Remember to ground the Polyphaser!

Looks nice. I do not have an end fed wire at home but use them all the time portable.

It tunes 80 through 6 meters with a LDG AT-200Pro II automatic antenna
tuner, will tune 160 meters with manual tuner. Still experimenting
with counterpoise length. Simplest and cheapest way to get multiple
bands on a limited space that I have found, also easy to install for
portable or emergency use.

I want to do one of these in the future.   Thanks for the post and motivation charge.

Curt
 

I thank SKCC ops putting up with my foolishness, last QSO was with WI5H, Mike, in San Angelo.  The little radio seems to reach out 100-300 miles, my contacts ranged from 3 miles to nearly 700 miles, TX, AR, LA, OK, GA.  Pushing nearly 800 mw into an 80M dipole up 50 feet.  Using 10 VDC supply.

Being limited to a single frequency, tied to a straight key, and not being a night owl, this was nearly as hard as making WAS for me!

Re: KN-q7a

Paul Ross <deadgoose@...>
 

There are some files with mods. One suggested replacing the gain pot with one with a switch. That would have involved running wires from the back panel area, and I was reluctant to do that, as I didn't want to risk picking up RF on the power supply leads. The SPST switch was an easy fix. Early versions of the PC board did not directly support a speaker microphone. Mine does. I got my kit from the guy out west, as I figured if I had problems, support would be better than attempting to work with Adam in China. I believe there is a new version of the rig out. DDS tuning, I think. If you are into small voice rigs, look up the DSB rig from Ozqrp.com. VERY interesting.

Yes very good idea having a larger tuning knob and an on/off power switch is a great idea .I hate having to disconnect the battery leads or pull out the power connector each time I am finished. Not sure why they didn't Include that in the kit manual.
Will email you some time in the future.  Many thanks!

I built one a couple of years ago. Due to inexperience, had to get some help on installing the small SMT driver transistor. Otherwise fine. I did put a SPST switch for power on back panel. Tuning is a bit touchy, so will likely put a 10 turn pot in for tuning. Some drift, but it settles down in a bit.

Re: KN-q7a

Terrible propagation on 40m ?  Last night managed several 6600 km reports on WSPR running 150 milliwatts to my vertical -- all directions.  true - close-in propagation can be rather directional - but at times even short distances can be strong at night.  Best to radiate signals and see where they go.  also keep in mind it is summer - higher QRN and a bit more absorption.  we still have ions to use.

Hi! Yes, I have built the KN-Q7A rig. The dds vfo came as an extra and I installed that as well. To be quite honest, it is a ho-hum kind of rig. It worked, but there are a swag of better rigs out there. Would I build another? Nope, I'd save my money!

Hi John,


I'm just getting ready to start assembling a CS-40 (40 meter band), which is basically the same as your KN-Q7A but with a digital VFO added.  There's a Yahoo group covering the KN-Q7A and CS-Series SSB transceivers here:
