Thanks Will, been on today working a few special event stations. The radio is doing great so all my patience and efforts were rewarded.
This case is closed and came out well. AC 5 up described these processor radios well about something perhaps getting out of tune the more bells and whistles.

This is a tangent off my other thread here about Jpoles.

Here I use an ordinary TV balun to convert the 50 ohm coax to a balanced feed to the Jpole antenna.  This avoids feedline radiation.  And is smaller than ferrite beads and coax coils.  The only unusual item needed is a BNC to F adapter.   These baluns can handle several watts.

I bought a FT-60 a year ago, and it suits my needs. It actually has a squelch knob. .... Look at the HRO site, Kenwood has a 5 watt tri band, Yaesu has a good selection, Icom seems to be into digital. .... I do like to look at the pricey models, but at this stage it's prudent to spend on full size rigs.

I use the stock mic on the 6500 , I have the eq set up and don't overdrive the mic. I don't use the processor. The compression is more for odd band conditions.
I have very little experience with ssb communications but trying to work all of the colonies stations , I was forced into some ssb contacts., I used the flex and was
able to break any pile I entered. My experience is to use the 45 watt setting and I get about 60 watts out on ssb. More than enough. My rig is not sensitive to rfi.
I have 3 other hf rigs in the shack and never experience anything one any of them, flex , kenwood , apache labs or elecraft. lots of grounding straps.

I would start by moving the mic to about 70%-80% of full scale. over driving the audio is not good on any rig. check your ground connections.

Happy 4th of July !!!  I have a 35' steel mast holding the centers of my 2 inverted vees. If I insulated the base mounting brackets on the deck and run a beefy variable cap in series with a coax line will it load up fine on 40? With radials of course. The mast is currently grounded to an 8' ground rod with #6 wire about 4" away. What would be the best arrangement to switch between having the mast grounded except when I wanted to use it on forty as a vertical?  physically unhooking the ground connection? A switch or relay? Seems to me I want to keep as heavy duty a connection as possible for the ground. Do any of you do something similar and what is your method? 73 Gary

Have just moved to a new location and started setting
up the station. During setup the line voltage was measured
and found to be 245 volts (single phase).  Fired up the Henry
3K-A and checked the HV voltages. They are running high.
The CW mode HV is 3500 volts nominal and the SSB HV
is 4100 volts measured with a bench meter and HV probe.
This correlates closely with the indicated panel meter
readings. The idle current in CW is approximately 100 mA
and 210 mA in SSB mode which falls within specification.

This is of concern as the rating on the power supply
capacitors is 4 uF at 3500 volts. The manual indicates
the voltage from the supply should be between
3300 and 3600 volts in SSB mode. The voltages specified
are based on a line voltage of 230 volts.

Anyone know of an easy method to reduce the line
voltage to the specified 230 volts so the caps are
not pushed over the limits? Am I being nervous Nelly?

I use an inverted L, 88 ft, trapped at 67 ft for proper 40 M operation, so traps make me happy as well!

The base of the injverted L has another parallel LC that brings the SWR down on both 160 and 80 to keep the fairly long coax loss down to below 1 dB.  The base LC affects the trapped 40 M section very little.

I use a tuner as well for full band coverage, and total loss on all bands, full 160, 80, and 40 M, is less than 1.5 dB.

I finally come across some printed help that explains what I did not understand.

Yaesu VX8DR has a lot of bells and whistles and is supposed to be IPX7 resistant to dust and moisture. I'd love to have one too. Cheesy
