Re: [Flexradio] Direct Conversion White Paper

Gary I strongly suggest using an outboard DSP filter on the audio. The Flex radios are great receivers and will bring in signals at the noise level, but once you get to the noise level you can use a DSP audio processor to help reduce the background hiss. I use a BHI NEIM1031 unit that is ver

Re: [Flexradio] Flex 5000A on AM

I've been on AM with the Flex 5000 for quite awhile. Always get great audio reports. Mike is a hand-held type from some old Yaesu FM transceiver, No multiple audio boxes between it and the rig. The various audio controls are adjusted as described in the manual. RF sampler with an diode output allow

There is no level setting or on/off switch for pre and de-emphsis in FM. It is on all the time. Tim Ellison, W4TME Product Management, Sales & Support FlexRadio Systems^(TM) 4616 W Howard Ln, Suite 1-150 Austin, TX 78728 Phone: 512-535-4713 Ext. 223 Email: t...@flexradio.com

Re: [Flexradio] Flex 5000A on AM

I may be naive, but all I do is push the AM button, using my standard 'SSB polished' audio chain, and get unsolicited 'hey, you sound like a broadcast station' reports. > Date: Wed, 29 Feb 2012 18:10:46 -0500 > From: w1...@optonline.net > To: FlexRadio@flex-radio.biz > Subject: [Flexradio] Fl

[Flexradio] Flex 5000A on AM

I will simply add that I've been operating my Flex 5KA on AM since I got is over 3 years ago and get nothing but compliments. Use a carefully tuned audio enhancement system, don't overdrive, throw in a classic 60 year old RCA 77DX ribbon and you get a superb result. I am very happy with my Flex on

I am unable to locate any info on FM audio, such as Pre-emphasis/de-emphasis level etc. I accept that it may be due to senior moments etc. but a little direction would be helpful! Jim W4YXU ___ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz h

Re: [Flexradio] Damage control - "designed for AM" ?

The best way to set up an AM transmitter, be it a Viking II or a Flex 5000A is to have a dummy load with an rf sampling coupler, an oscilloscope and an audio signal generator. With this equipment, you can set up an AM transmitter and leave all the settings alone. However, most radio amateurs d

Re: [Flexradio] Damage control - "designed for AM" ?

As I LOVE AM. 20+ years ago I used to be a part of a weekly 160 meter AM roundtable QSO. If someone could put together a nice knowledge base document on setting up the Flex for optimum AM experience, I would appreciate. 73, Robert KB6QXM "Ham Radio Open Conversation" Yahoo group owner/moderator

Re: [Flexradio] Damage control - "designed for AM" ?

I apologize for not following this thread and just stumbling onto this last message, but I thought I would add my 2 cents about AM operation. I have been using the Flex5000A for over a year and a half on AM. I set things up with a scope and the Flex can be adjusted perfectly to meet full AM sp

Thanks for the clarification, Bob. The rumor mill is a bitch and, of course, there is a small cohort of Flex-bashers lurking out there, eager to pick up on anything they can use to trash the products. On Wed, Feb 29, 2012 at 8:01 AM, Robert McGwier wrote: > Let me state for the record that in

Re: [Flexradio] Damage control - "designed for AM" ?

Let me state for the record that in writing the DSP code in DttSP, no mode has received more thought or effort than AM except CW. I worked very hard on SAM, and I worked very hard thinking through and implementing "synchronous carrier added DSB " which allows very large modulation index compared

Re: [Flexradio] Damage control - "designed for AM" ?

SMOP Of course. And I'm not interested in making it into any kind of issue, either. It just goes to show how sensitive people can be to the way things are phrased, and how statements get repeated down the chain. (even out of context) I agree completely and will repeat that Flex rigs work ve
