Thanks for the link, they look like what I'm looking for and the price is right. Eric, KE6US also gave me a part number with Mouser for a similar part, a single coil model.

I have no idea what Bruce used, but I've used the Omron G6HU-2 series DPDT latching relay for several RF projects. It is used in the KAT1 ATU for the K1. Mouser P/N is 653-G6HU-2-DC5 or -DC12

Hi, Cecil. Thanks for the message. The latching relays I used are NAIS TQ2-L2-5V. If you look closely at the picture I posted in the files section, you can actually read the part number. These are in

I sure want to express my thanks to Bill Tracey, Phil Covington and Alex for making the SoftRock project what it has become. The hardware represents a very small part of what is good about this

Where did you get the latching relays, and what are their numbers. I have several projects that could use latching relays. Hopefully they are affordable, the ones I have found are very pricey ( > $10)

Hi, Alex. Thanks for your comments. Since the next generation of SoftRock currently in development will require the physical swapping of band modules, having per-band profiles in Rocky would really be

Hi Bruce, Great work! It should not be too difficult to add per-band profiles to Rocky. The next logical step is to switch bands electronically from the PC, e.g. with this single-chip USB-to-parallel

Hi Bruce, The I and Q signal integrating caps on the QSD output should be decreased as well as the feedback caps on the two audio amplifiers. I am going to 0.027uF on the signal integrating caps and

No mods needed for 96K sampling, plug and play as they say. 73 - Mike WA8BXN

Tony- Will any mods to the audio portion of the SoftRock need to be done to allow 96 Khz sampling? I don't currently have a card that supports this rate, so I can't try it myself. -Bruce N1RX

I just added a second photo to the files area with labels. This should help see what's going on inside the multiband SR. 73, Bruce N1RX

Bruce, Very, very cool! Maybe with v5.0 you can make it a five band SoftRock and with a soundcard that can sample at 96kHz the band coverage on each band will be 96kHz. This project continues to be a

Good Morning All, The parts for the v5.0 prototype build are on the truck for local delivery this morning with the PCBs due in October 27. Also I was able to order the 16 missing OPA2228UA opamps from

I plopped my Multi-band SoftRock onto the scanner bed and obtained a reasonable quality picture. I have posted it in the Files section rather than Photos to allow a larger, higher-res version. As you

Hi, gang. As I previosuly reported, I have been working on a multiband SoftRock. I finished it up last night, and I am happy to report it works great. I used a version 4.0 SoftRock board from AmQRP. I

OPA2228UA ICs are in stock at Arrow Electronics http://www.arrow.com/<http://www.arrow.com/>. At $3.14 per chip the cost is not trivial. GE and 73, Jim WA2UMP

Yes, very good point, and I agree with it. It's always a milestone for me when I join a new group and suddenly someone posts a question that I can answer! hi. Eric KE6US www.ke6us.com --- Phil

Thanks Tony, paypal sent. And thanks for all your hard work on this project.
