Jerry, Thank you for the feedback. It is a good summary of the data that has been presented in this forum as far as I know. No one has yet published any data on either the susceptibility to high RF

Correction: ...a 3/4-in square heat radiator attached to the regulator....

Don't recall if my V6 had one but I remember seeing a picture of the regulator and it had a about a 3/4-in square heat regulator attached to the regulator. If one is in your parts drawer, I think it

I think Iz is right, that DC path does help with static on the antenna, which can get quite substantial with nothing more than the wind whistling past. Evan is also right, the DC path does not

iz, The dc path does not really help in protecting the rig in my opinion. Q90 is the first driver stage in the transmitter, it is connected before the receiver low pass filter, and has been known to

If you continue to have issues Jack feel free to reach out to me or David (N8DAH), Here or at info @ kit-projects and we can help fix and make things right if need be! Almost a thousand happy

Update - I tracked down the problem. I had soldered the ground of the BCI filter to what I thought was ground, it was not... Now I have noise consistently within the band on the BFO alignment tool.

I am not totally sure, but that DC Path at the antenna input might provider some degree of protection in case of statics.

Thanks Curt.

Bill great you are checking these things as you assemble. do examine the schematic and you will see what Jerry is citing - funny thing I was once worried as you! oh yes - when you power up and touch

Antenna connector looks shorted to ground because there is a DC path through K3-13,11, K1-12,14, L1,L2,L3,L4, T2-1,6 Jerry, KE7ER

I am just completing my V5.  No power applied yet.   Everything is remove from the board and it lays naked in front of me.  The following connectors are installed; Power, Raduino, Audio, as well

The bare board should be available on www.amateurradiokits.in in a few days. A kit with most of the components will be available later. 50V is too high - 28V is the absolute max. It requires at

Hi Lori's, Thank you for your input. After posting this I did wonder about a potential ground loop. I have noticed that the radio is a lot less sensitive. A +10 station on my Yaesu was lost in the

Hi Jack 2E0GDV, the problem you filmed in the video would seem to derive from a strange ground loop that somehow affects the receiver, perhaps due to the two ciscuiti added in cascade or perhaps to

Can I buy somewhere this marvelous amp? Does it work in 50V PSU? Cheers, Rafael PU2UIT

Andy, Regarding the multi-band LPF board - I needed one that was PC-controllable because I mainly operate remotely (shack is upstairs, PC is in family room). So I designed my own board, which uses

Leonard - your manual was among the best guides that I found while researching and eventually building the amp. I think I've still got a browser tab opened to it on my shack computer. Kudos &

Hi everyone, I installed the AGC board from kit projects, following which I had some gain issues. I think that was my fault now, but I thought that maybe the BFO needed aligning. So I did that, but

Todd Exactly. The dual nomenclature indicates that you can use either one type or the other type of devices. The base-to-base line on associated schematic is just a shortcut to simplify drawings,
