Rob, got my first license in the 60s while at Collins Radio. Was learning then and still learning. Gotta love the reflectors and the net. Google may be our friend for searching the web, but the refle
Bill, I have experienced several such cases of fellow hams blowing crud all over a band, and "not hearing" those who report the problem. But most of the offenders I have heard are operating factory-m

The TS850S (and probably other transceivers) had an internal pot that could be adjusted to set the maximum output. In the service manual, it said to set this for 100w output with the drive set in suc
I remember that with the Drake C-Line, some ops would short the T4XC ALC line, which would increase the power output to 175W. Most vacuum tube transmitters I am familiar with did not have a power adj
Jim, USING ALC to control drive level for a power amplifier is a CAUSE of splatter and clicks. ALC should NEVER be used to set drive level. How do you do it, then? I would say that when transmitting

Jim, You are confusing speech processing, which is generally done at base band (that is, on the audio signal before it is applied as modulation), with ALC, which is control feedback between an RF amp
Well, to be fair, we don't have any choice given the options available from the manufacturers. (I'm ignoring homebrew for purposes of discussion.) I have seen many, many online posts asking for an al
The Elecraft K3, K3S, and KX3 are excellent performers on 6M, although the K3 needs a preamp for 12, 10, and 6M. They sold an outboard unit for the K3, but it's built into the K3S and KX3. The major
The reason they don't exist is that an all mode VHF/UHF only rig is not cost effective. It costs very little to add HF when the lowest frequency is already 50 MHz. The demand for a 50 - 2000 MHz only
Speaking of this, does anyone know what happened to that little piece of the 1.25 M band we lost a while ago 9220-222 MHz)? I heard that it had been given to UPS, who subsequently just let it lie fal
I have an early K3 and dont see any need for a pre-amp for it on any of those bands. I just checked the sensitivity with my service monitor to verify that. 73 from Fern VE7GZ The Elecraft K3, K3S, an
UPS still has dibs on it but doesn't use it. Makes me mad as hell. Somebody ought to petition the FCC to get it back, ahem, maybe "the national amateur radio organization"? On 1/4/2017 2:11 PM, Shon
The spectrum has been auctioned off to land mobile users over the years, primarily government. Technology advances rendered the intended use for UPS obsolete before it was even born. They elected to
Hi Fern, The best real world test is that the noise level should rise by 8-10 dB when you connect an antenna to the radio. If it doesn't, your ability to receive weak signals is limited by internal n
Cathy, Jim, and all, I have seen many, many online posts asking for an all-mode VHF/UHF rig that doesn't include HF. These used to be available, but have disappeared. Such rigs appeared on the market
