Re: Speaker recommendation for lenovo laptop used with my SDR
I have two pairs of these Altec Lansing computer speakers:
https://www.google.com/shopping/product/1?q=altec+lansing+computer+speakers&prds=epd:5091007796436140768,eto:5091007796436140768_0,pid:5091007796436140768&sa=X&ved=0ahUKEwjnruymkeT4AhU9EmIAHc2jDAUQ9pwGCAk First pair I installed on my desktop, and sounded so good I dug the other pair out of the basement and placed it on the laptop (Super Station #1 Server) in my kitchen. I find myself streaming music from it when not roaming the bands on any of my SDRC Servers. Probably better stuff out there for real money, but these were either free from the white goods day at the local dump, or free on the side of the road after somebodies yard sale ended. The subwoofer makes all the difference in my aging ears. 73 Kriss KA1GJU Home of the Super Station SDRC Servers in NH, USA (FN42mw)

30 seconds plus a button that saves the last 30 seconds to a file might be nice. {o.o} On 20220705 23:33:37, Eric Inloes

Wires are inconvenient; but, they do remove some annoying potential problems. And if you are sitting at your ham station listening you're stuck there for your tuning knob so why no wired NOISE CANCELING earbuds? {o.o} On 20220705 23:03:46, Peter 1956 wrote:

Re: Speaker recommendation for lenovo laptop used with my SDR

PK - for pure important communications or contesting the old Motorola police or utility radios are, well, designed for speech and if that kills "fidelity" "oh well." If you want easy listening for extended rag chews or coffee table discussions something better is called for. For that anything from a modest external 2 speaker plus 1 woofer setup on up to top end HiFi both with an equalizer would at least partially knock off two birds with one stone. Another thing to consider is some comfortable noise canceling earphones such as what Bose, Sennheiser, Sony, and others make as traditional "cans" and ear buds. Getting rid of room noise (and echos) can often bring out higher intelligibility even without equalization. (i.e. consider a deeper dive into just what you want and will
tolerate.) {^_^} On 20220705 22:46:32, Mike wrote:

Hi Simon,

That is true. In most cases i figure 30 seconds should cover it. I see this being useful for say Meteor scatter on the FM broadcast band.

Speaker recommendation for lenovo laptop used with my SDR
Mike
Hi Everyone,
I was looking for a recommendation for a good communications speaker I can connect to my lenovo laptop. Seems the speakers that are in the laptop just don't perform as well as I would like. Thanks, Mike

Re: Cached data
Eric,
I'll think about this - 30 seconds should be enough, more than 1/8th or certainly 1/4 of the RAM and the cache will have to be written to disk.

Re: Lost cat control to external radio

Normally speaking a shared port would not communicate with each other but would both communicate with a third port. At least that is the way the lower level windows code is setup unless it has changed since Win7. I've seen no indication that this is the case. The standard serial concept is a data terminal (DTE) and a modem
(DCE) that use different physical pins for transmit and receive.
Special cables are needed to have two terminals communicate with
each other as opposed for one of them to communicate with the
computer. This is pretty much the RS232 model. There are the RS422
and RS485 which can or can be pushed into a telephone "party
line" multiple speakers and multiple receivers, on the same wire.
But, usually Windows thinks in terms of RS232, one DTE
communicating with one DCE with many of the "in" and "out" aspects
of the pin definitions being reversed. Hooking up 3 devices on one
wire means you grow burn out problems and communications problems. {o.o} On 20220705 17:29:42, Siegfried

Re: Remote encoder

almost you can use "F5" for tx ... so if you can programm a button to send "f5" ... then it does work
another option is to get a dj deck that speaks midi
works superb (see picture to see my midi deck settings)

Re: Lost cat control to external radio

i vspe you can use a "pair" of comports (see that as a cable with two different numbers on its end) or a "splitter" (shared port) or ... ?(many different settings possible in vspe .. to many to discuss them all here) ;-) yes a shared port would be sendng a command to more then just one terminal say you want to send a frequency to your rig, logbook, cluster spot software (and whatever) ... sometimes a shared port does help (in other cases not) or ... you have a cat soft that controls rigs qrg but ptt is done with a circuit on the rts pin (and not via cat command) ... alslo then a shared port (splitter) is helpful so ... it depends ;-) dg9bfc sigi ps remember a virtual port is a different thingy as a real port
... even if sometimes it behaves similar Am 06.07.2022 um 01:21 schrieb jdow:

Oh, and to see the External Radio settings click on the "?" on the External Radio window.

Re: Lost cat control to external radio

The interface between SDRC and Omni-Rig is an API only I believe. The only COM port setting for connection to your radio is in the Omni-Rig Settings:
That is the only place I have any COM port setting defined. I am using Omni-Rig version 1.19. It works fine so I see no reason to change. -- Dennis KA6FUB

Tools menu. Options. Take a tour. You will find all manner of
interesting things including com port selections for various
things. And your ideal source for help is, believe it or not,
https://www.sddr-radio.com and some small dab of exploratory
spirit as you wander through the menus leading to pages just chock
full of interesting help. {^_^} On 20220705 15:24:47, Cody via

Re: Lost cat control to external radio

I would think they'd have different COM port numbers. Two things
connected to the same COMn port would be the same as two terminals
connected together with a 1:1 cable rather than a cable that
twists R and T wires and the flow control wires. {^_^} On 20220705 14:06:51, Siegfried

Re: RDS decoding
Eric Inloes
Another factor is the signal level of the RDS signal. It sees to vary all over the place. Sometimes it requires an ultra strong signal to a decode.
No idea why there isn't a recommended level for it already.
