Scanner comparison MVT7100 , XLT80, R10

MVT was my first radio of this type taken one and half years ago

MVT seems to be a good scanner that is a radio wise system ( ie you start the radio and it shows your last choice) easy to learn easy to use and very nice to operate . Good also to use it as a SW radio with good sensitivity and numerous memories but on MW and LW it requires external antenna, otherwise it can only listen to local (powerhouse) signals .Also good audio in both cases ( headphones and internal speaker ) with abt 8 hours of continuous operation when used as radio in low to normal volumes .

Its battery save mode has 3 positions with a scan point every 1, 2 and 3 secs. Every memory except the freq , mode, and attenuation still contains the step mode (??) used when it as programmed.

Scan programs are immediately modified once step is changed

The receiver is easily overloaded once you use external wire antenna as I , with overloads occur on he 165 û180 mHz part from some very strong SW stations. Also during the nights with power house signals on the SW bands and with its telescoping antenna in full size some signals still can pass this bands . From birdies size , it has numerous across all bands . Some of them are near to S9+40 even on att mode ( eg 269.7MHZ )

Its pass freqs do not occupy the memories . Only one priority channel only.

During save mode the scanner picks up a signal trace tone with a rate of 1 2 3 secs

I prefer it from XLT in general

It is the winner in scanning speed

Update : MVT has three mysterious drawbacks:

-Often the radio can stuck in a frequency so that it cant change memories , obeyt to button orders etc .I can still happen if adio is iwitched off and on again .The thing is solved easily after you press C/AC for several seconds!

-During battery change and immediate switch on (?) , RESET can be made by itself Thisis a toital damage as everything can be lost: memories ,scan ranges , deleted freqs etc. This is the most danfgeous sistuiation and you need to reprogram it . UNfortuately this radio is has not PC interface for fastter reporgrammiing. Although it is qite easy to redo the work the stiff butons mke the job harder...

-For unknwon reason it happened once to not only remove everything but also block itself sevral bands. Bands were on 260-3xx (unmeasured) 830-860 914-959MHZ - two and otehr smaller . Forunately a simple RESET corected that.

I bought this scanner from the local market for a friend , as a gift. I kept it in order to preprogram it and give to him later. The seller told me that this is the latest model Uniden made

Very simple scanner too costly regarding to MVT in specs and operation. I waited something more from it namely at last two scanning steps ( say 5 and 10 kHz for VHF , 12.5 and 25 kHz for UHF)other wise it is very annoying to wait scanning esp in the 800 + band . It is good for persons not requiring anything but listening to pre-determined stations

Mysteriously in contrast to what is stated in the specs the 800 + band with FM mode seems to use a AM type mode û capable also to listen to FM TV subcarriers found on the lower end of this band , and some NBFM signals sich as from remote telephones were not listen-able but only as æemptyÆ carries ( better discriminator than from others)

Very few birds have been found

As less sensitive than other models it is not efected with overloads when used it with external wire antennas.

What I liked much in it is the usage of a STEREO heads socket not used in other models.

This is the æradioö for e friend of me after he has seem mine. IN general this is s very complex having the philosophy and the design of a cellular phone and required a big learning curve in order to use it and program it as I wlways must to consult the op guide.

Full menu driven , with the philosophy of the latest models of ICOM (als for the R 75 SW receiver ).

From performance it exceeded the audio of MVT ( so : higher bandpass on SW bands and better audio amplifier ) and the sensitivity of MVT esp on the VHF /UHF bands when both radios used in parallel . I did not like however the way of memory programing and band change as it required to use the FUNC button at the left side of the speaker

Some of the nicest features were the total mute when there was no signal as well as the auto memory write search

It s attack time while in save mode was abt 3 secs

IN general : R10 is the winner in features and functionality

What I did not like: Its headphone socket was too bad that very easily the head pug is pulled out à..

Comparison between receivers:

I m sorry but parallel tesing between R10 and MVT was nearly imposible as after the T splitter the wires used behaved as antennas that effected reception too much giving more than 3 æbarsÆ of signal in certain cases and in some QSOs different users produced different signals in each model ( say : user 1 gave higher for MVT user 2 gave lower for MVT)

As in general :

SW : MVT gains in reception diring the most bands. Its S meter is more sensitive than R10

2 m : R 10 gains better

400 mHz : again R10 better

UHF / TV : MVT was little better
