Do ut des Story!! … November 07, 2007 (source: Btown Monitoring Post blog)
….omissis…..
Motorola, Inc. (NYSE: MOT) will launch a tender offer to acquire a controlling interest in Vertex Standard Co., Ltd. (JASDAQ: 6821). Upon successful completion of the tender offer and subsequent restructuring process, Motorola will own 80% of Vertex Standard and Toko Giken, a privately held Japanese company, controlled by Jun Hasegawa, current president and CEO of Vertex Standard, will retain 20%, forming a joint venture. On 5 November 2007, the Board of Directors of Vertex Standard expressed their support of the tender offer. Yaesu, of course, as one of the Vertex Standard operations, will be included in this exciting development…… omissis….

!! This latest announcement says that they’re transferring the  LMR business to Motorola and that the new Yaesu will be “wholly owned by the founder’s family”, I guess this means that Motorola is selling their stake in Vertex Standard back to the Hasegawa family… Do ut des !!

R&S® M3TR Software Defined Radios Multiband, Multimode – New software V.7.0

R&S®M3TR Software Defined Radios (Front panel on the image) – The new software Ver.7.0 supports third-generation Automatic Link Establishment (ALE 3G)* in line with the STANAG 4538 NATO standard. If a shortwave consumer receiver could do what this shortwave milspec transceiver hi!!

The heart of the new integrated communications system is the lightweight R&S®MR300xH/U manpack transceiver (1.5 MHz to 108 MHz or 25 MHz to 512 MHz), which offers solutions for all aspects of tactical communications - New Software Makes Rohde & Schwarz Shortwave Radios As Easy To Use As IP Phones -
Last-ditch voice enables reliable voice transmission even when the noise is stronger than the voice signal, ie with a negative signal-to-noise ratio. - The quality of shortwave links heavily depends on ambient transmission conditions such as solar radiation and atmospheric ionization – The software automatically adjusts the transmission rate to accommodate prevailing conditions. – Release 7.0 of the software also features the high throughput data link (HDL) protocol that allows transmission rates of up to 10 kbit/s under optimal conditions.

ALE 3G * - The latest ALE standard uses accurate time synchronization via GPS-locked clocks or a time server to achieve faster and more dependable linking. – It is generally known as 3rd generation or 3G ALE.

FTdx-5000 Review from RadCom June 10 by G3SJX – Here only some data and a summary

FTdx-5000 measured performance → Source: RSGB RadCom  June, 2010 by G3SJX – Table 1*
[*Note]: here, only some of the many performances misured – View the RadCom Magazine to read the full review by Peter Hart) – !! IP3, IMD3, and Blocking figures were outstanding with the appropriate Roofing filters selected. !! The only area for concern is the receiver spurious signal rejection….

Sensitivity SSB 10dBs-n:n 7MHz band: IPO-1 →0.7uV (-110dBm) PREAMP-1 →0.18uV (-122dBm) PREAMP-2 →0.09uV (-127dBm)
Intermodulation (Spacing 15kHz) 2400Hz bandwidth 6kH Roofing USB 7MHz band: IPO-1 →IP3 +37.5dBm IMD 105dB PREAMP-1 →IP3 +26dBm IMD 105dB PREAMP-2 →IP3 +18dBm IMD 103dB
Close-in Intermodulation on 7MHz Band 500Hz bandwidth CW IPO-1:
Spacing →2kHz (15kHz Roofing) IP3 -8.5dBm IMD 77dB – (6kHz Roofing) IP3 -4dBm IMD 80dB – (3kHz Roofing) IP3 +33dBm IMD 106dB – (600Hz Roofing) IP3 +37dBm IMD 109dB
Spacing →10kHz (15kHz Roofing) IP3 +38dBm IMD 108dB – (6kHz Roofing) IP3 +39dBm IMD 109dB – (3kHz Roofing) IP3 +38dBm IMD 109dB – (600Hz Roofing) IP3 +38dBm IMD 109dB

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.

The latest Firmware Updates Ver.2.21 IC-7800, 1.12 IC-7700 and 1.02 IC-7600, of 2010/04/01

The DSP IF filter shape factor (-6/-60 dB). This is the ratio of the -60 dB bandwidth to the -6 dB bandwidth, which is a figure of merit for the filter’s adjacent-channel’s rejection. The lower the shape factor, the “tighter” the filter. – The two type of DSP filter shape factor for each SSB, SSB-Data and CW can be selected independently from soft and sharp.
A sharp profile with a flat passband and soft profile with a more rounded passband (Twin Passband Tuning [TWIN-PBT] is also easily provided, which enables the filter sides to be both indipendently moved and narrowed, the DSP also provides audio filtering and shaping functions). Depending on  the operating situation, for example handling a pile-up or receiving a very weak signal, you can flexibly change sharp and soft filter shapes or reduce or shift the filter width, even while receiving a signal, by a simple push of a front panel key. See the latest Ver. for each model and Link below..
