Re: Have you bought from Quick Silver Radio?

Rowland
 

My son Jesse is needing some LMR400 and RG8X.  Is the UF more expensive than the regular LMR400?


Thanks,

Rowland

VARA and Winlink

Paul Butzi (W7PFB)
 

Motivated by the Weekly Net check-in via Winlink I have been experimenting with Winlink again.

In particular I was interested in what changes happen as a result of the abandoning of the Winmor connection protocol/modem/soft TNC.

The direct replacement for Winmor is ARDOP. I have used ARDOP for a while, it is more reliable and perhaps a bit faster than Winmor but not a dramatic improvement.

So I decided to try VARA.

The downside of VARA is that if you want it to go into fast mode, and you want to avoid the nag screen, you must buy a license, which costs $70.

The upsides are:

* VARA is faster, especially in good conditions when you can run a fair bit of power on your end (most of the Winlink RMS stations seem to run pretty solid signals). On a really solid connection, VARA is massively faster.

* In any conditions that are less than ideal VARA is dramatically more reliable and faster than any of the non PACTOR alternatives. As PACTOR TNC’s cost more than $1k, that makes $70 a pretty good deal. (I don’t own a PACTOR TNC so I don’t know how the various PACTOR modes stack up against VARA)

In short I can connect to more Winlink RMS stations using VARA than I can using Winmor or ARDOP. I can connect more reliably when conditions are not optimal. I can connect reliably using 5-15W instead of 30-70W. And the connections are faster.

In short, I think it’s a pretty interesting piece of technology.

And that’s all on HF.

There’s a version of VARA for VHF/UHF FM which can exploit the wider audio bandwidth you get when you use the 9600 baud receive data path of a VHF/UHF radio that offers input/output for a 9600 baud packet modem.

This would get around the big problem with VHF/UHF Winlink, which is that packet radio is deadly slow. The slow speed of packet is the flaw that makes VHF/UHF Winlink nearly useless for tactical use in an emergency. There are other problems with VHF/UHF Winlink but the flaw that cannot be ignored is that it is just too darn slow for modern needs like moving digital photos or larger files.

I’l be ordering some hardware to allow me to exploit the wider data path you get using the 9600 baud audio path - basically a couple of wide bandwidth sound cards.

Is anyone else interested in experimenting with experimenting with VARA on VHF/UHF FM? If so, let me know and we can coordinate.

Also, if you’re a Winlink HF user, I urge you to check out VARA. The evaluation copy, speed throttled as it is, is still a dramatic improvement over Winmor and ARDOP, especially in marginal conditions.

I’ve bought from the before when I was building my radio go box. No issues here.

Interested in an ICS-300 class?

Rowland
 

This has never been offered online before.  I suggest taking it if you can.
Rowland

 


 

 

Hello!

The emergency management 'Training & Exercise' folks across the state are preparing to deliver ICS-300 classes via video conferencing. We would like to get some feedback from our potential students on what your needs and preferences are. Please help us by answering three quick questions.  (This should take less than a minute.)  We will forward the results of this survey to the County you identify in the survey.

Here is the link to the survey: https://www.surveymonkey.com/r/ICS300-interest 

Thanks for your help with this!  (And feel free to forward the link for this survey to *anyone* else (in your organization or elsewhere) that you know may want to attend an ICS-300 class in the next 6 months.)

Best regards,

  Eric

The Mixer is yours…

For what you describe you would want to add an XLR switch along with the mixer. I have one mic - I use the switch to pick which rig (or my PC) I want to direct it towards. I also have a foot pedal that is controlled by the switch. So if I select “Y", for instance, that’s my FTM-400 - the foot switch is directed to activate that unit and the mic flows into the mixer which distributes the sound. Output from the rigs flow back into the mixer and are distributed to my headphones and external speaker. 

Here is the switch I use

I am happy to let someone else snap the mixer up but I’m super interested in how you have this set up in your shack and what sort of stuff it does for you.

I’ve been pining or a way to have multiple mics in my shack and having some way to connect any particular mic to any particular rig.  And a way to route sound from any particular rig to any particular headset or set of speakers.

So if such a mixer can be used to do that, I’d love to learn how!

Hello fellow Snovarcians,

I have a brand new Mackie Mix 8 mixer that is still unopened in its box (actually it's still in its unopened UPS shipping box). 

Mixers are great for connecting, for example, a single microphone for use with multiple rigs. They're also very useful for directing output from multiple sources to speakers as well as headphones - each with their own gain and filter controls. There are a ton of other uses.

This mixer is free to anyone that wants it that fits one of these criteria 1) you are retired, 2) you are a student, 3) you just really want it. 

I'm glad to drop it off if you meet me in the Duvall/Carnation/Redmond/Woodinville area.

My Yaesu 400 has an altitude indicator. That is a great correlation with signal strength I’ve learned.

It would be wildly cool to do the same with HAM radio crews.
