Re: [Elecraft] Future of KPA500 & KAT500
Dave, Do you own either/both the KPA500 or KAT500 and are familiar with their operation? The KPA500 is not involved in the receive path, it is only used for transmitting, so it doesn't cause an issue on receive. When in standby the amp is bypassed and the T/R circuit feeds the input to the output. That output is connected to the KAT500 input. My antenna system, for various bands, is connected to the three outputs. Yes, if I just want to monitor a number of bands/frequencies I can press the KAT500 mode button repeatedly until the unit is in BYPass so that it won't attenuate receive signals. Unless the KAT500 is bypassed the last tuning solution will be applied regardless of band or frequency selected on the rig. Then, for each frequency I want to monitor, I can then press the ANT button on the KAT500 repeatedly until the correct antenna for the desired frequency is selected. Depending on the memory or VFO band/frequency selected it may be necessary to do this repeatedly. This will not work at all in the case of scanning. When done listening on various bands/frequencies and I want to return to transmitting I have to press the KAT500 mode button repeatedly until the unit is in MANual. Then press the ANT button on the KAT500 repeatedly until the correct antenna for the desired frequency is selected. All off this is doable but I'm looking for a more automatic system like that built-in to the Elecraft equipment. It appears that I need to design and build what I want. I've taken up more than enough forum time on this subject so it can be closed.

Re: [Elecraft] Future of KPA500 & KAT500
John, The radio, an IC-7610, and the fact that I use a HB band data cable to the KPA500, was included in my original post. The band data cable switches the bands on the amp, except for WARC, but there is no communication to the KAT500 so it remains on the last band/frequency and antenna selected at the last application of RF. The problem is that if I am just listening and select another band the KAT500 will not move to the correct band and antenna. This is not a problem if I intend to operate on the new band but it is particularly inconvenient when simply switching between radio memories to check for activity on stored frequencies which could be on any band/antenna. It also affects memory scanning for the same reason. After a band change the KAT500 is not on the correct band and antenna so the received signal is greatly attenuated. Elecraft transceivers "talk" to both the KPA500 and the KAT500 and keep them updated with frequency changes so the KAT500 selects the proper tuning and antenna for the frequency selected on the rig without transmitting. I'm looking for a solution that mimics Elececraft's operation. An Arduino project has been suggested to me and I might need to learn to program one to read Icom CI-V data and communicate with both the KPA500 and KAT500 if I can't find any other solution. Apparently I'm in a very small minority that would find this feature useful. As for using a Top Ten band decoder, or any other decoder, to switch the antenna system external to the KAT500 would not help with the KAT500 issues of remaining on the last RF-selected band and antenna. Simply changing the antenna external to the KAT500 does not help with the KAT500 still being tuned to the wrong band and antenna and attenuating the received signal. *Ken * *WA2LBI * *LG G6 * -- Original message-- *From: *j...@kk9a.com *Date: *Fri, Jun 19, 2020 09:55 *To: *elecraft@mailman.qth.net; *Cc: * *Subject:*Re: [Elecraft] Future of KPA500 & KAT500 The KAT500 only has three outputs which for me is insufficient and I do not even operate WARC bands.

Re: [Elecraft] Future of KPA500 & KAT500
The mod applies to the ability to increase the sensitivity (gain) of the amp by bypassing the input attenuator so that it can be driven to a useful power output with a lower power exciter. There isn't any suggestion that the amp should be driven beyond its normal power level. Hence unless the exciter was dirty, clean signals is not part of the equation.

Re: [Elecraft] Future of KPA500 & KAT500
I own a KPA500 and KAT500. Both work very well with my Icom IC-7610 but operation could be improved if they could communicate with the Icom CI-V bus. I do not own a KPA1500 but from my research I see it can communicate directly with the Icom CI-V bus to switch the amp AND the internal tuner/antenna selector when connected to an Icom rig without any RF being transmitted. The KPA500 and KAT500 have no such CI-V capability. The Icom band data connection on the amp works but does not address the WARC bands. There is no provision at all to communicate with the KAT500 so it must RF sense to switch bands and select the correct antenna. While this works well when transmitting it is of no value when you are just listening or scanning. The KAT500 will remain on the last band and antenna where RF was present. For example, my KAT500 has a 75M dipole on ANT 1 and a 40M-10M fan dipole on ANT 2. If I am listening on 75M and then switch bands to 20M the KPA500 will switch bands using the band data cable I built (but not on the WARC bands...) but the KAT500 remains on ANT 1 and tuned for the 75M frequency. Of course, this seriously attenuates the 20M signals. I would like to see a plug-in product that connects to the IC-7610 (or other Icom), the KPA500, and the KAT500 that reads the Icom CI-V bus commands and sets BOTH the KPA500 and KAT500 to the correct band without transmitting, and in the case of the KAT500, also selects the proper antenna for the frequency. Since the KAT500 antenna is assigned per band in the KAT500 programming I believe the KAT500 would only need to know the frequency then it would select the proper antenna from its internal memory. If such an Icom CI-V plug-in device already exists that addresses BOTH the KPA500 and KAT500 issues outlined above please direct me to the product(s).

Re: [Elecraft] Future of KPA500 & KAT500
Paula Keezer NX1P modified a KPA500 to allow it to be driven to about 500 watts by a KX3. She published it - but I can not find it on the web. The mod increased the gain by less than 3 db (seems I recall 2.something). You would need the 12 to 15 watts to drive it to about 500 watts. The modification involved removing the input pad and modifying the feed back loop to the microprocessor. I thought about doing the mod to be able to run a net with my KX3 if my K3 quit. I have a KXPA and decided not to do the modification. I can just remove my KX3 & KXPA from my truck if I ever need a backup to drive the KPA500. Probably 10 minutes work and find the bag of portable cables. BTW - Ms. Keezer's modification was very detailed and she had many cautions regarding doing the modification. It defiantly was not a matter of "cutting a jumper" to remove the input pad. You need remove the pad parts and change the number of turns in a transformer. Defiantly would void the warranty and make factory repairs iffy depending on Elecraft's policies. Other manufacturers I have worked with would restore the amp to factory while repairing it. As a ham you are not limited to the 15 db gain restriction - the manufacturer is but not you. 73 George AI4VZ -Original Message- From: Charlie T Sent: Thursday, June 18, 2020 9:06 AM To: 'Nr4c' Cc: Elecraft@mailman.qth.net Subject: Re: [Elecraft] Future of KPA500 & KAT500 Isn't there some sort of "jumper" or ???, that will increase the gain to something other than the ridiculous and prohibitive +13 dB figure, for "international" (wink-wink) sales, sorta like the "MARS" mod in almost all radios these days? 99.9% of the chicken band users today are happy with their 5 watt radios.

Re: [Elecraft] Future of KPA500 & KAT500
Isn't there some sort of "jumper" or ???, that will increase the gain to something other than the ridiculous and prohibitive +13 dB figure, for "international" (wink-wink) sales, sorta like the "MARS" mod in almost all radios these days? 99.9% of the chicken band users today are happy with their 5 watt radios. However, that restrictive and useless +13 gain law does NOTHING to stop the REALLY big guns on 27.025 who typically run amps using tubes that have HANDLES on them!

Re: [Elecraft] Future of KPA500 & KAT500
I like combining them. And update to a lightweight switching power supply. Should be less expensive to produce and eliminates dealing with 120 vs 230, transformer taps, voltage sag under load. I have them already and this adds no additional functionality, except easier when I shuffle things around in the shack.

Re: [Elecraft] Future of KPA500 & KAT500
Having both plus the KPA1500 (same height as the K4), that would be a challenge without a major rework. Not just in squeezing it in, but still allow for adequate cooling. If they choose to go down that path, I'd hope they keep the third antenna port (only two on the KPA1500). As for their long term plans; we know they listen but are sly in responding until it's time to announce. 73, Rick NK7I On 6/17/2020 7:19 AM, hawley, charles j jr wrote: Hey, that's a thought.

Didn't intend to mean upgrade. 73 Don NA6Z On Tue, Jun 16, 2020 at 9:47 PM Don Putnick wrote: > With the sunset of the K3S, what are the plans for the future of the > KPA500 and KAT500?

Re: [Elecraft] Future of KPA500 & KAT500
I think it depends on the use case. I’d rather see the KPA500 v2 made lighter and a third antenna port added. The real icing on the cake would be 10w in and 500w out but I won’t touch that topic too much! This would make it a better “portable” amp.

Re: [Elecraft] Future of KPA500 & KAT500
Charles, your thinking on pairing the amp with tuner inside had great merit and housing it inside of a K4 enclosure. Heck man that is the best idea I have heard. I hope Elecraft takes the move on that especially now since they already have the format for the case made and only have to change the front and back plates and G2G. 73, Morgan Bailey NJ8M On Wed, Jun 17, 2020 at 9:21 AM hawley, charles j jr wrote: > Hey, that's a thought.

Re: [Elecraft] Future of KPA500 & KAT500
I read it as what would their future availability be, nothing to do with updating. Not uncommon to read about the KPA500 being paired with other transceiver brands.
