Re: Anyone have an R4B dial?
It may have been. The owner had such great expectations when he sent the rig and all the new parts to me but he bought them so I don¡¯t have any receipts. 73, Steve Wedge, W1ES Time flies like an

Re: 6HS6 Price and Availability
Michael; I can't explain the high price of 6HS6's....maybe just basic economics - supply & demand? But I can confirm that a 6AH6 used in place of the 6HS6 works just fine, at least in some spots in

OK sorry for the mistake I used the term in reference to the meter not reading correctly. 73 TimWB8UHZ

6HS6 Price and Availability
Okay, so I know there has been a lot of discussion about the cost of these tubes. ?They are a relatively high transconductance IF amplifier tube ¡ª so what? ?I priced these tubes today from roughly

Re: Anyone have an R4B dial?
Steve, Are the dials you have seen made by Radio Daze, perhaps? 73, Michael Smith, N4KZO

Re: L7 question
OK but please stop calling them shunts. They are series voltage dropping resistors. The only shunt is the pot. A shunt is a resistance across the meter terminals to increase the current value needed

Re: L7 question
Jim thanks for your help regarding the location and the voltage requirements of the shunts. These are the the resistors I purchased from Mouser, with the data sheet available to open from Mouser below

Re: L7 question
Yes, that is where they are. It is a simple circuit. The only shunt in the circuit is the 10K pot R17. It adjusts the amount of current to the meter to provide a calibrated reading on the meter. The

Re: L7 question
Your L7 S/N is close to mine, I would perform the grid current meter calibration step to verify the meter functionality which is supplied by a voltage divider network (1 ohm 12w resistor) into a 200ua

Re: AFG/RFG controls R4C (W1ES)
I just jumpered the RFG and used an on/off/volume pot on my TR-3.? I never use the RFG on any radios I own.

Re: L7 question
Thanks Thomas its not the switches for the meter and other aspects of the meter forward watts reflected watts etc, it all works, lights are on etc. Pushing the Ep volts meter several times changes

I recommend cranking the dial back just a tad on the toaster. Barry - N4BUQ

Re: Using the PLJ-6LED digital display with the R4C
The PTO needs very good buffering. Otherwise the signal drops and sensitivity is reduced significantly. I used an FET as a source follower with 50 ohms. So you can connect standard coax. Of course to

Re: Using the PLJ-6LED digital display with the R4C
If you don¡¯t really need to see the MHz, you could tap the PTO signal, it is larger and is the same for all bands. 73, Gary WB6OGD

Re: Mn2000 broken insulator
Actually I made a mistake. Mine are 3/8 by 1 and 1/8. Are your about 1 and 1/8 Long ? That would be great. ________________________________ Sent: Tuesday, January 7, 2025 12:30:13 PM To:

Another source for Mn2000 broken insulator
If one wanted to switch to phenolic spacers like those used in some MN-2700 tuners, eBay has quite a selection. ?Might even have the ideal size, if not, they are easily cut to length with a hacksaw.
