Icoms sdr based IC-7300 looks promising

Euro Version will have 4m ...or OIRT as we call it ;-)

this is the most appealing offering by one of the big 3 in a long time


I'm thinking.. wait a couple of years and pick up a 2nd hand one at a knock down price like I did with the amazing IC-7000

Yes it does - the 4m is very appealing.

Lots of boys also using the Yaesu 991 - http://www.hamradio.co.uk/amateur-radio ... d-5621.php for vhf/uhf work though no 4m tx. If you get one make sure it's "opened-up" - even so not sure if the rx coverage will support 4m/OIRT.

Lynchy is talking about a retail price of below a grand: http://www.hamradio.co.uk/amateur-radio ... d-6016.php

Hmm haha... or did you call them for a quote ? I think anything around a grand is about the right price...I guess :roll:

Am I missing the joke? Did you click the link? - "Many orders already taken so get in quick to grab your place! Estimated price of UNDER £1000. To get yourself on the reserve list and place a deposit of only £50."

It's all fun and games until someone loses a nut as the squirrels say.

Well, the joke could be on you, Stuart. By "under £1000", that probably means £999.99. Or could that be £9.99?

Why would anybody want to put a deposit on something when they don't know the price? Madness!

The joke may well be on me JF as I'm not sure where the punch line is.

Anyway the price is now confirmed at £1049.95 - no doubt the £ falling against dollar has had an impact - http://www.hamradio.co.uk/amateur-radio ... d-6016.php

Why would you put a deposit down? To secure one of the first deliveries - this will be a very popular unit. The guidance price was within 5% of the actual retail price so nobody should be getting any palpitations.

So there we have it! £1049.95 is not less than £1000. Say no more!

yes, but is 5% more going to change anyone's mind?

Unlikely. It wouldn't change mine. It's just madness gambling with an unknown price.

A good point in that thread about having to deal with first run design bugs too.

I absolutely love my IC7000, so I would expect the IC7300 to be a keeper too.

"Gambling with an unknown price" - lol de lol. The guestimated price was very close - and for once the dollar price is not the pound price. Buying in-country is the cheaper option.

"is this about the right price?" = seems lots of boys quite excited about this rig with its 4m coverage and sdr architecture. I would say it makes the ELAD FDM-Duo overpriced at £800.

"first run design bugs too. " - Ah ha - a sensible comment! The reason I would hold off a few months to see what the actual feedback from users is.

But there has been a firmware update recently in Japan apparently...

It's actually the same price as what they are going for in the US ($1495)...so we are not being ripped off this time it seems

Looks an interesting starter HF rig - especially with the 4m. Also ideal for portable use with its relatively small form factor.

Shame there is no dual-watch facility but you can't get it all for a grand!

from the Ic-7300 list
"

Folks,

I wonder if anyone else has noticed aliasing products from local
FM stations in the BC band 88-108MHz.
A fried of mine with a 7300 living in Munich,has compiled the following list (frequencies in MHz):

Aliasing Frequ. S-Meter-Reading Station true Frequency.
30,335 8 BR 1 93,7
30,735 9 Gong 96,3
31,640 9 Energy 93,3
32,735 3 Horeb 92,4
34,535 7 BR 2 89,5
35,035 8 2Day 89,0
35,335 3 BR 2 89,5
35,635 6 BR 2 89,5

The spectra are about 100kHz wide the signal maximum is about 10kHz wide.
It's obvious that the the FM signals are folded back by the half of the ADC's sampling
frequency,i.e 124.033 / 2 = 62.0165 MHz,but there seem to be also other mixing
mechanisms,e.g. station BR2 is mirrored three times.
Does anybody *know* if the 70MHz band is covered by undersampling or by frequency convsersion?
