Вот отзыв от PA1TNO с ЕНАМ.НЕТ:
I use the IC-910H most of the time for satellite communication and weak signal reception.
I also use a Kenwood TS-2000X, so I did a side by side comparison.
The sensitivity on both rigs is about the same, however the TS-2000 seems a little better in weak signal detection.
The IC-910H has CTCSS, but encoding and decoding at the same time.
CTCSS cannot be used independent from each other, i.e. RX 71,9 Hz, TX 88,5 Hz. (not without modification).
The radio has no DCS,no DTMF and memory channels cannot be locked out to be skipped.
The RIT control range is only +/-1KHz on SSB/CW and +/-5KHz on FM, not enough for convenient use.
I installed the UX-910 1200MHz unit, but it's not possible to work in NBFM on 1200MHz...
Don't loose the manual, because this radio has a very cryptic menu system.
No alpha tags.. so you need to write down your assigned memory channels on good ol' paper.
The included 13,8V power cable is the shortest I've ever seen.
TX on 70 cm produced a substantial amount of spectral impurity, that affects 2m band reception.
The IC-910H has only LF DSP, it helps to fight the noise, but not as effective as the IF DSP on the TS-2000.
This radio totally lacks user friendliness, and it shows when using it as a satellite only rig.
For example, adjusting your uplink frequency, requires you to switch between the main (downlink) and SUB uplink band, than adjust your uplink, than switch on the downlink band again.....ad infinitum.
Doppler compensation by computer helps a great deal, but I prefer the flexibility of manual control.
The IC-910H doesn't have "real" continuous SUB band tuning, like the TS-2000, in my opinion a BIG shortcoming.
Are there any goodies? well yes, the IC-910H has more punch on 70cm band, 75 watts compared to 50 watts from the TS-2000.
It doesn't suffer from the annoying S9 birdie the TS-2000 has on 436.800MHz that wipes out the SO-50 and AO-27 satellites.
When equipped with the CR-293 high stability crystal unit (like I did) the frequency remains rock solid.
My conclusion,
Would I buy an IC-910H again?
Probably not.
У TS2000X ДСП по ПЧ, включенная в петлю АРУ. У 910 дсп по НЧ. Толку с такого ДСП практически никакого :blev: Остальное расписано голландцем-"Куплю ли я 910 снова? Наверное нет"
...For example, adjusting your uplink frequency, requires you to switch between the main (downlink) and SUB uplink band, than adjust your uplink, than switch on the downlink band again.....ad infinitum....
А зачем таким изощренным способом. Все намного проще на самом деле.
RTFM!
Лучше попытаться найти итоги соревнованийЦитата:

и проанализировать - какую аппаратуру используют победители.
В отчетах обычно просят указать тип аппарата и антенн.
А с таким подходом - вы узнаете лишь мнение большинства.

Зачем плодить одинаковые темы, есть тема 910, где Вам все растолковали. Тема закрыта
