You made my day Dave! Raj

RV1 is normally at half position. Some boards will need higher or lower settings depending on the power needed. Raj

Tom, Gently move the interstage transformer toroids and you may find a jump in power. I have see some test boards with me that had shorts near the soldered ends. Separating the leads solved the proble

807 was QRP! I am an 811 fan.

The gate does not draw any current in mosfets. Raj

Exactly what I found on some boards. One had a mixer diode leg open and was partly deaf. "Honey I shrunk the sensitivity or Honey I killed the RX" Raj

Compile it with an older IDE version. I remember someone mention here that the new version may have more bloat in the compiled code. Raj

#ubitx #nano #v6 #ubitxv6

Rajesh, Always mention which version of Bitx/uBitx you are asking about! Raj, vu2zap

Write to sales at hfsignals.com or sales at hfsignals dot com remove spaces and and replace the AT and DOT groups io does not show the email ID. Raj

#v6

My boards have worked continuously on 15V with no issues. The power output increases, you only need to put a heat sink on Raduino 5V regulator as it gets uncomfortably hot. It may then drop voltage. I

#power #v5

How have you concluded that it is defective?

Bob, I was told that the Toyota Camry handles charge between 20-80% only and they warranty the cells for the life of the car I think. Raj

Some library routines must have become bloated with new "features". In the old days I wrote library routines in MASM just to shrink code in DOS! Raj

Try reducing power by a watt or two and see. If the harmonics drop significantly then I'd say the PA is being over driven a bit. The power you are getting at the low bands is less than I would expect

You could try replacing relays KT1/2/3 with Axicom RF relays, that should reduce this. Check earlier posts for details. Raj

For proper SWR readings your dipole must have a 1:1 Balun at the feed point. The resonant length you have calculated is for plain metal (copper) wire. Wire coated with plastic will not have the calcul

It helps if you leave commented part of post that you are referring to. I think you are referring to QST, all magazines I have subscription to are only available in PDF and not print currently. Raj

They can't! It interferes with blue bias pots. They used to shift the pot forcibly to accommodate the heat sink. The pots got disconnected and caused havoc. So Lifting the higher is a good solution! R

I've seen this and its always the capacitor! Raj

Sumit, One of your filter relays or associated components in the filter may have failed. Higher power means higher voltage across capacitors etc. Raj
