It doesn't say how to get that little stop screw out of the band switch. I can see it. But don't see any way to access it short of removing the band switch.?Sent from my T-Mobile 5G Device

do you have a l4b or ?L-7 power supply ??

Tim,I’m interested in your AC-4s. I sent you an email through QTH. ?BarryKJ5GQM

I just added a capacitor to mine, that’s all it took. My SWR is 1.1 to 1.3 across entire 10m band with solid 1kw out and 60w exciter. Note: I did not add a capacitor to the 15m pi network as it

The way to check narrow filters and the IF alignment is to zero beat a signal and set the PASSBAND knob to 12 o’clock. Maximum signal strength should occur with the pointer at 12 o’clock. If this

Group- I've installed the set of three Noble CW filters in my R4C, and I like them. I have noticed that if the 500 or 250 CW filter is selected, the passband center is no longer at zero (12 o'clock) -

Today most of 6m activity is digital. Not much SSB and even less CW. Rob, NC0B

Thanks Jim. I was wondering if someone out there had made there own input tuning coil for 10m instead of just adding a capacitor.?Sent from my T-Mobile 5G Device

My TR6 has a CW filter installed. ....Dave

Jim the 24 VDC is okay and I changed C2108 last spring as it failed. 73, Jim VE1RB [email protected]> wrote:

I got the last LSB filter direct from Bill Frost when Drake had their clearance sale of all the Ham parts. Just because I could. I probably got a CW filter at the same time if it was available but I

My TR-6 only has the stock USB and an AM filter. I’ve never thought I’ve needed a CW or LSB filter but they are rare. Steve Wedge, W1ES Time flies like an arrow. Fruit flies like a banana. Sent

How about "I'm not sure"? :D It's been so long that I don't remember. "Lyndon VE7TFX via groups.io" <lyndon@...> wrote: -- 73 -Jim NU0C

Also check the +24V from the PS board. C2108 can cause strange PLL issues as it fails, and it WILL fail eventually. This is a known failure point in the TR7. "Jim Harris via groups.io"

Bob & Group, I think I've got it solved. Using an IFR1200S (GPS ref) service monitor, I tuned the R4C and T4XC oscillators to 5645, as well as the AM oscillator. My R4C (recently back from service)
