IC-7300 - Software Defined Radio

[VK3PF]

Hi all,

The first shipment of 10 units has arrived in Melbourne..... I am fortunate to have one of them on loan for a couple of weeks to prepare a review.

Regards,

Nice! - where will your review be published ?

LOL you will find that vk3pf is the editor of AR magazine, so join the dots

Hi Peter & Tim,

Yes, in Amateur Radio magazine will be the place. Given that we have a lead time of about a month and the radio has only just arrived, there is a VERY slim chance that it might appear in the May issue, but the June issue is more likely.

I must admit, it is slightly odd to see a transceiver go into screen saver mode (blank screen)... I have not seen that previously!

Cheers,

Peter VK3PF

I think that you will find some of the other screen based transceivers (Icom 756 and similar) have a screen saver mode. You usually put your call sign in it and scrolls across the screen.

Cheers, Mal VK3AZZ

Doh! - didn't even make the connection and here I am reading the GippsTech section in the latest copy !!! Where's a face palm emoji when you need it ?

My apologies for not seeing the bleeding obvious.

I'm keen to see your review Peter. I have already thought of a few items to sell off to fund the purchase of one of these rigs, just waiting to see some more reviews to convince me further.

Hello,

The 7300 certainly is getting some great reviews and even has a 4.9 out of 5 rating on eham after 60 reviews, unprecedented. http://www.eham.net/reviews/detail/12742

Now for the 7300S, a 10 watt version for $1300??

If Icom can also provide a transverter offset the 7300S would make an ideal IF for 144 and up transverters.

Next, to see if David VK3HZ can make a GPS xRef as well, it has a 41.344MHz crystal oscillator (X1201 on the main board) that has a reference voltage input, it may just be possible!!
There are 5 other crystal oscillators but they do not appear to be involved in frequency control.

73.

X1201 is definitely it. That unit is ICOM part CR-932 which is also the ref osc in the IC-7100.

The CR-932 is actually a Murata VC-TCXO part number TTS27VSC-A7, details of which can be found here...
