Icom IC-905 144-10 GHz Transceiver announced!
« on: August 23, 2022, 06:49:38 AM »

New from Icom  https://www.youtube.com/watch?v=kzGQWmTKNzc

Has 144, 430, 1200, 2400, 5600 MHz radio. and 10 GHz with an optional module.  Introduced at Tokyo Hamfair this month, and the remote RF unit resembles the one shown at Hamvention in May.

Supports all modes, even FM-ATV.  Its appearance is similar to the portable IC-705.

WOW!

Yep, Icom seems to be in the Amazing Business. :)

Taking their SHF Concept / Prototype...  https://www.eham.net/community/smf/index.php/topic,136177.msg1261304.html#msg1261304
And combining it with the guts of / QRP-version of the '9700....and, with the control-head/user-interface of the '705! 

Yep, that makes for an amazing radio!  But, like the Ginsu Knives, there's even more!

Heck, even if it's close to $3k....it's still a lot of radio for the money!  :)


And, adding tower-top external PA's, of say ~ 100 - 200 watts for 2m and 70cm, and maybe even 100 watts for 23cm (yes, you'd need more electrical power and need to run power cabling for them), and you'd have a killer vhf/uhf terrestrial station!

Heck, if you added a KW PA's (probably a 65v LDMOS design) for 2m and 70cm at the antenna array, and/or a few hundred watts at the dish, on 23cm....you'd have a rather easy-to-put-put-together moonbounce station!  :)


Together with the pre-distortion announcement regarding the new PW-2 (PW-2 & 7610)?
Icom certainly isn't resting on it's laurels!  :)

https://www.eham.net/community/smf/index.php/topic,137014.msg1271865.html#msg1271865
Wyn,
I was thinking a similar thing!  Maybe, after 10 years of waiting (and hoping....and speculating) we will be getting adaptive digital pre-distortion in off-the-shelf / mass-produced ham gear?  :)

The u tube piece references its 'pre distortion' use specifically in conjunction with the Icom 7610, I wonder if that has any inference in relation to wider compatibility on that front.

It's a little unclear from the video whether the PW-2 has this pre-distortion firmware/software and will feed-back the corrective info to the 7610 (via its LAN connection, etc.?) and have the 7610's transmit DSP make the instant corrections, as directed by the pre-distortion software in the PW-2?  Seems a bit convoluted, but that's what they seem to be implying?  with the PW-2 brochure stating: "Super low-distortion output with superior IMD (Intermodulation Distortion)"

Will current 7610's in the field need firmware upgrades (probably yes)?

Or, are they inadvertently debuting (or paralleling debuting?) a new feature of the 7610 (with new firmware/software?), and like most new SS ham amps, the PW-2 has an internal RF-sampler/coupler that the connected radio's pre-distortion system will sample....and the 7610 will now have pre-distortion built-in?   {are using the second-receiver in the 7610, and during transmit only feeding its input via a sampled output from the PW-2?  (and then using new firmware/software in the 7610 to preform the pre-distortion?) as Glenn W9IQ mentioned months ago, during transmit the DSP processor isn't doing too much, and could certainly be used to do pre-distortion, yes?}

And, another video from Dayton...mentioning the software isn't done, yet....maybe they were still working on the pre-distortion software at that time (May 2022)...

https://www.youtube.com/watch?v=Z683LRiUSl4

Or, is Icom incorporating some newer / more modern version of Texas Instruments DPD devices (or other such devices) into their PW-2, and it works as-is?  (seems unlikely)
https://www.ti.com/litv/pdf/slwt017



What does seem clear is that wherever the pre-distortion is, however it is implemented, this is going-to-be a game changer! 

Remember, Icom made a clear statement with their debut of the '7300 (and 9700, 7610, etc), that they are not just looking to advertise some "great rec numbers", but rather are pushing both what is really needed and what can be done at certain price points (especially since the '7300's transmitter, wasn't that bad....and in comparison to much of its contemporaries, it was very good!)...

And, along with Icom's other new debuts, like the new IC-905 with 2m, 70cm, 23cm, as well as 2400mhz, 5600mhz bands (and 10ghz with additional/optional external xverter module)...

https://www.youtube.com/watch?v=xRPwFFimg8Q

It looks like Icom isn't resting on their laurels!  :)   
And, unlike Yaesu's marketing by their numbers, Icom seems to be on the forefront of what really matters....I'm not knocking 100db+ rec IMD radios, but Icom (and Apache Labs) seem to be the only one addressing our poor transmitters!  :)


I look forward to more info!  (anyone that has it, please pass it on here)

Ed, thanks for IC-905 news, here!

New and innovative, it'll be pricey, at first anyway, as all new releases are. Icom is currently the leader in new technology. They'll sell a ton of them.

One ad on Twitter shows they are going to debut at 9,999 Euros.

 They are missing a band on it and it's too expensive

It's missing several:  The 222, 915, and 3400 MHz bands.  None of those bands are available outside of Region 2, and 3400 MHz is going away in the US in the next few years.

222mhz and 902mhz are both available in Somalia (a region 1 country), and maybe in other countries as well.  I would bet that countries outside the US will still have access to 3.4ghz after the US hams lose it.

Will the 10 ghz transverter show 10 ghz readout?

I see it will show 10 ghz readout.
