I am working on the Receiver chapter for the LF book. I have a good introduction written by John 4GVC (with a description of the TS850, which caused many of us, including myself, to go this route) bu
For what it is worth : I use a Kenwood TS440 on LF, sensitivity is OK and if the internal 20dB attenuator is used the IM behaviour is very good (using my 'big' antenna for reception). 73, Rik ON7YD A
I use a Racal RA1792. Gradually becoming available on the surplus market now, at prices coming down from 'silly'. They started at £1000 a few years ago but are now appearing at £400- £500 and ought t
Hi Peter, Several of us are using the AOR7030 and are very pleased with it. Others that I know of are Vaino Lehtoranta OH2LX and Alan Melia G3NYK. Unfortunately I have no other rx to compare it with
Hello Peter, I'm using a Harris RF590 for LF reception, followed by a Timewave DSP-599zx. The Harris tunes from 10KHz up to 30MHz and is available on the surplus market. It was in widespread use in m

Marco et al .. I feel cheated - everyone else seems to have 1 Hz steps :-( By IF passband tuning, do you mean the use of the 1kHz and 300 Hz filters on SSB ? For a time before getting an IC746 transc

Marco et al .. I feel cheated - everyone else seems to have 1 Hz steps :-( Well, it is a software problem, the synthesizer IS CAPABLE of 1 Hz steps, but the software limits to 10 Hz. I can't explain
What happens when you press the 'Fine' button on the numeric keypad ? Doesn't the tuning step go down to 1 Hz ? Time to dig out again the manual... I think the tuning step is 1Hz all the time. All t
I think the tuning step is 1Hz all the time. All the FINE control does is change the tuning rate of the tuning knob to the display. The display shows 10Hz resolution whatever you do - unless there i
Alberto di Bene wrote I made a simple test. Using the Up-Down pushbuttons on the mike, the step for each pression is 10 Hz or 1 Hz depending on the 'Fine' setting. The display has the resolution fixe
Andy, But isn't the accuracy and stability of a cheap colour subcarrier xtal, pulled more than 100ppm from its normal operating point, going to swamp the values you derive from the 'nice' numbers gen
