Banquet Reservations

Robert Bereit
 

The Skyview Banquet will take place at the Delmont Fire Hall on Saturday, January 25.  See the attached notice for details.

 

To allow sufficient time for the officers to plan for this event, we ask that reservations be made by the January Business Meeting, which is this coming Tuesday, January 7th. You can turn them into me at the meeting, or mail them as instructed in the attachment.

 

See you at the Banquet!

 

Bob, K3RMB

Train trip details!

Robert
 

Happy New Year all! 

The ARRL train trip information file has been uploaded to this io group. (It's in the Files section) It is a PDF with the name 2020 ARRL train trip details. 

Download and look it over. There are step by step instructions on buying the train tickets. 

Important points:
- Buy your train tickets and make your reservations early. Give it a day or two to make your hotel reservations, however. I have a signed agreement with the hotel that I just returned today - So with the holiday and all it won't be official until they receive it. 

- You must let me know that you made your reservations AFTER you are finished. radiofreebob gmail . com. So even if you already told me you are planning on going, please let me know again after you are all set up. I need to know how many people are going to know how many cars need rented. 

If you have any issues please let me know ASAP.

Re: IC-7300 question about IP+

Dave Mueller AA3EE
 

Not even close enough for IP+ to make a difference.  The stronger signal needs to be many (like 50) dB over S9 before the receiver front end will overload and generate artificial noise and distortion.
IP3 doesn't actually apply to SDRs, but overloading an RF stage has the same symptoms in any case.

The last sticking point of the ARRL train trip has been getting to the hotel in New Haven Thursday evening from the train station, and back to the train station Saturday morning in time to return home. The La Quinta hotel looked very promising as they had a shuttle that could do what we needed. The problem arose when the manager of the hotel won't call me back, e-mail me back, anything back. After using a couple Italian swear words I gave up on La Qunita. I gave them every chance. 

I found another hotel near by that also has a shuttle. The manager does call me back. She tells me that our plan should be no problem. She is willing to do a thing where folks would simply ask for the "The Skyview deal" and everyone will be on the same page. The only thing is that the price is higher, on the order of @ $115 a night (2 nights). I think it's a good deal. It looks like a very nice place. Unless there are any objections I will make it a solid deal this week.

Re: IC-7300 question about IP+

Harry Bloomberg
 

Haven't had my IC-7300 in a contest yet, but I will keep this in mind.  Thanks!

One area where the IC-7300 is far ahead of the IC-7200 is noise reduction.  With just a small amount of NR on the IC-7300, CW signals just pop out of the background.
