MVT7100 - Spare - Info purchase
 

Hiya,
Like you, I really rate the MVT7100, especially for the audio it produces on the AM mode for military aircraft.
I hadn't had one for a while and was pleased to come across one in very good nick on an auction site, the only drawback is that the print has started to rub off on the keyboard individual keys.
I would very much like info from the members of the site as to any dealers who are likely to be able to provide me with one.
I would be very happy to get contact with anyone who may have a dead/damaged set that I could rob a keyboard from.
Thanks

Hi Mike in Chesterfield..

I have a Yupiteru MVT7100 in good condition (functions OK, body good and clean) apart from loose battery cover, and intermittent loss of reception due to dodgy aerial internal connection I believe. I have modified Key Lock button to operate backlight on/off.

I am prepared to offer it to you at a reasonable price if you are interested, its better than 'spares or repair' if not 100% perfect. If so please PM me or reply here and we can discuss.

Thanx, Goldox.

'goldox',

if Mike decides not to take you up on your offer then I may be interested. Thanks.

One word of warning. Unless goldox can be certain that it is an antenna problem causing intermittent loss of reception I would urge caution. An antenna problem should be easy to fix but if it is a dry joint on the main circuit board then that could be far more difficult to repair. Whichever, to fix it one should be skilled enough to undertake the job - soldering, etc.

Following on from HDs comments:
I do not have the expertise to diagnose the exact reason for intermittent loss of reception, however I do know that when it happens, slight pressure on the base of the aerial fixes it. I tend to use a BNC connected to external aerial so there is no movement of the set thus it behaves perfectly. It seems to happen when the long straight aerial is connected and it puts a bit of sideways pressure on the connector. Better brains than I will probably diagnose this...


I did manage to open up the set to modify the circuitry to use the lock button as a backlight on/off, which involved a little soldering and adding wires etc, amazingly it worked even though I am ham fisted. I did run some solder onto aerial internal connector which seemed to fix the reception for a while, but it probably worked loose again.


As for the set it is very clean and no wear on keyboard which is what Mike was asking for originally. Apart from the intermittent reception problem it is excellent. Hope this is helpful.
