No radio <br>> marketed to the amateur market does. Kenwood kind of came close at one <br>> time. The Motorola Micom-H would as it was a micom-2 with different <br>> controls. This has been my "thing" for a while. I had an HF remote way <br>> back and the lack of proper squelch was hard on the UHF PA tube, <br>> sometimes keyed up for three hours straight.<br>> <br>> But no plug and play way to control the non amateur rigs out there.<br>> <br>> So my next one, in the works, will have proper squelch. And it isn't an <br>> original idea. As far back as 73 magazine in 72 or 73 there was an <br>> article to build what essentially is the Motorola Micom squelch from the <br>> earlier days when it was all discreet transistor circuitry, but the <br>> article used IC's. And it works. I made a PC board for it and found that <br>> someone else had done so a few years earlier but they were now <br>> unobtanium. I have a new board that refines it quite a bit more (fewer <br>> parts, same function). I have not yet had this board made, have to wait <br>> till Chinese new year is over to get them made. I made this particular <br>> one to fit in the space within a FT-857D where the optional filters <br>> would go.<br>> <br>> I also just moved and do not yet have my workshop set up.<br>> <br>> If you want I'll keep you posted or I'll post here when it is done. HF <br>> radio needs this and why a company like ICOM can put it in their marine <br>> versions and not amateur makes no sense, same for Yaesu.<br>> <br>> Also, if you can come up with a junker Micom (pre-synthesized) with plug <br>> in PC cards, one will be a squelch card that can be adapted very easily.<br>> <br>> The BF-888 is pretty nice for the purpose but they also sell a BF-U3 <br>> which I have a couple of. Seems like a different board but I have <br>> already scoped the BF-8U for interface, with the thought of its use as a <br>> "micronode". But for a repeater it's going to fall short in performance.<br>> <br>> GeorgeC<br>> W2DB<br>> Toms River, NJ<br>> 2360 (Allstar)<br>> 2428 Allstar remote base (off the air)<br>> <br>> ---------------------------------------------------------------------- <br>> Message: 1 Date: Mon, 8 Feb 2016 16:55:11 -0500 (EST) From: David <br>> McGough <kb4fxc@inttek.net> To: ARM Allstar <arm-allstar@hamvoip.org> <br>> Subject: Re: [arm-allstar] Newbie AllStar Message-ID: <br>> <Pine.LNX.4.44.1602081624120.31261-100000@goliath.inttek.net> <br>> Content-Type: TEXT/PLAIN; charset=US-ASCII Hi Danny, Good to hear from <br>> you! We've talked over on the 145.41 repeater via echolink in <br>> Wilmington, NC. Yes, the AllStar software will allow you to use a single <br>> computer, either a full PC, a Raspberry Pi 2 (preferred) or Beaglebone <br>> Black to accomplish AllStar connectivity and echolink, etc. As for an HF <br>> remote base, I don't believe the TS-480HX implements an SSB syllabic <br>> squelch signal??? For an SSB HF radio, you need some method of <br>> generating a COS/COR (carrier operated switch) signaling if you wish to <br>> use the HF rig with echolink (this is due to the echolink half-duplex <br>> design)....With AllStar, which is full-duplex, the SSB COS/COR is <br>> optional, but, still -very- desirable. The TM-D710 radio will work fine <br>> as a simplex node on AllStar. Or, for short range use, a pair of Baofeng <br>> BF-888 UHF radios can be used to make a full-blown repeater---all <br>> hardware purchased new (including the RPi2, power supplies, etc.) for <br>> under $100! (See the bottom of this page for my first prototype: <br>> http://crompton.com/hamradio/baofeng888/ )...Note that I've run these <br>> 888 transmitters at continuous duty cycle for HOURS at the time with no <br>> issues--incredible for a radio in the $15 range! See the <br>> http://hamvoip.org website for more details. 73, David KB4FXC On Mon, 8 <br>> Feb 2016, Danny wrote:<br>> >> Hi guys,<br>> >><br>> >> I am new to AllStar and have read a lot about it ... a friend of mine<br>> >> recommended I have a look at AllStar since I already have an EchoLink node ...<br>> >><br>> >> I am running Debian with SvxLink as my EchoLink server ...<br>> >><br>> >> One of my goals is to cross-band repeat my EchoLink (2M) node to HF (40M) to<br>> >> enable me to RX/TX longer distances and to help local Hams who does not have the<br>> >> finacial means to have international QSO's with simple/older/cheap radios ...<br>> >> all they have to do is to make sure they can reach the antennas at my QTH ...
