Flex-Radio Flex-5000A Impressions after Six Months or so « With Varying Frequency – Amateur Radio Ponderings

Flex-Radio Flex-5000A Impressions after Six Months or so « With Varying Frequency – Amateur Radio Ponderings: "My impressions of the Flex-5000A SDR radio keep going up.

I’ll have to admit to having done less than a 1000 QSOs using the Flex-5000A. Based on my still modest sample the impression of quality and utility are 100%+

The listening ability is exceptional. Using the Filter-Matrix, RX-Equalizer and the Noise-Reduction/Reception-Processing Matrix the number of stations I can hear and isolate is extraordinary. Operating at times where other stations complain about the lack of stations heard, I often have a large number of stations that can be heard on the Flex-5000A.

The number one feature I am enjoying is the Display. The various Panadapter displays have something for every operator. Setting the viewed with to take in the most bandwidth makes getting a band snapshot easy. Increasing the focus to allow more precision in selecting an observed signal to listen to certainly helps for DX Hunting.

Transmit Audio reports have been excellent. A Yaseu MD-200 Desk Microphone is the current setup, though I plan to experiment with a boom mounted mic & foot-switch to see if I can gain some desk space back, and to use a more directional pickup patten.

The Dell computer is doing great. Typically I will have PowerSDR, MixW and Safari (3) running. I’ve avoided updating to the Safari 4 Public Beta having observed its huge appetite for system memory and how it never gives up memory it no longer needs.

The software combination seems content with each other, tracks well and is stable.

I’ve written before about two observed software anomalies, an occasional reduction in audio out after periods of idle and frequency excursions (which may be my fault). I haven’t been able to duplicate either, so they may be operator error.

Short term there are a number of tasks to accomplish in my installation:

* Two longer shielded DVI cables are here and ready to install. The Dell supplied cables are too short for my physical configuration.
* The boom mike experiment to gain desk space.
* The Contour ShuttlePro Multifunction Controller needs to be installed & configured.
* Room has to be found to put the 6m Amp on-line.

Additionally the K9ZW shack setup wit the Flex-5000A needs a general tidy-up with cable-ties put on cables, power supplies moved so the switches are not hidden, the PowerMaster SWR Meter & Green Heron Rotor control hooked up to the computer and possibly replacing the RatPak antenna switch with one that can be computer controlled.

Lots of excuses to get lost in the shack for a few hours here & there!

Wild Fire Destruction in Port Lincoln Australia

http://www.youtube.com/watch?v=5_yHlgI9Jqs


This video shows what is left of our clubroom following the devastating
bushfire that threatened Port Lincoln on 23rd Dec 2009.
All our equipment has been lost, priceless historical radios have been
destroyed, all our paper based records and photos are gone.
Thankfully no lives were lost but 12 homes were destroyed in this fire. It's not
going to be a merry Christmas for some families this year.

Sad News - Wild Fire Destruction in Port Lincoln Australia

While the loss of our clubrooms and equipment is sad, it does pale into insignificance when you compare it to the loss of 12 family homes two days before Christmas.

But there is one story from the fire that promotes D-Star and I though I would share it here.

By the time I first noticed the fire while I was at work,
http://www.youtube. com/watch? v=ln456kbAvV4
the cellphone service was fully congested, I was unable to make calls or send SMS messages.
I did however have my IC-91AD handheld radio with me. I was planning on connecting up to REF012 B to check in on the San Diego D-Star net at 1430 (my time).
Instead I connected VK5REX B to REF003 C and put out an emergency call for assistance from anyone who had immediate access to a telephone.
Steve VK5ZSW replied and I passed my home phone number info to him so he could contact my wife to let her know that I was OK and that I was going to move to safer ground. The message was dutifully passed along and Steve confirmed that my wife got the message. Although Steve was some 170+ Km away in Moonta on the Yorke Peninsula, he was able to use the VK5REX repeater perfectly.
Ross VK3HBS also heard my call through REF003 C and he too rang my wife with the message.
It wasn't long after this that the power to Port Lincoln failed. Although the VK5REX B repeater has a massive backup UPS and 85 kVa generator, the other end of the WiFi internet link that the gateway uses did not, so I lost internet connectivity. This is now being worked on so future power failures will not stop gateway operation.

Steve remained at his radio during the drama and it was reassuring to know that he was ready and willing to help with communications as needed.

I also used the VK5REX B D-Star repeater to talk to my father Tony VK5RF, while I went home to gather essential items ready for evacuation. By the time I got home the wind had changed and was blowing smoke and ash over a major portion of Port Lincoln.
http://www.youtube. com/watch? v=Uuz8ylTKUzk
http://www.youtube. com/watch? v=VagyeMXfSTw
I had no idea how bad things would get so I had to assume the worst was yet to come.
While my wife does not hold an amateur license, she was able to use the UHF CB radio in our Toyota truck to talk to me in my work car. She was heading (with our 11mo son Ethan) to my parents home in the marina area of Port Lincoln, way out of the path of the fire.

The cell phone service was still very congested and once again it was reassuring to have D-Star as a reliable communications medium during this emergency. I was able to let everyone at my parents home my progress as I made my way through smoke filled streets, the work car loaded with essential items taken from our home (photo albums, office computer, papers, charged gel batteries, Christmas presents, my wife's insulin, etc.)
Apart from the loss of the gateway, the RF side of the D-Star repeater worked perfectly and provided me a reliable way to communicate when the cell phone system failed.

TX frequency coverage expansion for ICOM ICE92D

TX frequency coverage expansion for ICOM ICE92D Remove D4 as shown below:

Procedure:

# Turn off the unit, remove the battery or battery case and then remove the six screws on the back side of the transceiver
# Carefully separate the front and back halves of the housing (there are a cable harness and a flat cable connecting the two halves together inside. The visible circuit board in the keyboard/display half is the logic unit)
# Unlock the locking flap at the flat cable connector on the logic unit and gently pull out the flat cable (after this step the two halves can be turned down side by side and the logic unit is conveniently accessible)
# Locate diode D4 on the logic unit just below liner codec IC 503 and remove it by means of SMD unsoldering equipment or a suitable soldering iron (if no special SMD unsoldering equipment is available a soldering iron with a sharp screwdriver tip can be used. Do not use more than 25 W for the soldering iron and edge the tip sharp enough. Heat up the two solder points on one side of the diode simultaneously by touching them with the flat soldering iron tip (don't touch for more than 2 or 3 seconds) while pulling up the diode with a sharp pair of tweezers. The surface of the diode will melt and doesn't look very beautiful after the "surgery" but it will no longer be of any use...
# After removal of the diode check the logic unit carefully with a magnifying glass and remove any residuals with an appropriate sized and not to hard paint brush
# Reconnect the flat cable to the logic unit and rejoin the two housing halves paying attention to the correct fit of the Oring seal that is responsible for the waterproofness of the transceiver
# Reinsert and tighten the six screws removed in step 1 gently.
# Switch on the transceiver and check the TX frequency coverage. If necessary do a full reset.


just be carefull when removing the diode.

-----------------------------------------------------------------------------------------
Or you could do it this way all is at your own risk

Removing the tag / sticker to do the mod might give you two problms.
1. The hole in the chassis is very narrow and it is hard to get to the diode.
2. When the tag is removed it is hard to get it back in place as it where cause the plastics will get deformed while removal.

I work for an Icom dealer and have done tenfold of these modifications. What I find the quickest way is to unscrew the 6 screws in the back cover. Move the front slightly to the left to get to the diode.
This operation is usualy done in less than 10 minutes.

MB6AM, 2m D-Star Simplex Node:

21/11/2009

MB6AM, 2m D-Star Simplex Node: Tring, Herts.


After several weeks in testing, MB6AM went live this afternoon, sharing

the same mast as the 70cm GB3TU repeater. MB6AM is located in Tring, North

West of London and is well appointed to provide Digital Voice (DV) coverage

across many of the Home Counties and parts of Oxfordshire.


MB6AM is the reincarnation of the old GB7AM packet node, using the same

antenna and 2m frequency. Chris, G0WTZ, kindly donated his own Yaseu

FT-7800R for the project and David, G4ULF provided custom software to link

into the global D-Star network. G4ULF's software was developed with the full

cooperation of the Trust Server team and has been fully tested for G2

compatibility, with support for G2 direct routing and dplus linking across

to other D-Star repeaters, via the Internet.


MB6AM will be routinely connected to reflector REF013B which has been

dubbed TechNet, a meeting place for repeater keepers, software developers

and D-Star hardware hackers. User control of dplus linking and unlinking is

enabled, so mobile users on the busy M1 and M40 motorways, can re-task the

simplex node as required. When the dplus connection is left unlinked, a

script will automatically re-establish contact with TechNet.


To access MB6AM, users should configure their radios in simplex mode on

144.8625 MHz, with no RPT settings required. If RPT settings are used, then

the following settings must be programmed:


YOUR: CQCQCQ
RPT1: MB6AM^^C (^ = space)
RPT2: MB6AM^^G

Duplex Offset: +/- 0 MHz


D-Star users can make use of all the usual dplus and G2 routing commands,

so they can link to other nodes or call directly around the D-Star network.


Iain, G0RDI, the NoV holder for MB6AM, extends his personal gratitude to Rod Wilkinson (Ofcom), Chris (G0WTZ), David (G4ULF) and Darren (G7LWT) for their assistance with the implementation of this project. MB6AM is the first simplex G2 gateway in the UK.

  Track Live D-Star APRS         
  

If any Users of GB7SF Would like their radio programming, or get to know more about the ICF  files Click M1ERS

To program your radio for local use on the GB7SF Repeater's) follow the instructions below:

Programming For Local Use 


To program your radio for local use on the GB7SF repeater(s) follow the instructions below: NOTE To allow your audio to be heard by all users, the UK-IT now advises using port G in RPT2 for all connections.





To Locally Access the 2 m Repeater (active now)
Frequency 145.7375 Negative Offset -600 Khz
MYCALL = Your Call Sign
URCALL = CQCQCQ
RPT1 = GB7SF  C (C in 8th position)
RPT2 = GB7SF  G (G in 8th position)   << *NOTE* >>





To Locally Access the future 430 Repeater
Frequency 439.7375 Negative Offset -9Mhz
MYCALL = Your Call Sign
URCALL = CQCQCQ
RPT1 = GB7SF  B (B in 8th position)
RPT2 = GB7SF  G  (to be heard by all users !)



Programming For Gateway Use

To access other repeaters and users via the Gateway your call sign must be registered on the Gateway System.
You must only register oncePlease contact M1ERS to apply  for registration. If you registered through another Repeater's Gateway System, you need not register here.  

When making a Gateway call make sure you state that you are on the Gateway.  After each call listen for a sufficient period of time to allow responding stations to set their radios to answer through the Gateway.

To program your radio to contact a specific station via the GB7SF Gateway follow the instructions below:


To  Contact A Specific Station Via The 2 m Repeater Gateway
Frequency 145.7375 Negative Offset -600 Khz
MYCALL = Your Call Sign
URCALL = Call Sign of station being called
RPT1 = GB7SF C (C in 8th position)
RPT2 = GB7SF G (G in 8th position)





To  Contact A Specific Station Via The future 430 Repeater Gateway
Frequency 439.7375 Negative Offset -9Mhz
MYCALL = Your Call Sign
URCALL = Call Sign of station being called
RPT1 = GB7SF B (B in 8th position)
RPT2 = GB7SF G (G in 8th position)



To program your radio to make a general call to a remote repeater via the GB7SF Gateway follow the instructions below:


To Make A General Call To A Remote Repeater (Example GB7IC) Via The 2 m Repeater Gateway
Frequency 145.7375 Negative Offset
MYCALL = Your Call Sign
URCALL = /GB7IC B  (Module In 8th Position) The Module is A, B or C depending upon the remote repeater module to be accessed.
RPT1 = GB7SF C (C in 8th position)
RPT2 = GB7SF G (G in 8th position)





To Make A General Call To A Remote Repeater (Example GB7YD) Via The  430 Repeater Gateway
Frequency 439.7375 Negative Offset -9Mhz
MYCALL = Your Call Sign
URCALL = /GB7YD B (Module In 8th Position) The Module is A, B or C depending upon the remote repeater module to be accessed.
RPT1 = GB7SF B (B in 8th position)
RPT2 = GB7SF G (G in 8th position)



When making a general call to a remote repeater URCALL must start with a / followed by the callsign and then the letter of the RF module on the remote system you wish to transmit from.  The module letter must be in the 8th position regardless of call sign length.  Common RF module identifiers are:

A = 1.2 gig

 B = 70 cms

    C = 2 meters

    G = Gateway

To  utilise the one touch capture feature, on the IC-E91 press the CALL button for 1 second whilst the gateway station is still transmitting.  For the IC- 2820 press F twice and then R>CS button.
Very Important:

When you sign after a gateway call you must return URCALL to CQCQCQ.  Should you fail to do so your subsequent calls will still go via the gateway to the user and/or repeater indicated in URCALL.

What D-Star is about

D-STAR transfers both voice and data via digital encoding over the 2 m (VHF), 70 cm (UHF), and 23 cm (1.2 GHz) amateur radio bands. Voice is encoded as a 3600 bit/s data stream using proprietary AMBE encoding, with 1200 bit/s FEC, leaving 1200 bit/s for data encoding. On air bit rates are 4800 bit/s over the 2 m, 70 cm and 23 cm bands. Digital only data can be sent at 128 kbit/s only on the 23 cm band. Radios providing data service use a RS-232 or USB connection for low speed data (1200 bit/s) and Ethernet for high speed (128 kbit/s) connections to allow easy interfacing with computer equipment.
