Re: [Elecraft] Original Bandmaster and K3

I have set it up in what I believe to be a correct manner, with the radio set to Yaesu, the interface as RS-232 and the baud rate to 9600. If you are using a serial connection, set the Bandmaster for *KENWOOD*. The Elecraft protocol is nearly identical to that of Kenwood. In fact, I often

Hey Santa, where is my K3 / 0 Mini, how did I write about it? Why again do hot socks and deer sweaters like every year? Guys, is there someone who would like to make me happy with some good offer? I pay thru PayPal and shipping to the EU No trades for socks and sweater, I'll

Re: [Elecraft] K3s SSB transmitting bandwidth?

Just made a quick sweep of my K3S in DATA A mode, no EQ, No SP, and find that it will pass 70 Hz with little to no attenuation. On the high end it will pass 3000 Hz but greatly attenuates 3100 Hz.  This is done with the stock filter of 2.7 kHz. At this point in time, I don't have a suitable

I have recently come into possession of an Array Solutions Bandmaster, the *original* edition. I have set it up in what I believe to be a correct manner, with the radio set to Yaesu, the interface as RS-232 and the baud rate to 9600. The radio baud rate is set correctly to 9600 also. In

Michael, There are curves of the filter response on the Elecraft website - but with the new website, I cannot give you a link, things have changed. 73, Don W3FPR On 12/25/2018 12:10 PM, Michael Blake via Elecraft wrote: Bob, good information as was Don’s response but I am looking for a

[Elecraft] K3 Macro

Here's something to ponder over a belly full of Christmas dinner: How do you program a long hold into a macro? I'm wanting to place the K3 into "live" scan, a long hold of the scan button. I can do a SWH41, it works for scan, but no audio! Have a great Holiday. -- Carl AB1DD Resistance is

Re: [Elecraft] K3s SSB transmitting bandwidth?

The cutoff would be higher than 2.7kHz. What you add to the high frequency end is subtracted from the low end. The high end is normally about 3kHz which means the low end of the roofing filter is at about 300Hz. Yes, ESSB operation would require the 6kHz roofing filter. 73, Don W3FPR On

Re: [Elecraft] [Elecraft-K3] K3s SSB transmitting bandwidth?

Bob, good information as was Don’s response but I am looking for a specific piece of information relative the actual response of a K3s on SSB using the stock 2.7KHz. filter and zero TX equalization. Michael Blake k9...@mac.com > On Dec 25, 2018, at 12:05 PM, W2XJ

Re: [Elecraft] K3s SSB transmitting bandwidth?

The rule for a balanced sound is that the product of the lowest and highest frequency should be between 450,000 and 500,000. So for a 2.7 KHz cutoff that means a low cut of 166 to 185 Hertz, or rounding that could be 200 Hertz. Sent from my iPad > On Dec 25, 2018, at 8:03 AM, Michael Blake

Thanks Don. The published curves ( https://elecraft.com/pages/k3s-8-215-mhz-first-if-crystal-filter-response-curves ) suggest that there will be significant low end rolloff below 300 Hz. But I have not taken

Re: [Elecraft] K3s SSB transmitting bandwidth?

Michael, I think the rolloff is not much (in support of those who want ESSB operation. Much of the rolloff depends on your microphone. Jim Brown K9YC has long advocated reducing the TX EQ below 500 Hz or so in order to increase your effective communications power. An improvement of 3 dB or

Hi Gareth, Here are a couple of documents showing how to set up the KPA and KAT and how the KAT works. http://www.ke7x.com/home/k-line-introduction-and-set-up-guide Also, "The KPA500 and KAT500" (the K-Line book) has more information on interfacing Icom radios but the basic band switching is

Re: [Elecraft] Using the KAT-500 and KPA-500 with Icom rigs

Gareth, Elecraft has developed cables for the Icom, Yaesu, Kenwood, and Flex transceivers that make the KPA500/KAT500 Power combo "Play Well With Others". I don't know the specifics of the cables, but I do know they exist. The KAT500 manual has pinout information for cables to use with the

This has just come up in my RSS feed. https://kg3v.com/2018/12/24/using-the-elecraft-kpa-500-and-kat-500-with-icom-rigs-part-i/ I’ve not seen this being discussed on this list, so perhaps somebody with knowledge could help the OP out. Happy Christmas -- Gareth M5KVK
