1、Yupiteru MVT-7100 Owners Guide Rich Wells - N2MCA Introduction In an effort to better understand the operation of the Yupiteru MVT-7100, and to offer a valuable resource to other people who may be using these wonderful radios, I wrote this owners guide. It does not hurt that the originally supplied

2、manual that comes with the radio is rather poor. Like many translations from the original Japanese, the grammar leaves much to be desired. And, on the whole, the organization of the topics is not helpful in gaining a useful understanding of the radio and how all the pieces interrelate. This guide go

3、es through the operation of the MVT-7100 in a step-by-step process starting with the basics and builds up to the operation of the more advanced features. While Ive never had the pleasure of playing with the MVT-7200, most of what appears here should apply to it. Where there are differences that I kn

4、ow of between these two radios, I have pointed them out as best I could. Feel free to make copies of this document and distribute as you see beneficial to the radio monitoring hobby as long as it is done FREE of charge. I simply ask that this information be kept intact. A lot of hard work and effort

5、 has gone into the writing of this guide. I would appreciate it if every effort is made to keep this document whole with me as the original author. If you would like to share your thoughts about this owners guide, have suggestions for its improvement or have further questions, feel free to send me e

40、passed. Other Features AM Antenna To aid in the reception of medium wave (540-1710kHz) broadcasts, the MVT-7200 is equipped with an internal ferrite bar antenna that is used in lieu of the stock antenna for this band. The MVT-7100 must use the antenna attached to the BNC connector for medium wave ba

41、nd received. Attenuator If the radio is used in an area where excessively strong signals are active, it may be necessary to reduce their strength to ensure that the radio receiver functions properly. The Attenuator is used to reduce the strength of signals entering into the receiver. Signals that en

42、ter the radio and are too powerful for it to handle, may result in various forms of interference. Such signals may affect frequencies to either side or can even desensitise the receiver so that it may not be able to receive signals it normally can. To enable the Attenuator 1. Press FUNC + ATT 2. The

43、 ATT indicator appears To disable the Attenuator 1. Press FUNC + ATT 2. The ATT indicator disappears The VFO has its own attenuator setting as well as each memory channel. After a search band search operation is started, the Attenuator can be enabled or disabled as is deemed necessary. Battery Saver

44、 To extend the operating time of the radio, the Battery Saver feature is used. Not only can this feature be enabled or disabled upon request, the amount of time the saver circuitry is active can be selected. Three of the numeric keys are used to specify the battery saver level 1 = sleep for 0.3 seco

45、nds out of every 0.6 seconds 2 = sleep for 0.9 seconds out of every 1.2 seconds 3 = sleep for 1.5 seconds out of every 1.8 seconds To enable the Battery Saver 1. Press 1, 2 or 3 2. Press FUNC + SAVE 3. SAVE appears on the LCD with 1, 2 or 3 NOTE: If step #1 is skipped, a value of 1 is assumed To dis

46、able the Battery Saver 1. Press FUNC + SAVE 2. SAVE disappears The Battery Saver is only effective when used in VFO or Memory modes. If no transmission is detected on the displayed frequency within five seconds, the Battery Saver is engaged. Once engaged, the Battery Saver puts the radio “to sleep”

47、for a period of time, then “wakes up” briefly to check for an active transmission. The amount of time the radio spends “sleeping” can be selected. While the radio is “asleep”, power usage is lowered thus saving battery power. The longer the sleep time, the more power is saved and the longer the batt

48、eries will last. NOTE : Starting a search or scan turns off the battery saver. Beep The MVT-7100 sounds a beep tone each time a key is pressed. This helps to provide audible feedback during radio operations. Shipped from the factory, the beep tone is enabled which can be verified by the presence of

49、the BEEP indicator. For more discreet operations, it may be necessary to disable this feature. To disable the beep tone 1. Press FUNC2 + BEEP 2. The BEEP indicator disappears To enable the beep tone 1. Press FUNC2 + BEEP 2. The BEEP indicator appears Delay During a scan or search operation, after a transmission ends, there will be a two second delay before the scan/search is resumed. This delay allows for a response to be heard. To in
