Hi Clark - I was not aware you had a YT channel nor was I aware of a hole on the side for cleaning the TR relay. I assume since mine is the Rockwell Collins from 1978 it will have that port. Good to know about that. You have beautiful equipment. I am considering that digital readout for mine but have not gotten it yet. I am definitely a D-104 fan also but have had to change all my elements out to electret type mics and add the 9V battery in the bottom of the mic. I will have to ask you about some of this next QSO. 73 WA4QGA

Hi Clark,

I'm just in the process of getting a KWM2A. I've been licensed for over 20 years and passed my ticket back in 1983. I couldn't afford a radio when I passed my full license and found the joys of beer and the fairer sex as an adolescent :) I got licensed when I heard a Radio 4 (UK) programme about the work that our brethren did to establish comms on that awful day, so my interest is reliable comms.

I have never used a tube PA transceiver. I have the Collins manual but it seems to only cover bringing up the radio at full power. I don't want to damage it so are there any tips you may be able to give me to bring it up gently to 20W into a 50R resonant antenna rather than making a complete mess of the radio's PA?

Thanks for the tips on the relay cleaning hole and the Teflon wiring covering. I know very little about the radio. Is there anything else you would suggest I look for prior to purchase? I've been offered the radio of £500 and it looks in mint condition?

Hello, great station. I am searching on the internet for the regulator mod for the power supply but cannot get much info. Do you have any link that can help? Thank you.

That is a magnificent old Colins station set up. Did you sell it?

you have to sell it to someone who is queer for these rigs to get your money for it. like it but its not worth big money to me. a new sdr rig will blow this away and you can get a ft-710 for 900 bucks and run circles around the old collins all day long. I have a 30s-1 and love it. paid 900 for it and just picked up a spare 4cx1000a tube for 50 bucks works great! amplifiers are crazy money now that's why i went with the 30s-1 good bank for the buck. hope you get your asking price.
