PTT disabled - I just checked pin 7/9 to ground and it appears pin 7 is shorted to pin 8. I'll remove and reinstall U10. Maybe too much solder paste under the...
Robby's documentation clearly calls for 2.5 volts on pins 7 and 9. Having the luxury of a scope, I have never done DC testing in this area but it would appear...

I'm planing on doing the Altoids can too with BNC connectors. The only difference is I'm thinking about also adding a bypass switch. That way I won't have to...
I fixed the key clicks. I sent audio from Rocky to a virtual audio cable and from there to my sound card and it sounds pretty good now. Apparently, Rocky...
With very few exceptions (notably, Apple hardware), notebook computer audio is wretched. It has a high noise floor, is full of birdies, and generally has much...

I am trying to understand the purpose of this Delta 44 interface module. I don't see the how it interfaces in the overall block diagram. See this link for...
It plugs directly into the delta44 and removes the need for a breakout box and 1/4" plugs. You can plug 3.5mm cables directly into the module and into the rxtx...
The Delta 44 comes with a break-out box that plugs into the card in your computer and has 1/4 inch jacks to connect to the 4 channels in and out. You would...
Hi Paul, It is not compatible with the ap192. I have both cards and the breakout box for the delta44 is 15 pin and the ap192 is 25 pin. It is completely...
Hi Mike, I just want to correct you about the number of pins on the delta44 breakout box. It is a DB15 pin, not a DB25 pin. We don't want to confuse Mike on...
Jasmine I am going to argue with you a bit on this. Everything you say is true in the world of high quality recording audio. And, of course, a computer with...

The filters are documented in Robby's page at http://www.wb5rvz.org/ Remember, you do not need a filter for every band. The external filter is only required...
Thank you in advance for your time! I determined the final number of windings for each coil with an LCR meter. I figured I was shooting for a certain value of...
I'm trying to figure out now that I've finished the build why the rcvr is no longer working., I Discovered that when I check continuity on the 2 primary pairs...
I seem to be having a problem interfacing FLDIGI with HDSDR using VAC. I first noticed this when I was adjusting output power for my Ensemble RX/TX for PSK31....
After all attempts at using VAC with HDSDR and Windows 7 32-bit on a netbook, the PSK reception was only about 75% correct at best. My PSK software is Digital...
Thanks Jim for the response and info. I thought about trying out the hardware avenue, but I was hoping for a cleaner approach. I'll probably try the hardware...
