6MHz sweep is great if you search/monitor new frequencies. The Marker function is also useful for sweeping around the display and immediately tune the marked frequency. And it's the only real-time band scope with active audio in any scanner!

The first new modification for 1999 is a discriminator output for the MVT-9000!

This baseband signal is brought up to the top panel of the radio where it is connected to a 2.8 mm monaural jack. Get a cable and you're ready to decode digital and sub-audible signals using various decoder boxes or computer software!

When ordering your MVT-9000, simply order the DO-9000 option.

Bandercom Modifications

Ask anyone who has used the MVT-9000 and they'll tell you what a great radio it is and how it does so much, so well. Well, believe it or not, Bandercom has managed to make it even better!

Bandercom now offers the 'M' models for your listening pleasure! Read on to find out more...

Bandercom MVT-9000 M

This was the first 'M' model and offered two significant improvements:

10.8 Mhz intermodulation inteference is reduced 40 - 70%!

This modification reduces the strength of intermodulation frequencies generated when a strongly received frequency mixes with the internal 10.8 Mhz oscillator. This also serves to further reduce the number of birdie frequencies!

Scan and search speed is increased 35+%!

Unfortunately, this particular model is no longer sold by Bandercom but you might see it on the used market!

MVT-9000 M2	MVT-9000 M3
The M2 model is simply the original M model with a handy addition! A green LED was added to the top panel which serves to give the status of the radio squelch and battery saver circuits. When the squelch breaks to receive a signal, the LED lights continuously. If the power saver engages (after receiving no signal for 5 seconds), the LED flashes to indicate the power saver is active.	The M3 model is the latest and greatest! It incorporates the changes made in the M2 model as well as enabling the PRESET feature. The MVT-9000 was originally intended to be sold in Japan and Europe. Models sold in Japan had a PRESET feature which allowed the radio to automatically select the receive mode and step size based on the frequency that was entered. Radios that were intended for sale outside of Japan had this PRESET feature disabled. Luckily, we found out how to re-enable this feature and can now make it available for our customers!
The latest updates (5/99) to ship are the M2.4 and M3.4 models which have reduced 10.8 Mhz intermodulation inteference by 70 - 95% (which also reducies the number of birdies), and the scan and search speed has been increased by 42%!. Modification have same effect to MVT-9000Mk II model. Unfortunately Mk II model have that same basic problem as regular MVT-9000. Latest Mod version is M2.5 and M3.5 Its in MVT-9000mk2 model, its actually take that irrating 10.8Mhz intermod away. level where that intermod appearing is now above 80dbµV antenna signal. Also Colour of RX-led can be select between green, red, yellow and amber. (default colour is green, so please remember mentioned your led colour when order) Check difference's here

MVT-9000 Specifications

MVT-9000 Update

Yupiteru has increased internal shielding after May 1998 to gain CE certification for sale in Europe. This effects models with serial numbers 708xxxxx and up.

The result of this shielding is to reduce reception interference from minute signals generated by the radio itself. This means less birdies and fewer annoyances when scanning and searching!

Attention 'Yupi' Owners

Are you a proud Yupi owner and just can't get enough? Perhaps you have a question? If so, feel free to contact Mika who heads the Technical department at Bandercom and performs the modifications to these great radios! It's doubtful that anyone knows more about the MVT-9000 than Mika...except maybe those who designed it!

M3 Measurements
The following measurements were taken on a MVT-9000 M3 (series 708xxxxx) by the Finnish scanner magazine Skanneri

300Mhz	90µV
460Mhz	230µV

Leakage radiation is a meausure of the RF energy being generated or radiated by the device under test. In order to be approved for sale, the measurements of RF energy at various frequencies must be below preset limits determined by the Finnish government (to ensure this device will not interfere with the operation of other electronic devices). If the measurements are not below these limits, then this device can not be offered for sale. And the less the radiation, the less problems there will be with birdies and intermodulation inteference.
