A question about anytone

Postby PE2CH » Thu 3 Aug 2017, 20:28

Hi,

I have an Anytone AT-5189 transceiver for 70MHz. According to the manual, this would have a 60 W transmission power. Is that seriously correct? I can't believe it, it's a small mobile transceiver.
However, it's works better than a Wouxun radio from China :D

As an antenna, I have a Nevada AT5189A 1/4 wave on magnet mount. The antenna is on a alu plate
of 50cm x 50cm in the living room near the window.
I live in the city in an apartment on the 13th floor. No ideal situation, but it works.

Hello Charles,

All googles refer to 5/10/25W output for the AT-5189.
In Finland it is sold for the free-time RHA-68 channels
with max. 25W, but that is the permit limit. Designed
for max. these PA's can run up to 70% efficiency, but
if higher power units are run at lower output at the
same battery voltage, then efficiency drops radically.
Therefore most probably these rigs are 25W units.

In case you suspect Es-skip to Finland: the OH-channels
are 70262.5 / 70275.0 / 70287.5 kHz on FM (F3E). Don't
expect much activity there unless you make noise yourself.

It's correct that all googles refer to 5/10/25W output for the AT-5189. Then it almost has to be a misprint in the manual. You can also see that in the online manual.
Thanks for your post about this.

Hello Charles,

It may often be the art of marketing. I do not know if the AT-5189
is a one-band unit per item, but it is strange that power output is
claimed as one constant series for 4 different frequency ranges. It
could be that 60 watts is for the lowest frequency, but with good design
it could be on each range, just that there may be a limitation on the
licensing side, and e.g ALC has to be set to force certain frequencies
in most countries (at least for RHA-68) to a certain maximum output.

On a competitive market it is dangerous to claim 60 watts that can be
verified with a 5 minute measurement as untrue, but with a foggy spec
write-up one can say: " Yes, but it means....[the lowest frequency] "

Antenna manufacturers often claim excessive gains in order to sell
on a very competitive market. It takes many hours to set up a reliable
measurement to prove it wrong, and one could accuse the measurement
as well. However, with today's antenna simulators, even claimed decibels
have come within physically possible limits, but still there are marketing
games with dBi, dBd and ground gain inclusive listings.

Cheers/73, "Zaba" OH1ZAA

P.S. There may be a potentiometer for ALC inside the rig that may allow
you to tune the output power up to 60W, but it may void your warranty.
On the other hand, according to the manual you are entitled to try...

Thank you for your comprehensive clear explanation.
This type/model Anytone is (or was?) available for five different frequency bands, always under the same type number. 2x HF, 2x VHF and 1x UHF version. I had to pay close attention when ordering this rig. It's was a webshopping order at a store in the UK.

In any case, my question was answered as well. Thanks for that!
Of course, I'm happy with this transceiver for the 4M band.
