Re: No radio hooked up

Monte Stark
 

Hi Joe,

 

Sorry for the delay but we were off doing the turkey day things with the family up in Boise. Got back last night and woke up to a bit of snow here! But it is winter so I can't complain. And the 5 acres looks some much nicer when all the weeds are hidden under that white stuff.  :-)

 

It turns out that the two folks who needed the info figured it out by themselves. And one of them has a 7200 that he is trying to get set up with the computer. Neither have a keyer that works with computer control so they will still be hand sending until they come up with something like a K1EL keyer.

 

Thank you very much for your offer of help. It is very much appreciated.

 

OK, back in my hole,

I am trying to help a new to N1MM+ op get set up. The radio is a little QRP
rig with no way to connect to the program. For the life of me I can't
remember how to set it up. There is also no keyer at this time either.
Sending will be done by hand.
 
Thanks for any ideas.

Re: missing spots in window [Available Mult's & Q's] ?

VE9AA - Mike
 

Saki, 
For your K2WK spot, it's probably just below the bottom of the window if you scrolled up one tiny notch past in3fhe (your window is holding more spots than you can visualize/see).

For your comment about German stations. They are worth 0 pts and after the very very first Germany QSO in (presumably) the first hour (if you were QRV), there is no point in working your fellow German countryman. (0 pts, is 0 pts....I had Canadians call me all weekend and I have to assume they just got on the air and needed their first Canadian contact for the country mult.)

I am not a programmer, but my first inclination (just a guess...not sure) is maybe you had already worked ZD7W & VK9CZ on that band already?

The 2nd guess was that you had it sorted by time and one other parameter and they are not showing in the visible screen area.  I can't see all your columns, so I am not sure what that would be.  It's definitely time, but the 2nd parameter does not appear to be beam heading, alphabetical or frequency.

When contests like CQWW take place, there is no way to display 100% of all the mults and Q's available, so at times it's better to only display mults, until you get them cleaned up a bit, and only then go back to trying to display all. 

Sorry - only a couple ideas. Hopefully others will also have some.  I rarely sort the mult window so I don't even know which columns are missing (if any) or that I can't see.

Re: 7300 Question

Lane Dossett
 

Gents, 

Thanks to all who responded. Indeed, it does appear to be an RFI issue.  I have now determined that I only experience the com port error when using my tuner. N1MM works flawlessly when I bypass the tuner or use the tuner below 20 watts.  I had used other programs for digital operation at 100 watts, so I just assumed this was an N1MM issue when I switched over to using it for CW, but I'm sure the concentrated CW put out by N!MM creates higher RFI than, say, FT8 or PSK, etc.  Thanks to again. Hope all had a Happy Turkey Day. 73 de N5AAS

Re: 30% off Airspy HF+ this week

Jamie, 

RSPdx may a better comparison than the RSP1A to AirSpy HF+ since both cover HF frequencies although the RSP1A also covers HF too.  

Curious about your opinions on the two units?  

AirSpy HF+ covers limited frequency ranges:  0.5khz to 31Mhz on HF and 60-260MHz on VHF

https://v3.airspy.us/product/airspy-hf-discovery/ 

SDRplay RSPdx covers 1 Khz to 2 GHz with more antenna ports but costs more than the HF+

https://www.sdrplay.com/rspdx/ 


RSP1A cost less than both even with AirSpy's sale.

Thanks for your info on AirSpy's SDR sale.  

Been trying to decide between SDRplay's RSPdx (coming out soon) and the AirSpy HF+ Discovery for RFI searches and tracking, and with sale price and availability; now leaning toward AirSpy unit.  

Anyone know if ARRL or anyone else has already done a technical comparison either of these SDR units or others?

I experienced that problem at about 50 watts on my 756 Pro III when the Winkeyer would lock up. Turned out to be RFI which got into the cables. Solved the problems by putting large ferrites at the cable ends and wrapping 3-4 turns of cable through the ends. Did the same thing with my new 7300 and haven’t had a problem. You might try this. Best of luck.

Re: Sending CAT commands from non function keys.

Tim,

 

These control buttons are inherently rig independent. Each button has a user defined legend and user defined script based on the existing CATxxxx Macros - exactly the same methodology used for implementing the rig control buttons in the Bandmap window.

I'm not opposed to adding more functionality to N1MM in terms of rig control or amp control or antenna selection control.

 

HOWEVER, doing very rig-specific or station-wiring-specific functions via buttons in a generalized N1MM GUI seems like an extraordinarily poor way to do this for a contester.

 

Look at how bad (I mean, just point-and-drool bad) GUI's for SDR's were until K9CT showed them how to do it right.

 

All of these requests seem to be incredibly rig-specific or station-wiring specific. And at least some of the true automation (not point-and-drool GUI) requests might be approached by scripting outside N1MM, possibly using UDP broadcasts already available from N1MM.

I added another button and programmed it so it allows me to toggle between FIL1, FIL2 and FIL3. Of course you could reprogram the default existing NAR/WIDE button so it switches between FIL2 and FIL3, but I liked to have the option to toggle through all the three filter presets.

button 3:

Re: Sending CAT commands from non function keys.

John H. Long Jr.
 

I was hoping for a more generic ability to add our own custom set of CAT commands.

One application is for a Elecraft K3.

A more flexable one for me is to add CAT commands for new radios, IE: Xiegu G90.
Their CAT command set is still not finalized.  It would be nice to add our own set of CAT commands as they are developed.

It may be a while untill they finalize and publish their final CAT command set.

Tom, I can appreciate why you would not want to add more rig control buttons onto the Bandmap window - that window gets very busy in many contests. Which is why the concept of a new 'Rig Control' window seems attractive. To save screen real-estate perhaps it could have a variable number of command buttons similar to the variable number of message buttons in the 'Digital Interface Window'. Finding and updating settings on modern radios through menu items on a touch screen in the middle of a contest really is a pain, especially when it could be done with a single mouse click.

Thanks in advance for considering this request & 73

Hi Lane,

sounds like you have RF in the shack as already mentioned. You can check that easily be reducing your transmit power to minimum (10% or even 0% on your IC-7300 which still outputs some watts). If the issue is gone you know for sure it's RF in your shack.

I would also suggest the Fair Rite 31 material, you could choose the clip  for 10.15mm and make 2-3 turns or more (whatever fits). I bet one clip is enough to cure the issue. Good luck and have fun!

Re: 7300 Question

John Bednar
 

Lane,

 

This is not unusual when there is RF in the shack. Your installation seems to be excessive.

 

Are you using a tuner or ladder line in the shack?

Is the antenna close to the radio?

Is the radio connected to a good ground?

 

Make sure your USB cable is shielded.

I would place a type 31 ferrite at the radio and a second at the computer. Wrap the USB cable at least three turns in each of these ferrites. If it is a clip on type, make sure the surfaces of the ferrite half’s are making good contact for the entire surface.
