General discussion forum / Re: TS590 & 590SG twin
« on: 2019-01-24, 19:28:17 »
Although the original posts are old, I would like to raise the query again. I suspect the answer is 'no' but can a TS-590SG be used in Twin mode with a TS-590S? Maybe be they can be used but not all features are supported? Any advice appreciated. Thanks.

I had (and still have to some extent) a similar problem as reported in the link below.

http://www.remoterig.com/forum/index.php?topic=1694.0

Although the power supply I am now using (Daiwa PS304) is working OK there have been the odd occasions where the FT-857 has locked up. I now have the FT-857 powered from the Daiwa PS304 and the RRC-1258 Remote powered from a seperate 2A 12V supply. Using DTMF control over the phone, I can remotely power on/off each power supply.
However, the ONLY way I can reset the FT-857 is to go to the remote site and connect the head-unit directly. Powering the FT-857 off and then on (whilst the RRC-1258 remains powered up) does NOT reset the FT-857.

Any suggestions appreciated although I will continue to investigate and report back any findings.

Hi Mike,
Thanks for the prompt reply and explanation. I searched extensively for these symptoms with the FT-857 but could not find it on the forum. Could you give the link for your previous explanation of this power supply issue. I am sure other FT-857 users will find this useful. In fact it may be worth adding a comment regarding this in the FT-857 section of the manual. May save others the pain  :)
Thanks again. An excellent product by the way - now all is working OK!

This post may help those with an FT-857 – I would also like to know why this problem occurs!
I have owned an FT-857 version of the RRC-1258 MkII for several weeks now. I have two separate ADSL Broadband connections into my home and I successfully tested ‘on the bench’ from the FT-857 head unit, via Remoterig across the Internet, to the FT-857 main unit. Round trip delay was approximately 60ms. On every occasion, the FT-857 successfully powered up and powered down remotely without hanging.
I then moved the FT-857 main unit and RRC-1258 remote unit to my remote location. Round trip delay across the Internet is approximately 50ms. Fortunately my remote location is only a short drive away.  On repeated occasions,  as soon as I pressed the power button on the FT-857 head unit, relays within the FT-857 main unit would activate but it would then ‘lock up’ (I know this because on several test sessions I was at the remote location whilst a member of the family pressed the power button back home!). As recommended by Microbit, I can remotely power cycle the FT-857 but this would NOT reset the transceiver. The only way was to connect the head unit directly to the main unit as in normal operation. The symptoms seen on the control RRC-1258 were a successful SIP connection (yellow LED full on) but no incoming audio stream (flashing red LED). I spent ages checking and changing everything (UDP ports, remote ADSL router, jitter parameters etc). As I work in networking I even connected a network analyser to check packet flows. I assumed that it must have been a network problem. The SIP packet decodes were showing missing ‘8V ON OFF’ status indications. The FT-857 and the RRC-1258 are fed from the same DC power supply. Although I didn’t see why this would be a power supply problem I changed the power supply – AND EVERYTHING WORKED OK!
I still can’t understand why this would make a difference. Both power supplies were measured and delivered 13.5 volts so no under voltage issue. The only difference between the two power supplies was that the ‘failing’ supply (an Icom PS85) is a switched-mode supply with an ISOLATED –ve supply (ie not bonded to the power supply chassis and mains earth supply) whilst the ‘working’ power supply (a Daiwa PS304) is a linear power supply with the –ve supply grounded to the power supply chassis and mains earth.  I tested this ‘on the bench’ back home as well as remotely and every time the Icom PS85 would result in ‘lock up’ of the FT-857 whilst the Daiwa PS304 was fine. I am glad all is working but any suggestions why this this problem occurs would be appreciated – particularly as the FT-857 and RRC-1258 are fed from the same DC supply, as recommended by Microbit.

Interested to see there is now an FT-857 specific version of the Remoterig 1258MkIIs. Although interested to use this with my FT-857 can it easily be modified back to the 'standard' Remoterig 1258MkIIs if/when I no longer want to use this with the FT-857?
Thanks

Hi Mike and Mitch
Thanks for the info. Looks like I should be OK across this 2km path - even though it is obstructed. Guess the only way is to try it! Mitch, what antenna do you use with those Ubiquiti Bullets?
Thanks

General discussion forum / WLAN 2km point to point link
« on: 2011-05-09, 18:09:30 »
I have not yet purchased the RRC-1258 pair as I need to be certain that I can establish a reliable link to the remote site. It is NOT possible to provide an ADSL Broadband connection at the remote site and I assume a 3G broadband link would be costly and/or provide unreliable/poor performance. The remote location is only 2km from my home location yet is across an obstructed (non line of site) path.  I have seen recommendations for the Ubiquiti (www.ubnt.com) Powerstation 5 and Nanostation M5 point-to-point WLAN products and these look like a good solution for paths of several kilometres or more. However, I would appreciate comments regarding the performance and reliability of a WLAN 2GHz or 5GHz link over this 2km non line of site path.
