UN8GC IC-7300 (U.S. version) modification

Initial idea: EX8MLT and EX9T. Realization: UN8GC




MOD IC7300 record received QSO

Has anyone come up with a MOD in order to record received QSO and transmit it back to the person you are in QSO with via changes to the record features in the IC7300?

ROB SHERWOOD TEST: ICOM IC-7300
Here are the test files from Rob Sherwood.

BONUS: In December of 2016, Rob used the TS-7300 in the ARRL 160m CW Contest and was quite pleased with its On-The-Air performance.

His review of the IC-7300 under contest conditions is below the downloads.

USING THE ICOM IC-7300 IN THE ARRL 160m CW CONTEST

I really enjoyed using the IC-7300 during this weekend’s ARRL 160-meter CW contest.  320 Qs, 55K points, a little under last year’s 63K points (all search and pounce).  No fault of the radio. 
I have zero complaints about using it in a CW contest.   While I wish the Bandscope / waterfall display had more options, the Bandscope did the job very well.  It needs an option to make it taller vertically in some mode and leave out the waterfall.  It could also use a 5 dB / division scaling since few stations ever go near full scale.

I hope Icom fixes the transmitter’s “key-up tail” one of these days, but my Alpha 89 or Acom 1000 won’t un-key until all RF is gone so they have no problem with this, but that isn’t the way to solve the problem.  Users may have problems with other types of amplifiers that don’t have this feature.

Icom IC-7300 review

Icom IC-7300 review

Icom IC-7300 is the first direct sampling SDR (software defined radio) available from one of the "big three" japanese manufacturers. This helps it bring a whole new level of performance at an accesible price point, a much more flexible configuration and a set of features only seen in top-of-the line equipment. Real-time panadapter or fully customizable filters are just the tip of the iceberg.

Sure, amateur equipment has been using for a long time various levels of digital signal processing (DSP), but usually this was done in the last part of the receive chain, where it mostly impacted audio quality and not receiver performance. Moving to a direct-sampling SDR architecture means the signal coming from the antenna is directly transposed to the digital domain and instead of all the previously familiar receiver stages (such as mixers, filters, demodulators etc) we are using mathematical formulas applied to the data stream. The advantage of this approach is it eliminates all problems related to real-world hardware receivers (noise, distorsion, losses, imperfections, limitations etc) and opens up a new world on how you can use or visualize RF signals. Goodbye unwanted mixing products, AGC non-linearity, IF chain IMD or filter blow-by. You want a 200Hz to 2250Hz SSB filter ? Just go into the menu, customize it to that value and see how that carrier at 2260Hz simply doesn't get trough; yes, filter width and shape is just a matter of settings, leaving it all to mathematics to carry it out. Basically, the only part that limits the receiver performance is the Analog-Digital Converter (ADC) that samples the RF signal, and those are already very good.

Here`s a quick and basic "how to" use the 7300's built in SWR graphing meter.
I think it was an oversight in the manual? Anyway a picture is worth 900 words [-GST] Pretty cool feature. I can imagine all around the world there's going to be 13 short carriers across the spectrum.
Just make sure you turn your power right down to say 5watts for starters. [FYI you dont have to put the radio in AM or FM to get a carrier]
