[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,

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

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.

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)

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

[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

Hi, Which build of DM780? There was a bug which is now fixed. Simon Brown, HB9DRV www.ham-radio-deluxe.com - Original Message - From: ac0mj ac0mj@gmail.com 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

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

[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

Re: [digitalradio] DM 780 Drift

- Original Message - From: mikea mi...@mikea.ath.cx I'll bet that you have AFC turned on, and that the frequency is drifting because of AFC. There's an option in DM780 to show the RF frequency + AF frequency, does this make sense? In the v5.0 betas it's in Tools, Program Options,

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

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

I use FLDIGI 3.1 for Linux, I set it up for RSID. I get nothing, all decoding stops. Is this normal? or did I miss something. I also noticed the waterfall speeds up significantly Thanks Dan kc2sta Not sure what's going on there Dan. The windows version works fine with the RSID. Skip
