Icom released new 1.33 firmware on July 31 : USA 02 version linked here.
Changes in v1.32 firmware
Fixed distortion that sometimes occurred when receiving a signal in
certain situations (has our audio distortion issue been addressed ?).
- Improved parts of the speech function.
Changes in v1.33 firmware
Fixed an issue where the digital mode's audio is not output after
starting a memory scan with analog and digital modes in the memory
- Fixed an issue where the CI-V baud rate may not set properly when receiving a CI-V command when turning OFF the receiver.
Latest Firmware v1.33, the "audio distortion / harshness" returns to our ears ! : With v1.32 firmware
the audio distortion / harshness issues
to MY ears with 1.30/1.31/1.33 has been truly fixed. We strongly
recommend V1.32 if you desire the best audio from the receiver. Even
cleaner / sharper than what 1.20 did......excellent indeed
Icom..."thank you" ! Yes with the latest v1.33 firmware the nasty
distortion / harshness returned in our view. I will say
that it's has to be the cleanest and most pleasant sounding
communications receiver we have
EVER used with the 1.32 firmware installed, yes it's that good. Icom
now needs to fix what I call the "AGC Swamping" bug. See my
updated version 10.0 review for the updated information on all of these topics (added mode and NXDN information).
UPDATES : (Updated : Jul 31)
- After more time using it, the CS-R8600's (IC-R8600's programing software from Icom) "print function"
is near useless in our view as as it can't print entire channel information
on one page and wastes paper to total unreasonable limits ! We used
screen shots of the GUI "pre-print" screen (landscape) and just printed those .jpeg's (even if this was a
chore to make happen).
- "BUG REPORTS" have now been moved over to the BOTTOM of the review page.
Will continue to update these as required on the review page, but only
to cover samples with the new 1.32 / 1.33 firmware now (Last entry Jun 01).
- Version 1.01 "USB I/Q Package" for HDSDR
was released on May 31st. Now supports the Windows 10 Version 1803
(April 2018). Note : We have not tested the I/Q feature of the IC-R8600
(nor do we use Windows 10).
- Eric Cottrell reports that the Icom has released the IC-R8600 I/Q OUTPUT REFERENCE GUIDE.
- Simon Brown's “SDR Console” program for use with the Icom IC-R8600 I/Q output. Remember that “SDR Console” does NOT require a EXTIO.
- "Icom IC-7300" N9EWO Information : "Line Audio Output" : Added comments with our IC-7300 review in regards to the now tested "Line Output" at pin 12 of the 13 pin rear connector,
plus updated "Voice Synthesizer" information at this output (as well as
the built in SD card recorder).....yes it can indeed "voice stamp"
recordings...excellent. My apologies that I missed this important
feature in the original report (it's not set ON at default). See my
review for more information on this topic.
- Updated "SDRplay RSP1" Review : We have updated our SDRplay RSP1 review.
Includes updated SDR program ratings/suggestions. We placed "SDR
Console" at the bottom of the heap due to it's totally insane expiring
scheme (unacceptable in our view). Our issues with "SoDiRa" and the
EXTIO are no longer valid. Version 4.2 EXTIO works just fine with it.
Works the best with DSD+ in our latest findings. Also updated our DSD+
instructions/notes at the bottom of it's page. Remember this review is
with the original RSP1 (now discontinued). Model was replaced with the new RSP1A
which uses a 14 bit scheme, 0.5 PPM TXCO and added front end filtering
(not tested). A few typos have now been corrected in this updated review (sorry about that). (Updated : Jul 19)
UPDATE : Carl S. reports to us directly that his AR-DV10 sample
has these shortcomings : Flickering display, extremely low audio, low
sensitivity and yes the dreaded drift issue. Has not enjoyed 1 good
monitoring session with it. Strong "Caveat Emptor" at least for now. (Updated : Jul 25)
- Restored JRC NRD-301A and NRD-93 Reviews : In
the web page move back to angelfire, a few old / outdated pages were not
copied over from the old host (and will not make the move here).
However a number of readers wanted me to bring back the Japan Radio Co.
(JRC) NRD-301A and NRD-93 reviews. So we did just that and made a few minor updates in the process.
Mind you these reviews are not in any huge detail. Expensive
and very well made premium receivers, but we felt (and still do) that these and even the DSP JRC NRD-630
were overall disappointments to our ears , even more so when compared
to todays modern "direct sampling" SDR technology. (Jul 12)
- Sony ICF-2010 AC Adapters : Added AC Adapter information / photos and important links to the ICF-2010 / ICF-2001D section of the Sony Page.
There were 3 different included AC Adapters over it's 18 year lifespan
on the market (version sold in the USA). We breakdown the details /
model numbers / current ratings and other information. (Jun 24)
- Sony CRF-1 “Repair of a Slipping VFO” : Sony CRF-1 issue that is repairable. See the near bottom of the Sony Page for the new information added. Appears that this repair is not for the faint of heart ? (Jun 05)
- New "Icom IC-7610" HF Transceiver Issues ! : User reports with the Icom IC-7610's
two internal ADC Heat Sinks
that are or get loose or completely fall off with some samples. Even
a bigger nasty is that some samples are experiencing LCD
burn in issues (which is not a problem with the IC-7300 or IC-R8600).
See the link and "You Tube" videos below for more information.
The IC-7300 has one of these same ADC heat sinks. With the IC-7300 it
lays on the TOP, whereas with the IC-7610's are on the BOTTOM (upside
down). I do not believe the
IC-R8600 receiver has a heat sink on it's ADC. (Updated : Jun 04)
- Whistler's NEW TRX-100 and TRX-200 Scanners : Whistler has announced that they are in development of the TRX-100 (handheld) and TRX-200 (desktop/Mobile) scanners
which will feature an I/Q demodulator and A2DP Bluetooth Transceiver.
With the addition of the I/Q demodulator, the TRX-100 and TRX-200 are
to finally deal with weak signal conditions and Linear Simulcast
Modulations (LSM), an issue that has plagued scanners up to now. Like
the TRX-1 and TRX-2 will also include DMR and NXDN at no additional
cost. The TRX-100 and TRX-200 are scheduled to begin shipping in Q4
2018. (May 17)
Many replace the main 3 pot controls with
better quality ones (at around $ 10. to $ 15. for EACH control). In our
limited research near "drop in replacements" COULD be ? : PEC Brand (were Honeywell Clarostat RV4 Series), Both Linear Taper, 10 %, 2 Watt
. NOTE : We have not replaced these in our sample (at least not yet), nor have we acquired the parts to do so.
2 "Gain" Pots R9 and R20 : TWO RV4NAYSD251A (250 ohms)
1 "Phase" Pot R16 : ONE RV4NAYSD102A (1K ohms)
- AOR AR-DV1 Review :
Our "AOR AR-DV1" review is available here . Information
in our review that has NOT been covered anywhere else (up to now)
including the frequency display being off and totally unacceptable
audio quality for ANY broadcast listening. (Updated : Jun 20)
- Icom IC-7610 "Fan Operates in just Receive Only Use !" : The Icom IC-7610 "Direct Sampling" SDR HF Transceiver's receiver section draws around "3+ amps" of current just as with the
elder IC-7600 model did (via information as indicated
in the brochure). We of course had a gut feeling that the fan
would operate in just RECEIVE ONLY use ??
- "Universal Radio" has Moved to a New Location as of Monday October 16th, 2017.
Radio has moved its operations to a more efficient location here in the
Columbus, Ohio area where we can continue to serve our loyal customers.
This will be the fourth location change since Universal was founded in
1942. We look forward to many more years of serving the amateur and
short wave communities which Universal Radio has done for 75 years. The
new location is a 30-minute drive from the old Americana
