500kHz, for a $130 sounds pretty good. I guess to divide that by 5 should not be a problem but it might add a some bucks to the cost and increase the complexity. At a $130 as is, it sounds pretty good.
I'm curious to see how it turns out.

Ah didn't the FS4 use 500Khz steps? It was for the band XTL replacement. 500Hz would be kind of over kill for such an instrument IMHO. OTOH maybe you meant to say 100KHz which would make sense for use with the TX which requires "odd" XTLs for areas of the HF band.

"Lee Bahr" <[EMAIL PROTECTED]> made an utterence to the drakelist gang ---------------------------------------------------------------------- One more thing! What kind of readout is on this thing? LED display?, LCD display? No display? How do you tell what frequency you are on? Using a push button for changing frequency would require some kind of readout. If rotary detent switches were used you could at least look at the numbers on a knob. Not possible with push buttons as you describe. Or, is the readout part of the "etc" provided by the purchaser? Maybe you have a voice annunciator in mind! Me thinks I shall wait for more info and unit testing before I would take this project seriously
In all seriousness, you really have to do better then this to get any real serious feedback. As described, this project is a Pig in a Poke!. I've been having fun with this. It's OK to say you are going to design something and give no real info but to ask a group for the amount of serious interest based on this given description with glaring and obvious flaws and/or mistakes is a waste of everyone's time and energy.. (Your's included). There has been no science or logic in the description. I hope you really meant to say 500hz steps rather then 500 khz steps as you say in your corrected message. 500 hz is truly not even enough resolution.. 100 hz is really what is needed. Also the readout methode is a VERY IMPORTANT part of all this .Give some good data and you will get some good answers and real help from knowledgeable people.. Right now, you say the unit has "push button" switching and doesn't use rotory switches. Thus you would need a readout of some kind or annunciator or the unit would be useless. With many hams and non hams today not knowing morse code, the annunciator would have to be in voice rather then in cw. With readout I don't see how you could do it on $130. You could do it with rotary switches for that amount of money. I have a feeling none of the above has been thought through in its design.. Lee, w0vt .

"Dan Cotsirilos" <[EMAIL PROTECTED]> made an utterence to theitem---------------------------------------------------------------------- First of all "hosing" was a typo I meant "housing". 12 volts would also be needed also. Second 3 LED's was a brief description of the device. Thewill be clean. It is being designed by a ex-Collins RF engineer who can build communications receivers from scratch so all worries of poor design are not necessary.
