I believe all 25 were pre-sold.

Sorry yes, from Rex. Odd he usually writes his name and callsign. I didn’t notice as I knew it was from him and written in his style.VK4GHZ wrote: Was this from Rex VK7MO?

VK5GF and I and 7HH only ones on anyway so my $350 IC910A fromTokyo ham fair is all that mode is worth.
APRS tells me more about 2M prop than WSPR
As for good luck
I work my backside off in middle of night fixing tv stations because we cant find any new chums to take on the work load.
50 years this July BOCP #7 and still working at 73YO.
The radio is one months pay, so be it.

Same reason I just bought an 6 year old 86GTS..with 4300 km on the odometer from a mate and driving it 2000k to Dubbo nationals on Saturday
if its a bummer like the 86GT, Cost $35000 bought for $20K,
we will see them under $2000 like the ill-fated FTDX3000 and 1200s and the crap 9981 991A..asss fell out of resale...
Its only money or a good set of golf clubs..
You cant take it with you old timer..
cheers.
Hi Adam,
Good thought…but the only solution I believe Icom will accept is one in which the frequency tuning of the internal master oscillator remains under the control of the FPGA.
This dictates a 10 MHz external reference, as the FPGA code was written to process a 10 MHz signal and apply the correct control voltage to the internal 49.152 MHz VCXO.
Replacement of the internal VCXO with an external lash-up is out of the question.
The phase noise performance of a direct-sampling/DUC SDR is critically dependent on the quality of the ADC/DAC clock oscillator, the clock distribution circuitry and the cleanliness of the clock power source.
Board layout is also a critical factor in this area.
Any major change would require a complete redesign of the ADC, DAC and clock areas of the main board.
I am hoping that Icom will replace the existing “rough check” comparison scheme with a PLL coded in FPGA firmware.
The PLL loop filter will need to have a cutoff frequency sufficiently low to minimise the impact of phase noise in the applied external reference signal.
Sorry, I am not in a position to distribute my copy of the service manual.
It was furnished to me in confidence.

No PTT per band on any of its ACC sockets either !

Improvements include;
Improved accuracy of the reference frequency automatic adjustment function-
Fixed a defect on the DR screen display-
Eliminated an interruption in the reception sound that occurs when switching the IF filter in DV mode
-Other minor corrections.
