[digitalradio] Possible Purchase
Hi All, I am in the proceeds of purchasing a new piece of radio equipment. I am tossing up between buying a new radio, new screwdriver antenna or a new sound interface. The first two are a lot more then the last. But that depends on which one I decide to buy. I had a look at the Rigblaster Pro, but at US$299 I felt this was a little high (I could be wrong here) I also looked at the Tigertronic at around $100 (a bit better price) My interest is in using it with my TS-480S/AT and any future rig I decide to buy. I am using all the digital modes. I would like it to be used on a couple of radios but that is not a high priority. I know this is very limited but what else is there to the interface. Some I have heard have better filtering and protection. Any thoughts would be grateful, direct would be fine too, see my address in the header. Regards Kevin, ZL1KFM.

Look at the microHam USB Interface III - soundcard and CAT in one package, I have one and use it with my own TS-480SAT. http://www.microham-usa.com/Products/USB3.html Simon Brown, HB9DRV www.ham-radio-deluxe.com - Original Message - From: Gmail - Kevin, Natalia, Stacey Rochelle I had a look at the Rigblaster Pro, but at US$299 I felt this was a little high (I could be wrong here)
Re: [digitalradio] Possible Purchase
Thanks Simon, But the big issue is the price. This one you mention is also up in the US$200 area, which is nearly NZ$400 for us, exchange rate. Makes me think twice before I purchase. I think I will get a sound interface it's just twisting my arm a little more to finally do the bank transfer. Regards Kevin., ZL1KFM BTW, version 7 is working great for me. Had one issue with DM780 shutting down when going into TX mode. Might of been because the network link was not active between it and HRD. - Original Message - From: Simon (HB9DRV) To: digitalradio@yahoogroups.com Sent: Sunday, July 12, 2009 9:34 PM Subject: Re: [digitalradio] Possible Purchase Look at the microHam USB Interface III - soundcard and CAT in one package, I have one and use it with my own TS-480SAT. http://www.microham-usa.com/Products/USB3.html Simon Brown, HB9DRV www.ham-radio-deluxe.com - Original Message - From: Gmail - Kevin, Natalia, Stacey Rochelle I had a look at the Rigblaster Pro, but at US$299 I felt this was a little high (I could be wrong here)
Re: [digitalradio] Possible Purchase
I continue to be puzzled as to why anyone would spend more than $50 on a soundcard and/or CAT interface, when both can be built for about $10 in parts. For the sound interface: * two 8:500 audio transformers * one 2n3904 transistor (for hard keying, if you don't want to just use the rig's VOX) * one DB-9 female connector * one 3.5mm audio patch cable (cut in half) * one mic or DIN connector * one altoids tin For CAT: * two 2n3904 transistors * five resistors (3x10k, 4.3k, 11k) * one DB-9 female connector * one connector suitable for your rig * one altoids tin The soundcard interface is nothing but the audio in/out lines from the rig connected to the soundcard with standard audio connections, optionally using transformers, and a single NPN transistor configured thusly: Collector: rig PTT pin Base: computer serial port RTS pin (DB-9 pin 7) Emitter: ground pins on rig and serial port CAT/CI-V interface is just two NPN's and 5 resistors. Google for schematics. Since I've never seen a rig that uses RTS/CTS handshaking, you can combine keying and CAT into a single serial connection. If you need USB audio and serial interfaces, they aren't too expensive. Don't know about sources in NZ, but they can be had in the US for as little as $5 each. -Joe, N8FQ On Sun, 12 Jul 2009 21:48:54 +1200 Gmail - Kevin, Natalia, Stacey Rochelle spar...@gmail.com wrote: I think I will get a sound interface it's just twisting my arm a little more to finally do the bank transfer.

Not everyone can see well enough to solder, not everyone has easy access to all the components. When I was starting in Ham Radio I built everything, now the only reason I use the soldering iron is for assembling cables, sadly the eyes no longer have what's needed.

Re: [digitalradio] Possible Purchase
See page 30 of the June QST for an inexpensive interface design and circuit board. As of this date, 250 have been built and all worked without any problems as far as I have been told. No SMT parts are used, and soldering is easy, even for an old man like me. Cost of all parts is less than $20 and no USB or serial port is needed.

[digitalradio] DM 780 Drift
Good Morning to the group, I have a question about the drift in Digital Master 780. I am sending out CQs in RTTY this morning on 20m and noticed as on other modes in the past that the signal I send drifts to the right slightly over time. I started on 14.084.10 and a half hour later I am at 14.084.35. I realize this is a minuscule drift, but I was wondering why it is happening. Thanks, AC0MJ

Re: [digitalradio] Possible Purchase
As was mentioned, construction may be impractical for many hams. In my case, I have been soldering since around age 13 or so with my first crystal radio kit and later many kits and dozens of projects over the years, so it is not too difficult to make a simple interface. Today, because of my age, it is increasingly difficult to do close work without special help. I normally wear trifocals and the close-in distance is for book reading at around a foot, but it is very much at the bottom of the glasses and difficult to use so I sometimes use magnifying googles. Due to an error in having some bifocal computer glasses made, with computer on the main portion and the full lower portion for reading, it turned out that they cut the lower part so that the focus was more like 8 inches. This actually slightly magnifies things but the downside is that I have to work extremely close to the work which also means that I need to be careful with any solder splashes, etc. Speaking from personal experience, one should never solder without eye protection as I have had splatter several times, which would have been catastrophic without glasses or some shield. I might mention that for about 25 years I built and ran an electronic/AV/computer repair shop, so exposure was significant. The largest project I ever built was the Heath HERO robot, which was a very large undertaking for educational use through my employer. Realistically, most new hams do not do construction of electronic projects and many no longer own soldering equipment, so it is actually quite rare to find those who are both interested in such things and also interested in the communication aspects (much less the digital communication aspects) of ham radio. If you don't need full rig control, and can build the simplest possible kit, I recommend the Unified Microsystems SCI-6 Sound Card Interface at just over $30 delivered price here in the U.S. It would be difficult to build it from your own separately purchased parts at that price point. It includes both audio lines transformer isolated, which is not always true of other products, and it has a socketed optoisolator for PTT hard keying. It does require a COM or USB to COM port, however that may be preferable to VOX keying. The most difficult part is making up your own cables, and that may not be easy for some to do. 73, Rick, KV9U
[digitalradio] Re: DM 780 Drift
I downloaded the newest version last night: Digital Master 780 v5.0 Beta build 2260 Since my last posted I am now drifted to 14.084.40 on DM 780. However, my frequency on my rig still reads 14.083.00 so I know my freq has not changed, but DM 780 shows other wise. --- In digitalradio@yahoogroups.com, Simon \(HB9DRV\) simon.br...@... wrote: Hi, Which build of DM780?

There's an option in DM780 to show the RF frequency + AF frequency, does this make sense?

Re: [digitalradio] Possible Purchase
If you do not have to have an external sound card the various interfaces that use your computers internal sound card are much less expensive. With some, such as the Rascal GLX you switch cables to use them with different transceivers. There are many other choices, I just happen to be familiar with that one.

Re: [digitalradio] Possible Purchase
For many reasons I built my own and I feel it is foolish not to use an optocoupler when you already use two transformers. I am not happy with less than that. I use soundcard input and output with stereo miniplugs and serial port keying with a DB9 female connector. I use another female DB9 for audio I/O, wired to the same standard as Kantronics TNC's, so my old TNC cables are still useful. All using scrounged material, and does work acceptably well. I have included fixed attenuators in the newer cables to suit the radio, so the interface is the simplest. Of course, I understand all the explained reasons, but in my case, homebrewing is the easy way out. 73, Jose, CO2JA.

I imagine you could easily display a good 10-20x image of the work on your monitor (perhaps with the aid of an external lens). That's a lot of magnification and as a bonus you can sit straight and not spend hours hunched over your desk looking at the work with magnifying goggles on. You also inhale less flux fumes and avoid solder splashes. -- 73, Stelios, M0GLD.
