This is the third HF transceiver that I bought. I was looking for a while for
|
|
an alternative to the FT-891, because I wanted something leightweight for my
|
|
little hiking tours.

## Low quality mic?
|
|
|
|
It's like many plastic mics on other radios, it definitly feels a bit “cheap” and
|
|
it was the first (and only; until now) thing that broke. I haven't noticed the broken
|
|
mic until I tried to call CQ in the mountains and I fixed it on the same day. I haven't
|
|
been out since then...
|
|
|
|
I bought a Laravel mic from Amazon and I already got a spare in-ear plugs from Sennheiser
|
|
which I combined with the [adapters from Robert W2ENY](https://w2eny.com/tx500/) (including
|
|
a hand-held push-to-talk button adapter (like the Heil HS-2 but smaller).
|
|
|
|
This is pleasing to use and you got the sound directly in-ear.

Since someone asked on a mailing list to verify his measurements
|
|
and I had my tinySA in reach I also created these measurements and
|
|
I do not want to hide them :)
|
|
|
|
As always, take these with a grain of salt!
