Function differences & Impression : BCD436HP vs UBCD3600XLT

As I have said before, we check differences between Uniden BCD436HP and the UBCD3600XLT. Additionally, I will show the first operating impression for the UBCD3600XLT. The firmware version of my BCD436HP is 1.11.17 and of my UBCD3600XLT is 1.00.01.

The label on the UBCD3600XLT says “POWER REQUIREMENT : 5V DC 1000mA”. The BCD436HP tells 5V DC 500mA. As far as I see the instructions of the BCD436HP and the UBCD3600XLT, receiver sensitivities of the UBCD3600XLT is lower than that of the BCD436HP and Close call sensitivity of the UBCD3600XLT is totally higher than that of BCD436HP. Perhaps, there are some modifications in the UBCD3600XLT. If it is true, battery would last only half of the BCD436HP.

As the instruction manual mentioned, receiver coverage of the UBCD3600XLT is 25-512MHz, 806-960MHz and 1240-1300MHz, which is narrower than BCD436HP (758-805.995MHz not covered with). I have succeeded to import a HPE file that I am using on the BCD436HP into UBCD3600XLT Sentinel software. Although DMR Tier III and EDACS PROVOICE seem to be equipped with the UBCD3600XLT by default without any expense, SYSTEMs that include out of the reception frequencies that has been preset are fully ignored by the UBCD3600XLT even if there are some frequency that can be heard in the SYSTEM . For instance, if a SYSTEM includes more than one 770MHz frequencies that cannot be heard on the UBCD3600XLT and more than one 144MHz that can be heard both BCD436HP and UBCD3600XLT, the SYSTEM is not recognized by the UBCD3600XLT itself (the SYSTEM name not displayed at all). But frequencies not received by the UBCD3600XLT can be input on the UBCD3600XLT Sentinel software (Version 1.00 revision 00).

What I want the UBCD3600XLT to equip with is dPMR/NXDN/D-CR capabilities. I doubt why the UBCD3600XLT for the Euro market does not have dPMR digital mode.

The UBCD3600XLT is mostly identical to the upgraded BCD436HP. If you are in the US and have improved BCD436HPs, the UBCD3600XLT may not be attractive. If Uniden makes more effort to develop digital scanners to add much more digital mode with codecs, the ICOM IC-R30 might be disappeared.

Will check sensitivity of the UBCD3600XLT and other differences from the BCD436HP.

First Look : Uniden UBCD3600XLT with BCD436HP

Uniden UBCD3600XLT
I have got my UBCD3600XLT Digital and Analog scanner. Let’s check appearances of the Uniden UBCD3600XLT first of all.

Appearances of the UBCD3600XLT for European market is almost same as BCD436HP for the US market. There are some minor differences as below;
  • Bigger or smaller font on the keypads (bit a little)
  • Characters "ZIP" -> "LIST", "WX"-> (removed) changed on the keypads
  • Back label : simpler texts than BCD436HP

Uniden UBCD3600XLT on sale around the EU countries

A Uniden scanner UBCD-3600XLT is now available in the EU region.

+ Uniden UBCD3600XLT in 2017 - Transmission1

Uniden UBCD3600XLT Digital Scanner

UNIDEN UBCD3600XLT which is similar to BCD436HP seems successor of UBCD3500XLT, EU version of BCD396XT. The appearance quite resembles BCD436HP.

The UBCD3600XLT includes DMR and EDACS Provoice by default without any upgrades. The frequency coverage is 25-512/806-960/1240-1300MHz, not same as the BCD436HP. Supplied accessories are not same. The UBCD3600XLT supplies USB Connection Cable and an AC Adapter.

As dedicated ZIP-Code Database from to setup UBCD3600XLT at ease is not currently available, users need to input and customize databases manually. I managed to obtain the UBCD3600XLT Sentinel software and tried to find "Update Master HPDB" option but not found like below;
Console of UBCD3600XLT Sentinel

I also tried to update firmware for my BCD436HP with UBCD3600XLT Sentinel software. My BCD436HP was recognized by the Sentinel but a Time-out Error was occurred. Firmware of the UBCD3600XLT may differ from BCD436HPs;
Time-out Error at updating firmware to BCD436HP

Next, I tried to import HPE files for BCDx36HP Sentinel software into UBCD3600XLT Sentinel. The result was OK;

If the imported HPE files that BCDx36HP Sentinel had already created indicate outband of the receiver coverage of the UBCD3600XLT, the UBCD3600XLT Sentinel may display some errors.

Price of the new UBCD3600XLT is 499EURO, about $530-540 excluding TAX and so on. There is no official information about UBCD3600XLT because Uniden seems to have no EU sales/support chains directly and also seems no official website for the EU customers.

Some scanner enthusiasts have already got the UBCD3600XLT. Would look into differences between UBCD3600XLT and BCD436HP some day.

Summary of ICOM IC-R8600 before purchase

IC-R8600 communications receiver is now available in my place.
IC-R8600 in ICOM Ham Festival on Dec., 2016
The instruction manual can also be read but written in Japanese. The Japanese price is 228000 Yen, about $2000 excluding tax. Quantity of the first lot is about 250 sets. Now I have picked up some brilliant features and compare with some features of AOR AR-DV1.
AOR AR-DV1 receiver (with SONY ICZ-R250TV behind)

In short, the IC-R8600 is a wide band receiver with digital mode decoder. Comparing to AOR AR-DV1, there are some functions such as IP+(IP3 distortion reduction) to improve unwanted interferences, variable NOTCH filter, Digital twin PBT(Pass Band Tuning with double sharp filters provided with DSP), variable Digital IF filters for SSB/CW/AM, variable Noise Blanker and CW-Reverse(which exchanges receiver sideband LSB/USB) that AR-DV1 with 1702D firmware does not have. Those are built on the IC-R8600. These features are especially for VLF, LF, MF and HF.

Anything else on IC-R8600? Yes of course! dPMR and NXDN descrambler(may not equipped with US version), digital reception history log (up to 50 logs), history csv saving, screen capture, voice recording, data saving onto a SD card like IC-7300 and ID-51 series, network clock synchronization, tone control, FM de-emphasis, speech, FSK decoder, IF output, remote Ethernet control via internet, analog S-meter output jack to connect your 9VDC of maximum voltage meter and so on.

But, no DMR, TETRA, Alinco and YAESU SYSTEM FUSION(C4FM) decoder currently on the IC-R8600. In my country, DMR, TETRA, dPMR, APCO P25 are not commonly used, while domestic digital SCPC format with A-CELP and M-CELP vocoders is mainly used by our government, which cannot be decoded because he restricts to hear his communication easily. There is no thought of "Public Safety" in my country like the US.

Still, the IC-R8600 attracts us because it has 4.3” large color LCD with touch screen and real time smooth & fast spectrum scope, high spec features for VLF – HF and digital voice decoders…. Compared to AR-DV1, the IC-R8600 seems cost effective. Will expect to upgrade much functions with newer firmwares.

I have ordered one and expect to get soon.

Maldoll Releases LASER GP Antenna SVT-2

New concept GP antenna is released from Hoxchin.

Hoxchin non physical antenna element SVT-2, prototype

The Hoxchin, which is well-known to release Maldoll antennas, SVT-2 is a ultra-wide band non-radials GP antenna that covers from MF to 1GHz without any physical antenna elements.

Element of the SVT-2 uses Wavemotion Dielectric LASER (green beam on the photo as above), which is developed by Hoxchin and a LASER Lab. in Pachistantan of an Eastern country. Beam of the Wavemotion Dielectric LASER works as an antenna for radios unlike conventional antennas with metal materials.

The Wavemotion Dielectric LASER alters part of density and length of the LASER beam and synchronizes with radio wave from/to your transceivers very fast. When transmitting, the Wavemotion Dielectric LASER resonates a frequency as an oscillator that is oscillated from positive feedback loop and then radiates from the internal LASER Diode directly. When receiving, radio wave from the air synchronizes with current length of the LASER. The Wavemotion Dielectric LASER fully covers from 1.5MHz to 1GHz not only transmitting but receiving.

Maximum length of the LASER is up to 330 Ft, which means half length of the radio wave on 1.5MHz lowest frequency.

Body of the SVT-2 is equipped with latest FPGA and DSP which enable it to make available at air pollutions conditions, strong windy and so on. Even on the strong windy day, there is the least impact affected to the SVT-2 because of no physical element. SWR always ensures less than 1.1.

Moreover, the SVT-2 can change 1000 times of the TRX frequency per second. When your receiver runs on scanning mode, length of the LASER (antenna) of the SVT-2 quickly follows up the receiver frequencies 1000 channels of max per second, which provides us the best transmission or reception performance every time.
As the SVT-2 has no mechanical switches such as relays and so on, it gives us silent amateur operations even overnight contest.

If you have two SVT-2, fading effect can be reduced sufficiently. We can choose two colors of the LASER that works as an antenna element. The following picture is an example of outdoor operations by hands with two SVT-2 but it cannot demonstrate the best performance for the SVT-2s.
Example of operating HF bands with two SVT-2s by hands (not recommended)

Please do not play STAR WARS, Ninja and so on with the SVT-2s. Hoxchin does not expect the usages.

The Hoxchin (Maldoll) SVT-2 will be available by this year. The price is $14400 MSRP. Although the SVT-2 is not cheaper than any radios, would try the two SVT-2s to reduce fading effects on HF. The SVT-2 will be most compact, lightest weight antenna in the HF category, thus, we will be able to operate HF bands much easier than usual.
