Re: Topband: Relay bounce

Thanks for all the suggestions. Let me give you a few more details. I recently complicated matters, which seems to have exacerbated the problem. Instead of using the rotary switch on the RCS-4, I am now controlling over WiFi with an ESP8266 driving relays, which then apply the correct voltage on

Re: Topband: Relay bounce

While I totally agree with the comments on the poor performance and life of the contacts on open frame relays, my experience with noise from relay switching has been that it is usually a failed snubber capacitor or diode across the relay coil. Occasionally, especially with rotary switches, the

Re: Topband: Relay bounce

Steve, Older RCS-4 used open-face relays which are more of a problem for relay bounce. Newer RCS-4 use sealed small-signal relays. Getting one of the newer units may solve your problem. 73/Jon Jon P. Zaimes, AA1K Tower climber for hire http://www.aa1k.us/ Cell: 302-632-2353email:

Gene, My inverted L is at teh edge of my lawn. I have 35 radials in a 200 degress radius in the wooded arear of my yard. I add 6 more radials in the grassy area of my yard in November when finished with the mowing and remove them in the spring. I measure the impedance before and after. The

I know how big a staple gun is for 1/4" staples. Is one for 6" staples 24x larger?  That would be big.  Is it pneumatic? Mark On 2/22/2022 4:09 PM, Ken Claerbout wrote: Areas of my yard have a lot of stone. Six inch staples were a pain to use. Four inch worked better, in case you have

Re: Topband: Lawn staples

Areas of my yard have a lot of stone. Six inch staples were a pain to use. Four inch worked better, in case you have similar soil. Also, if you are going to install a bunch of them, do yourself a favor and buy the staple driver tool which makes it a breeze. 73 Ken K4ZW On Tue, Feb 22, 2022 at

Re: Topband: Relay bounce

Small signal, dry contact relays are made from different contact materials than power relays made for higher voltages and currents. Any fix that cleans them or removes the surface oxide that inhibits low voltage signal transmission will likely be temporary. Plus the high power relays are

Re: Topband: Lawn staples

I think I gave $18 for a box of 1000 at a hamfest in Joplin MO a couple years ago. Honestly, I can't believe how cool turf staples are, or that I didn't use them for all the years before that. They really are the easy button on putting down radials on the ground.  I use a mower to get the

Re: Topband: Relay bounce

Steve, Does the switch produce an S9 spike on any transition of the switch (i.e. from position N to position N+/-1) or only on a certain subset of switch transitions? That might provide a clue as to whether there is a problem with one of the relays or the power supply that energizes them. I

Topband: Lawn staples

I retired a couple of years ago and no longer have to launder my white dress shirts.  Therefore, I no longer have a ready supply of wire shirt hangers collecting in my closet.  Therefore, I needed to buy some REAL lawn staples to add more radials to my shunt-fed tower's ground screen.  FYI -

Steve, Using open frame relays can often lead to problems, especially in an outdoor environment in a low signal RX path. I have well over 40 relays at my remote switching various RX antennas in the field. Over the last 10 years I have had no failures or intermittent issues using sealed small

Topband: Relay bounce

I am using an Ameritron RCS-4 antenna switch to select between beverage antennas. Recently, it has developed a bad case of relay bounce causing an S9 spike every time I switch between antennas. Any suggestions on how to improve this ? Since it's only used for RX antenna selection, I'm amenable to
