Yes, that is what the update info said. It would be nice to be able to store filter and AGC settings in memories... maybe a future update.

A lot of thunderstorms and lightning in northern Maryland tonight. Listened to the CR-1 for about an hour with an external 25 ft long wire. I find the response to lightning static to be much better than before. You take the hit, but almost immediately are back to normal listening. To my ear it sounds as if there might be a bit of noise blanker action taking place in addition to the better AGC performance. Difficult to put my finger on it, but I do like it better than any of the other software configurations. Does anybody else notice what I'm talking about with regard to a sort-of noise blanker effect during heavy static? I was using good headphones, mostly.
Yes, it's like the lightening completely saturates the input so instead of a loud pop, the sound is quickly muted.
The latest firmware does not make tuning in VHF acceptable. Turning the dial still makes cracking noises that drives the AGC into deafness. Oddly it's less of a problem above 125 MHz which makes me feel like it might be a hardware limitation.

Hmm, mine doesn't do anything like that in the FM BCB, the AM aviation band or above. Maybe you should contact CommRadio to have your CR-1 checked out.
Again? I already had the thing sent in for the defective TCXO.

Well, whatever the issue is, I hope you get it resolved. What antenna are you using? I am using just a whip for vhf and above.
Same here, one of those BNC whip antennas.
I hate to bug Don a third time but if people say my radio shouldn't be doing this, I guess I'll have to.

Well, it's a pain for you to have to deal with these things, but I suspect they want you to be a happy camper.
scowl,
I hear some clicking while tuning the aviation band only but no deafness from the AGC. actually vhf tunes a lot better then before. I run the AGC speed on fast setting. I run a 25ft wire thru a MJF16010 random wire tuner it helps on the 80/40m ham bands

scowl, all-
Just to confirm, I'm running DSP 1892, PIC 1883, unit S/N: 0005.
The one consistent nag I frequently gave Don was the noticeable (what I'll call) "tuning transient", the slight popping or clicking noise that accompanied each step of the tuning knob as you turned it. I heard this pretty much everywhere. The correction of that, to make the receiver sound pretty much the same as tuning an analog rig (except for the fact that you are going in discrete 10Hz minimum step size), was for me, the biggest improvement in this latest software revision. To remove the tuning transient required significant reworking of the AGC and a few other areas. The three speed AGC was incorporated as part of this change.
I just tried the same experiment described, Diamond RH77 BNC whip antenna, CR-1 per earlier description. I did not hear any tuning transients on any mode, in 80 MHZ range, on Broadcast FM band, in VHF aviation band, business VHF band, no place. scowl, please verify your software revisions. In the betas prior to the field release, and in this field release, I truly do not hear any tuning transients - and I am quite sensitive to that topic. It's definitely one of my hot buttons!

You mean what firmware did I load a few days ago?

I just ask, because I've gotten myself mixed up from time to time... and the results weren't pretty!Tested mine on vhf and it has none of the issues you describe. Tuning chuffs just a bit ,but it is not desensing or causing any issues. Mine is s/n 105 and I also sent mine back for the TCXO fix. I am very happy with the new firmware package, you should really let Don know about the issues you are having. It will only help to keep positive development continuing for this investment. Maybe if you send it back to get fixed they will send it back in the fancy new packaging as well!! dion
I don't plan to be spending any more of my time helping them with their product.
One hardware defect is acceptable. Two isn't.

Understood! I am a field service tech, and it is my job to show up at my customers location and "make it right", so I can see your frustration, but the wisdom of knowing that your unit is still not up to snuff in comparison to others, puts the ball in your court to have your issue put on the hot list. No sense having the radio you paid alot for sitting around as a paper weight, and if it is not a paper weight to you,(do you use it despite the issues you have on vhf) then it is worth resolving. D
The CR-1 is marketed as a great HF receiver with some VHF and UHF capabilities. That is exactly the receiver that I own. There's nothing in the manual that says I should compare the performance of my radio with others to see if I got a good one.
sorry. You posted the issue,We are all just trying to help. I have learned alot from this forum and look forward to all observations.D
