SB XXX product proposal, other VFOs, Freq Counter

[Fred Finster]

     In reference below to the SB XXX product query, maybe these 3
     suggestions would be a solution to that drift problem for the SB line.


     Are there other suggestions out there to build a SB XXX product.  Here
     is my two cents worth to answer that question.   Maybe use this 1st
     product and add the Cake Pan 5 for the glow in the dark visual effects
     and get 5 watts Cw to boot or 1 1/2 Watts glorious AM phone on 80
     Meters.   That would be a Good SB xxx replacement product. Stability
     for frequency control using Solid State and easy clean Vacuum Tube
     Transmitter power output.   Since Heath made model 100, 101, 102, 103,
     104, 301, 401  maybe this proposed product could be named the SB 501
     in honor of HeathKit and the Cake Pan 5.  What do you think, John
     Dolan?

     1st.)  I saw a company advertising from Canada in March 1998 73
     magazine that sold a DDS VFO for $149 +Shipping covering 10Hz to 40Mhz
     factory adjusted 200mV peak to Peak into 50 ohms. Pure Sine Wave.
     spurious emissions down 40db.

2nd.)   www.radioadv.com   has a $79 product called Cycle Master that is a
frequency counter that can control a Voltage Variable VFO.  A varactor
controlled oscillator.  You build the VFO and wire in this microcontroller
device that adds RIT and dual VFO's (A&B), displays the Frequency on RED LEDS
and has input buttons to control operation.   This device draws about 800
milliWatts of power.  Go look at the information.
You could design your own VFO here.   Far circuits has a VVFO PCB offered that
follows a W1FB design from 1990 QST?

3rd.)  This is just a inexpensive LCD frequency counter for $35
        http://www.fix.net/~jparker/blusky/ccd.htm
This LCD frequency counter microcontroller design has potential to do more,
similiar to the www.radioadv.com Cycle Master C7 design but using less power.
The original designer would have to be involved to make changes to support a
VFO.

I built this Blue Sky Technology kit myself and recommend it to anyone who needs
a simple 100hz-32Mhz frequency counter around the ham shack.  Or wants to add a
Digital Display to their Radio.

Is the Heathkit name being used by anyone today?  One of the requirements
of trademark rights is that you must be using it.  One of the classic
cases in this area of marketing and law was IPANA toothpaste.  They just
stopped making it.  After a few years and as a test, someone contracted
for a few truckloads of generic toothpaste labeled with Ipana, and it
sold like hot cakes at an attractive markup over generic toothpaste, and
it was legal.

I'm thinking about a SB xxx product.  An add-on product for those
thousands of SB out there that folks still like, but drift like crazy.
Anyone got any recommendations for the design of such a product... a
variable crystal oscillator, or a frequency synthesizer (are there ASIGs
cheap enough yet to do this)
