Configuration, RRC 1258 / Where is bootloader download?
« on: 2014-07-01, 05:01:34 »
Where can one find the latest bootloader download?

I am using Remote Rig firmware 2.78 and TS-480SAT. Internet connection is provided by AT&T/iPhone 5S hotspot and a Netgear WNCE2001 Wifi Adapter. Rx jitter 6, jitter delay 7, audio quality 1, Dynamic DNS through Remote Rig.

The problem is the receive audio has a hiccup about every 10 seconds making listening uncomfortable. Any suggestions to fix these dropouts?

FYI, K7FD will be operating remotely during the contest this weekend - hope to work you! 100 watt TS-480SAT and 3 element Mosley TA-33 up 19 meters...

I know I'm preaching to the choir here, but the Remote Rig is a real game changer. I couldn't be more pleased with the increased flexibility it has given my portable operating. The ability to fire up my TS-480SAT away from home and yet have all the controls in front of me wherever I'm at is phenomenal; my hats off to Microbit!

I would like to turn my beam remotely but do not wish to use a laptop or software to do so. I would like to do it with a real controller. Is anyone using rotator hardware (control head) on the control RRC end to turn their beam?

If so, how are you doing it and with what hardware? Would it be possible to use two MDS RC1-G Yaesu G450 controllers?

I have had several email requests to supply a photo of the portable RRC set up; if interested, I now have a photo on my QRZ page:

Since adding a 3G antenna to the air card, my AT&T connections are considerably better...

My fist checks out OK, so can someone tell me what the secret is? Try as I might, when I send a letter Q it immediately skips the dit and makes an O.

Iambic A or B makes no difference. Is there some setting I am missing? Thanks for any insight!

73 John K7FD... and lucky I have no Q in my call  :)


FYI, after using the AT&T 3G USBConnect air card with the RRC boxes for the last week or so, we have discovered the average data usage is clocking in at about 60MB per hour. Since we have a monthly 5GB data plan, this works out to be about 83 hours per month of operating available before we run out (5000MB data plan / 60MB used per hour = 83.333 hours of operating available.

Carrying this a bit further, 83.333 / 30 days in a month = 2.77 hours of operating time per day. As a point of interest, our plan costs $50 per month US$. Getting granular, you could say it costs us about 60 cents an hour when we operate using the 3G USBConnect card  ;D

In any event, where my xyl N7SG and I operate weekends only from our recreational vehicle, this gives us plenty of 'talk time' per day...

We are totally satisfied using the AT&T 3G to connect our control RRC to the internet. The connection has proved very solid, jitter free, and just like operating from home. Using the Kenwood TS-480SAT...with a average of ping rate of 192ms & settings of packet size 20, jitter buffer 3, jitter delay 4, audio quality 1, keyer lf 350 delay 200...our results have been excellent.

I have everything working well on SSB but cannot seem to get CW working smoothly. With a 3G connection, voice/ssb seems to transmit smoothly with very few breaks. CW however is another story. I cannot send a simple CQ without total garbling of characters sent. This sound as though they are stepping on each other...this at about 15 wpm. Why is ssb 'ok' and yet cw is barely copiable?

Are they settings with jitter, etc. that would be 'best' for cw? If so, what would they be? I can't seem to come up with the magic combination, hi.

Appreciate any input...maybe the 3G connection just can't handle my fist? :)

Today I hooked up the remote rig units via AT&T wireless and a USBConnect Lightning Sierra 305 aircard. In addition, I am using a ZOOM 3G wireless travel router, thus negating the need for a laptop. Just stick the aircard in the ZOOM and run Ethernet cable from back of the ZOOM to the control RRC. The ZOOM travel router, by the way, runs from an internal battery, making it somewhat portable.

With this set up, I am happy to report crystal clear and jitter-free communications using my TS480SAT from anywhere I can connect to a 3G signal. There were zero dropouts and the connection was rock solid. This is very different than I experienced connecting to most wi-fi hotspots.

My data plan is 5GB per month, so will keep a watchful eye on usage! However, so far it seems an hour of operating hardly put a dent in the 5GB plan. Will keep you posted on this...

Has anyone else noticed the 'white noise' hiss in the TS-480SAT internal speaker when the volume control on the Kenwood is set to zero? I also notice the same hiss when using the SP jack in the control RRC with my headphones. The hiss seems like it goes down and away as you increase the volume control. It's a little too loud for me when using headphones but not so bothersome when using the speaker...

The RRC Setup Manager cable is unplugged; whether it is in or out makes no difference in the hiss noise...

Anyone have the magical settings to connect from open wi-fi back to their radio RRC's? I am using a laptop and LinkSys WET610N wireless bridge to scan for open wi-fi spots, connecting, then moving Ethernet cable to my control RRC and TS-480SAT.

The only success I have had with this lash up, so far, has been connecting to a 'visitor wi-fi' at my workplace. There I scanned with the wireless bridge, found the wi-fi, entered the password, connected, moved Ethernet cable from laptop to control RRC, and the TS-480SAT immediately connected to the radio RRC when I powered up the Kenwood faceplate.

So I am wondering what the difference is between the wireless wi-fi at my workplace and wireless wi-fi hotspots. I have tried the local library, Starbucks, McDonalds, etc....all without successfully connecting to the radio RRC.

One other note, when connected to the workplace wi-fi I can browse to my DynDNS address and bring up the webpage to see radio RRC settings, no problem. However, when I connect a laptop to Starbucks, McDonalds, etc. I can NOT browse to my DynDNS address. Does this mean these wi-fi hotspots are blocking something?

As Mitch says, there needs to be a 'Networking for Dummies' for guys like me, hi! All replies appreciated...

FYI, I found if the SPI (stateful packet inspection) firewall was enabled (default setting) in my Netgear RangeMax 240 router, I could not connect RRC's remotely.

To remedy, I had to uncheck the SPI firewall setting in the router.

Hope this is helpful to someone else wrestling with their remote connections!

Hi All...

My question is: how does the control unit know how to contact the radio unit sitting out my router in my shack? What setting(s) specifies this?

I have been successful connecting the 2 units, communicating over my home router, and controlling the TS-480SAT. I have not, however, been successful (yet!) connecting to the radio RRC from the control RRC away from the shack.

After testing the set up locally in the shack, I reset the control RRC to DHCP and entered my DynDNS address in SIP contact field. My router at home is an Netgear Range Max 240 wireless router. All port forwarding numbers have been double checked; in addition, I added to my DMZ...

If anyone has been down the road and has any ideas, it would be greatly appreciated!!
