[AMRadio] To All that owe our career to the Gonset Communicator
This was sent from Bob Heil and is a great article about Gonset and that great old Gonset Communicator that we all started with.I had one as a novice and did not upgrade in the one year time that cost me 6 months to get my General. I also remember the CAP using these and the CD Yellow unit. Bob W1PE This is a fascinating article about Bob Gonsett and his father Faust Gonsett that help to create the excitement on the VHF amateur airwaves. Many of us learned so much from those early days of VHF experimenting and operating with those loveable little 'Goonie Boxes'. I still have several . I hope you kept yours and are using them ! Read on - another great career all founded upon amateur radio. http://www.rwonline.com/article/100300 BOB HEIL, K9EID (since 1956) 618 257 3000 http://www.heilsound.com www.heilsound.com __ Our Main Website: http://www.amfone.net AMRadio mailing list Searchable Archives: http://www.mail-archive.com/amradio@mailman.qth.net/ List Rules (must read!): http://w5ami.net/amradiofaq.html List Home: http://mailman.qth.net/mailman/listinfo/amradio Post: AMRadio@mailman.qth.net To unsubscribe, send an email to amradio-requ...@mailman.qth.net with the word unsubscribe in the message body.

Re: [AMRadio] Modulator question.
Hi Brian, Do you have a modulation scheme in mind? i.e., high-level, plate or controlled carrier or others While rolling your own can be done and certainly is rewarding when the whole magilla finally works...there might be other avenues to explore. For example, there are rigs like the Eico 720 when coupled to the Eico 730 modulator gives a pretty nice low-power signal. Back issues of Electric Radio have one or two articles addressing this lashup. The fairly common Heath DX-60 family of AM/CW transmitters provides a good base for some nice AM signals when used with an ordinary linear amplifier. Done up right, they sound might impressive. Again, some nice Electric Radio articles address the finer points. But there are also opportunities for low-power AM rigs to be found in older ARRL handbooks and Bill Orr's publications over the years. Pick your tube, design the power supply and the rest is relatively simple. Just thinking out loud with you. Others may have more/better ideas. But accomplishing what you desire is not that difficult. Let us hear back from you. May be able to steer a particular design your way. 73 Chuck W4MIL -Original Message- From: Brian Zwiener bzwie...@sbcglobal.net To: Discussion of AM Radio in the Amateur Service amradio@mailman.qth.net Sent: Fri, May 7, 2010 4:49 pm Subject: Re: [AMRadio] Modulator question.

Re: [AMRadio] Modulator question.
Have you considered using a car audio amplifier in a cathode modulation? If possible it could avoid finding another transformer that would stand the higher voltage and current in a plate arrangement.

Re: [AMRadio] Modulator question.
Talk with Jim (WD5JKO), I think he has used a Crown P.A. amplifier as a cathode modulator, maybe an SB-200 as the final? Unless you're stuck with 13.8 VDC, I would look for something in the commercial P.A. type amps.(Guitar Center,Musician's Friend, pawn shops,etc.) I have a 45 year old Fender PA-100 with 4 6L6's in Push-Pull, that is being converted into a modulator for a pair of 807's, the RF deck and power supply are done.
