IC-7100 User Evalutation and Full Test Report plus IC-7100/IC-7000 Feature Comparison by VA7OJ, Adam. (! see link +below!) – See the Video demo by GØTAN Engineering staf at ML&S Ltd UK (link +below) - I think that hams using D-STAR will find it a nice addition to their base or mobile setups for DV (digital-voice & data) mode on the 28MHz, 50MHz and VHF UHF bands. (!… danger mobile radio: keeping your eyes on the road!) – See the pictures, video and more below.
The IC-7100 display contrast ratio is also quite nice. I wish it had a color screen as some others have noted. I don’t think much is missed by not having a color screen, as there’s no information displayed that twould benefit from color. The display resistive touch screen is easy operation!
IC-7100 User Evalutatio & Full Test Report by VA7OJ, Adam (!a report of 48 pages)
This Report describes the evaluation of IC-7100 (S/N 02001352) from a user perspective. - Appendix 1) is a comparison of IC-7100 and IC-7000 features in tabular form. – Appendix 2) presents results of an RF lab test suite performed on the radio. Adam also writes: “I was able to spend a few days with the IC-7100 in my ham-shack, and thus had the opportunity to exercise the radio’s principal features and evaluate its on-air behavior”. – (thanks to Adam).
Il Report di ben 48 pagine in pdf, descrive ampie valutazioni come utente dell’IC-7100 (S/N 02001352 US version) – Nell’Appendice 1) vengono comparate, in forma di tabulato, le caratteristiche principali del IC-7100 e del precedente IC-7000 – Nell’Appendice 2) sono presentati ampi risultati delle misure e dei vari test nel laboratorio RF di Adam sul nuovo transceiver Icom. – Adam scrive anche: “Sono riuscito a trascorrere alcuni giorni con questo IC-7100 nella mia “baracca” di radioamatore, quindi ho avuto la possibilità di provare le caratteristiche principali della radio e valutarne il comportamento On-air” (Grazie ad Adam per l’interessante recensione).

Small extracted from the larger report 07/25/2013 (© 2013 A. Farson VA7OJ)
4.3. As one would expect of a high 1st IF (“up-conversion”) superhet architecture, image and 1st IF rejection are superb (> 110 dB). These figures are unachievable with an in-band (“down-conversion”) 1st IF design.
Test A2: Reciprocal mixing dynamic range (RMDR): In this test, a strong “undesired” signal is injected into the receiver’s RF input at a fixed offset Δf from the operating frequency. (etc. see the complete pdf!)
Test Conditions: SSB mode, 2.4 kHz filter (IF DSP), preamp off (IPO), ATT off, DNR off, NB off, DNF off, Notch off, Contour off. AGC Slow, negative offset. Roofing filter: 3 kHz (R3). RMDR in dB = input power – MDS (both in dBm). The RF input power Pi is increased until the receiver noise floor increases by 3 dB, as measured at the audio output (etc. see the complete pdf!)
Δf kHz 2 / Pi dBm -38 / RMDR dB 82 — Δf kHz 5 / Pi dBm -30 / RMDR dB 90
4.1 It will be seen from Tables 2 (RMDR) and 3 (DR3) that at 2 kHz spacing, the measured 82 dB RMDR value values is slightly higher than measured DR3. This indicates that although the measurement is phase-noise limited, there is still a measurable component due to front-end non-linearity.
!! At 5 kHz spacing, RMDR and DR3 are 90 dB and 81 dB respectively, indicating a fairly rapid fall-off in phase noise between 2 and 5 kHz offset. (…… etc. see the complete pdf!)
4.6. As mentioned in the test descriptions above, no trace of ALC overshoot or spikes was observed at any time. (…… etc. see the complete pdf!)
4.8. Overall, it is felt that the FTDX-1200 is a very good performer and an excellent buy in the mid price range
SCU-17 USB-2 Interface Unit – The FTDX-1200 can be connected to a PC with a USB cable through the use of an optional SCU-17 Interfeace Unit. This unit will support CAT, USB Audio In/Out, TX control (PTT, Key, Shift), and Firmware updates.

IC-9100: Interior views, features summarized, first impression, dual receiver but not same band, limits EMCOM. High price to base, and many optionals required for full operation. How to Expand the Receiver range.
Icom V.10GS0190 brochure and it looks like the dual receiver works in all modes simultaneously, but not on the same band • The IC-9100 has 3 independent receiver circuits from the antenna connector to the 2nd IF image rejection mixer • The IC-9100 will receive simultaneously (with mixed modes if desired) on any of the band pairs shown in the “Independent dual receivers” table on the IC-9100 brochure • It severely limits the usefulness for Emergency Communications (EMCOM) by not being able to monitor the same band with both receivers • For that matter, it limits if for DX and contesting, where you are listening in two places of the HF band at the same time. • The architecture of the IC-9100 (only one 1st mixer and LO per receive chain) precludes same-band Dual Watch operation.
The optional UT-121 Unit provides D-STAR DV mode digital voice and low speed data communication. [Note] It doesn’t have the Icom ID-1′s DD “high-speed” data feature! - Installing the optional UX-9100 box and his IF PCB the IC-9100 fully covers the HF/50, 144, 430/440 and 1.2GHz amateur bands in multiple modes. – RX expansion range (see last picture above): Frequancy coverange (not guaranteed!) 30kHz to 60MHz / 108 to 174 MHz / 420 to 480MHz 7 1240 to 1320MHz – Disassemble the radio, locate diode matrix behind the front panel and remove D1504 and D1505 for full Rx coverage, !! work with great care, risk of damage to the PCB – Assemble the radio and operate the full reset by olding [F-INP-ENT] + [M-CLR] and turn power [ON].

Here follows a short summary by © www.radiocronache.com taken from ©RadCom 01/2011 – (View the 01/2011 ©RadCom Magazine to read the full review by Peter Hart. A large and very interesting technical work, thanks) –
Link t0: RSGB Abaut RadCom and news web-page (-Members’ only)
The TS-590S is a single receiver tuning 30 kHz to 60MHz, although the performances is specified within the amateur bands. – The menu system is very comprehensive with 88 items, it uses scrolling display annotation. – Menu items allow for both fast and slow linear switching separely for HF and 50MHz but there is only one linear control line. - For use with transverters, the display can be set to indicate the trasverter frequency. Three digits are available for the MHz segment, eg 144 or 432.
Measurements – Peter evaluates separately two path: RX1 down-conversion and RX2 up-conversion. ————– (Short summary data)
The rejection of IFs and image for the RX1 down-conversion path was typically 75dB to 90dB (1*) – For the RX2 up-conversion path these figures were typically better than 90dB. – He searched carefully for other spurious responses as DDS circuits tend to be prone to this problem. – RX2 was very clean with no responses less than 80dB down. – RX1 was exceptionally clean with no other responses less than 100dB down (2*).
- (1*) FTdx-5000 the 9MHz IF rejection on 10MHz it was only 54dB, and on 7MHz it was 74dB. - (2*) FTdx-5000 the first mixer image was only down by 55dB to 70dB (>RadCom June, 2010 review)
IP3 Intercept and IMD3 Dinamic figures for bands (1.8 3.5 7 14 21 MHz) that use RX-1 the measurement was made 2.3kHz bandwidth. By measuring in 2.8kHz bandwidth all bands (1.3 3.5 7 10 14 18 21 24 28 50 MHz) use RX2 path.
—– RX1 path USB mode (50kHz Spacing)
7MHz Preamp OFF – Bandwidt 2.3kHz: IP3 +31dBm IMD3 105dB
7MHz Pream ON — Bandwidt 2.3kHz: IP3 +22dBm IMD3 105dB
—– RX2 path USB mode (50kHz Spacing)
24MHz Preamp OFF – Bandwidt 2.8kHz: IP3 +18dBm IMD3 98dB
24MHz Pream ON – Bandwidt 2.8kHz: IP3 +6.5dBm IMD3 96dB
Close-in IP3 and IMD3 figures were made in 500Hz bandwidth with RX1 on 7MHz and RX2 on 10MHz.
- RX1 uses the 500Hz bandwidth roofing filter. – RX2 the 2.7kHz bandwidth filter at the second IF and 15kHz rofing filter at the first IF. - The results for RX1 path are really excellente, achiving 103dB IMD3 at 2kHz spacing and 90dB at 1kHz! – The results for RX2 path show the efect of the wider roofing filters (15kHz+2.7kHz). Then at 2kHz and below the signal enter the second IF filter passaband and the AGC takes effect.
—- RX1 7MHz Preamp OFF CW mode – DSP Bandwidt 500Hz – IF Roofing 500Hz:
2kHz sapcing IP3 +23dBm IMD3 103dB / 10kHz spacing IP3 +30.5dBm IMD3 108dB
—- RX2 10MHz Preamp OFF CW mode – DSP Bandwidt 500Hz – IF Roofing 15kHz and 2nd IF 2.7kHz:
2kHz spacing IP3 IMD3 see text below / 10kHz spacing IP3 +21dBm IMD3 103dB
A somewhat complex AGC system is used, detecting signal level in three places within the DSP signal path. – The close-in strong signal performance in some cases may be limited by the AGC when a strong signal falling inside the filter roofing but still outside of the final channel filter will result in AGC action. – This can be heard as a quietening of the receiver from a very strong signal just outside of the channel passaband. - The effect is most noticeable with the wider roofing filters and is not an issue with the 500Hz roofing filter in circuit. – [Note] clik the thumbnails to enlarge!

The 9MHz IF rejection on most bands was greater than 100dB, but on 10MHz it was only 54dB, and on 7MHz it was 74dB. VRF front-end tuning improved these figures by 20dB. The first mixer image was only down by 55dB to 70dB but VRF improved this to better than 75dB.
Spurs on the synthesiser resulted in a number of unwanted receiver responses, notably at approx +/- 425kHz from the received frequency at only 65dB down on the VFO-A rx and at +/- 40kHz down by 85dB. VRF improves these figures but only marginaly on the higher bands.
Third order intercept (IP3), dynamic range (IMD3) and blocking figures were outstanding with the appropriate Roofing filters selected (See the Table-1*). The VFO-B receiver dynamic range is nont quite as good as the VFO-A receiver but is still very respectable.
Link to: The RSGB webpage – RadCom Magazine
La rejezione IF a 9MHz per la maggior parte delle bande risulta superiore a 100dB, ma sulla banda dei 10MHz scende a soli 54dB, e sulla banda dei 7MHz risulta 74dB.- L’uso del VRF tuning del front-end migliora queste figure di circa 20dB. L’immagine del primo mixer risulta attenuata solo da 55 dB a 70 dB, ma con il VRF si ha un miglioramento al valore di 75dB. Le spurie del sintetizzatore produce una serie di risposte indesiderate al di sotto di soli 65dB rispetto all frequenza ricevuta, in particolare a circa +/- 425kHz dal centro della frequenza sul VFO-A (main rx), ed ancora a +/- 40kHz sono al di sotto di 85dB. L’inserimento del circuito VRF migliora queste cifre, però solo marginalmente sulle bande più alte di frequenza.
L’intercept point di terzo ordine (IP3), la gamma dinamica IMD3 e la dinamica di blocco hanno valori che variano in base alla banda passante del Roofing filter selezionato (Vedere Tabella-1*). Il ricevitore del VFO-B (sub rx) ha a sua volta una dinamica non altrettanto buona come il ricevitore VFO-A (main rx), ma comunque è molto rispettabile. – !! Emerge dall’articolo di Peter Hart una questione che lo preoccupa: la effettiva capacità di rejezione di segnali spuri del ricevitore A.
